Pros and cons of SSD and HDD
The tasks of drives of each class are reduced to one thing: to provide the user with a working operating system and allow him to store personal data. But both SSD and HDD have their own characteristics.
SSDs are much more expensive than traditional HDDs. A simple formula is used to determine the difference: the price of a drive is divided by its capacity. As a result, the cost of 1 GB of capacity in currency is obtained.
So, a standard 1 TB HDD costs an average of 50 (3300 rubles). The cost of one gigabyte is 50/1024 GB =
Hard magnetic disks have a very long (of course, by the standards of the development of computer technology) history. In 1956, the IBM company released the little-known computer IBM 350 RAMAC, which was equipped with a huge 3.75 MB storage device by those standards.
THESE cabinets could store as much as 7.5 MB of data
To build such a hard drive, 50 round metal plates had to be installed. The diameter of each was 61 centimeters. And this whole gigantic structure could store. Just one MP3 song with a low bitrate of 128 Kb / s.
Until 1969, this computer was used by the government and research institutes. Even some 50 years ago, a hard disk of this size was quite suitable for humanity. But the standards changed dramatically in the early 80s.
Floppy disks of the 5.25-inch (13.3 centimeters) format appeared on the market, and a little later, 3.5 and 2.5-inch (laptop) versions. Such floppy disks could store up to 1.44 MB of data, and a number of computers at that time were supplied without a built-in hard drive. THOSE. To start the operating system or software shell, you had to insert a floppy disk, then enter several commands and only then start to work.
Throughout the history of the development of hard drives, several protocols have been changed: IDE (ATA, PATA), SCSI, which was later transformed into the now famous SATA, but all of them performed the only function of a “connecting bridge” between the motherboard and the hard drive.
Here are 2.5 and 3.5 inch floppy disks with a capacity of fifteen hundred kilobytes, the computer industry has switched to hard drives of the same size, but thousands of times more memory. Today, top-end 3.5-inch HDDs reach 10 TB (10240 GB) 2.5-inch. up to 4 TB.
The history of SSDs is much shorter. In the release of a memory storage device that would have only moving parts, engineers started thinking back in the early 80s. The emergence in this era of the so-called bubble memory was met with very hostility and the idea proposed by the French physicist Pierre Weiss back in 1907 did not take root in the computer industry.
The essence of bubble memory was the breaking up of magnetized permalloy into macroscopic regions, which would have spontaneous magnetization. The unit of measurement for such a storage device was bubbles. But most importantly, there were no moving hardware parts in such a drive.
They forgot very quickly in bubble memory, and only remembered during the development of a new class of drives. SSD.
SSDs appeared in notebooks only in the late 2000s. In 2007, a budget OLPC XO-1 laptop entered the market, equipped with 256 MB of RAM, an AMD Geode LX-700 processor with a frequency of 433 MHz and the main highlight. 1 GB NAND flash memory.
OLPC XO-1 was the first laptop to use a solid state drive. And soon the legendary line of Asus EEE PC netbooks with the model 700 joined him, where the manufacturer installed a 2 GB SSD-drive.
In both laptops, the memory was installed directly onto the motherboard. But soon the manufacturers revised the principle of organizing the drives and approved the 2.5-inch format connected via the SATA protocol.
The capacities of modern SSDs can be up to 16 TB. Most recently, Samsung introduced just such an SSD, albeit in a server version and with a price that is cosmic for an ordinary man in the street.
,05 T.E. 5 cents (3.2 rubles). In the SSD world, everything is much more expensive. SSD with a capacity of 1 TB will cost on average 220, a), which is 4.4 times more expensive than HDD.
The good news is that the cost of SSDs is rapidly falling: manufacturers are finding cheaper solutions for the production of drives and the price gap between HDD and SSD is narrowing.
FAQ Battle of HDD and SSD. What is the difference and which one to choose?
Until recently, when buying a new computer and choosing a drive to install, the user had the only choice. a hard disk drive HDD. And then we were interested in only two parameters: spindle rotation speed (5400 or 7200 RPM), disk capacity and cache size.
In 2009, a new category of Solid State Drives (SSD) enters the market, which immediately established themselves as more reliable and faster alternatives to HDD.
Let’s take a look at the pros and cons of both types of drives and make a visual comparison between HDD and SSD.
Principle of operation
A traditional drive or as it is commonly called a ROM (read only memory) is required to store data even after a complete power outage. Unlike RAM (random access memory) or RAM, data stored in memory is NOT erased when the computer is turned off.
A classic hard drive consists of several metal “plates” with a magnetic coating, and data is read and written using a special head that moves above the surface of the disk rotating at high speed.
Solid state drives have a completely different working principle. The SSD completely lacks any movable components, and its “fillings” look like a set of flash memory chips located on one board.
Such chips can be installed both on the system motherboard (for especially compact models of laptops and ultrabooks), on a PCI Express card for stationary computers or a special slot in a laptop. The chips used in SSDs are different from those that we see in a flash drive. They are much more reliable, faster and more durable.
A favorite “delicacy” of any HDD-hard drive is large files: movies in MKV format, large archives and images of BlueRay disks. But as soon as you load the hard drive with hundreds or two of small files, photos or MP3 tracks, the reading head and metal pancakes become confused, as a result of which the write speed drops significantly.
After the HDD is full, deleting / copying files multiple times, the hard disk starts to work slower. This is due to the fact that parts of the file are scattered over the entire surface of the magnetic disk, and when you double-click on any file, the reading head is forced to search for these fragments from different sectors. This is how time is wasted. This phenomenon is called fragmentation, and as a preventive measure to speed up the HDD, a software and hardware process is provided for defragmentation or ordering such blocks / parts of files into a single chain.
It is recommended to perform defragmentation periodically on all types of HDD-drives, thereby maintaining their optimal speed.
The principle of operation of an SSD is fundamentally different from an HDD, and any data can be written to any sector of memory with further instant reading. This is why defragmentation is not necessary for SSD drives.
Average and maximum SSD and HDD capacities
Just a few years ago, there was not only a numerical but also a technological gap between the maximum capacity of an HDD and an SSD. It was impossible to find an SSD that could compete with HDD in the amount of stored information, but today the market is ready to PROVIDE the user with such a solution. True, for impressive money.
The maximum SSD capacity that is offered for the consumer market is 4TB. A similar option was presented by Samsung in early July 2016. And for 4 TB of space you will have to shell out 1499.
The base HDD memory for laptops and computers manufactured in the second half of 2016 ranges from 500 GB to 1 TB. Models similar in power and characteristics, but with an installed SSD-drive, are content with only 128 GB.
Reliability and service life
Remember the main advantage of SSDs? That’s right, no moving parts. That is why you can use a laptop with an SSD in transport, off-road conditions, or in conditions inevitably associated with external vibrations. This will not affect the stability of the system and the drive itself. Data stored on the SSD will NOT be damaged even if the laptop is dropped.
In HDD, everything is exactly the opposite. The read head is located just a few micrometers from the magnetized discs, and therefore any vibration can lead to the appearance of “bad sectors”. areas that become unusable. Regular jolts and careless handling of a computer, which works on the basis of an HDD, will lead to the fact that sooner or later such a hard drive will simply “crumble” or stop working, speaking in computer jargon.
Despite all the advantages of SSDs, they also have a very significant drawback. a limited cycle of use. It directly depends on the number of memory blocks rewriting cycles. In other words, if you copy / delete / re-copy gigabytes of information every day, you will very soon cause the clinical death of your SSD.
Modern SSDs are equipped with a special controller that takes care of evenly distributing data across all SSD blocks. Thus, it was possible to significantly increase the maximum operating time of 3000. 5000 cycles.
How durable is an SSD? Just take a look at this picture:
And then compare with the warranty period, which the manufacturer of your particular SSD promises. 8. 13 years for storage, believe me, not so bad. And do not forget about the progress that leads to a constant increase in the capacity of SSDs at an invariably decreasing cost. I think in a few years your 128 GB SSD can be classified as a museum piece.
SSD and HDD speed
Yes, it is for this indicator that users overpay when they prefer SSD storage. Its speed is many times higher than the indicators that HDD can boast of. The system is able to boot in just a few seconds, it takes much less time to launch heavy applications and games, and copying large amounts of data from a many-hour process turns into a 5-10 minute.
The only “but”. data from the SSD drive is deleted as quickly as it is copied. Therefore, when working with an SSD, you may simply not have time to press the cancel button if one day you suddenly delete important files.
The battle of storage sizes has always been caused by the type of devices in which they are installed. So, for a stationary computer, it is absolutely uncritical to install both a 3.5-inch and a 2.5-inch disk, but for portable devices such as laptops, players and tablets, a more compact version is needed.
The smallest serial version of the HDD was considered the 1.8-inch format. This is the disc used in the discontinued iPod Classic.
And no matter how hard the engineers tried, they failed to build a miniature HDD-hard drive with a capacity of more than 320 GB. It’s impossible to break the laws of physics.
Things are much more promising in the SSD world. The generally accepted format of 2.5 inches has become such NOT because of any physical limitations with which technologies face, but only because of compatibility. In the new generation of ultrabooks, the 2.5 ” format is gradually being phased out, making the drives more compact and the cases of the devices thinner.
Rotation of disks even in the most advanced HDD-hard drive is inseparably associated with the occurrence of noise. Reading and writing data sets the disk head in motion, which rushes at an insane speed across the entire surface of the device, which also causes a characteristic crackle.
SSD-drives are absolutely silent, and all processes taking place inside the chips pass without any accompanying sound.
Summing up the comparison of HDD and SSD, I would like to clearly define the main advantages of each type of storage.
Advantages of HDD: capacious, inexpensive, affordable.
Disadvantages of HDD: slow, afraid of mechanical stress, noisy.
SSD advantages: absolutely silent, wear-resistant, very fast, fragmentation-free.
Disadvantages of SSD: expensive, theoretically have a limited service life.
It is no exaggeration to say that one of the most effective methods for upgrading an old laptop or computer is to install an SSD instead of an HDD. Even with the most recent version of SATA, you can achieve three times the performance gain.
Answering the question, who needs this or that drive, I will give several arguments in favor of each type:
They need HDD:
- Store huge collections of movies, music and programs
- Dream of buying a good laptop up to 400-500
- Ordinary users who use a computer for surfing, multimedia entertainment and social networks
- Those who work with video and photos (for storage)
They need an SSD:
- Travel lovers and those who do not sit still
- Someone who likes to watch the instant launch of applications and the system itself
- Those who work with video and photos (for the processing itself)
- Musicians and sound engineers (remembering the point in the noise)
And if you feel that your computer is clearly not coping with ordinary tasks, and the noise of the constantly clicking and buzzing hard drive is a headache, it’s time to install an SSD. And the ideal tablet for all occasions: SSD. for applications, system and work, HDD. for data storage.
There is NOT a lot of disk space. External USB drives can be an excellent solution, because their maximum capacity in the middle price segment can reach 4 TB, and this is quite enough to store a golden collection of movies in Full HD quality.
As an option:
You can find more options at a reasonable price here.
SSD. next generation storage
SSD memory appeared later than hard drives and is very different from its predecessor. Solid state devices are non-mechanical. The “insides” of such drives look like a set of microcircuits. The field of application of SSD is quite wide. They are installed both on a motherboard, which is important for thin laptops, and on a PCI Express card or in a special slot for desktop PCs.
Note: Like HDDs, SSDs come in external and internal versions. Internal. for installation directly into the system, and portable. for quick and easy connection to the device via USB.
All solid-state devices work on NAND memory. However, when choosing, you should pay attention to its type. There are three main types.
Drives last at least three years if used correctly.
Expensive, but memory longevity is about 10x that of MLC.
The golden mean in terms of value and durability.
The main difference between all types is the number of bits that are stored in a memory cell. They affect media life and cost.
Note: The durability is also affected by the controller. This component is responsible for the equal distribution of information across the cells and the load on the device, respectively.
When choosing an SSD, IOPS is also taken into account. the number of input and output procedures per second. It reflects the ability of the device to work with a large volume of files.
Interesting: despite the fact that SSDs are sometimes called large flash drives, the chips used in such drives are different from those used in flash drives. They are safer and faster.
HDD. classic hard drive
Such a carrier consists of several magnetically sputtered plates made of metal. A special head that moves above the surface of the disk (and it rotates at high speed) reads and writes information.
The differences between the models are not only in volume, but also in the speed with which the devices work. This parameter depends on how fast the disc is spinning. The indicator is indicated in revolutions per minute, for example, 5200 rpm, as in a half-terabyte WD 2.5 “SATA 3.0, or 7200 rpm, as in the six-terabyte DELL 3.5” SATA.
The form factor of HDD devices is also different. The two most common options are 2.5 and 3.5 inches. The first format is universal: it is installed in both laptops and desktops. The second is only suitable for desktop assemblies.
Remark: HDDs can be designed not only for indoor installation, but also be portable.
Advantages and disadvantages of HDD
Hard drive appeared much earlier than solid drive, but is still NOT losing ground. They have many advantages. Here are just the main ones:
Price-to-capacity ratio: HDDs are significantly cheaper than SSDs of the same size.
Recovering Lost Data to Hard Drive Easier Than SSD.
Due to technical features, HDDs last almost twice as long under more serious loads.
The lifespan does NOT depend on how many times the disk has read and overwritten files.
With a sudden power outage, the chance of data loss is very low compared to solid state drives.
Tip: if you want a very roomy HDD, then WD121KRYZ is perfect, because it contains 12 terabytes.
Unfortunately, there are also disadvantages:
Power consumption is higher compared to solid state drives in HDD. This means that when working with a laptop from a battery, the autonomy of the latter will be lower. HDDs also get hotter.
Mechanical parts cause abnormal noise.
Hard drives are slower than SSDs. This is noticeable both when reading and writing information, and when running resource-demanding software and the operating system itself.
HDD sensitivity to external influences is extremely high. Vibration, dropping or shock can cause malfunction. Do not forget about the susceptibility of hard drives to magnetic fields, which can also harm the drive.
Dimensions and weight: In terms of weight and compactness, the hard drive loses to the SSD. This matters when installed in a laptop, as well as for portable media.
Interesting: external HDDs are often clothed in rubberized cases, which protect the disk from vibration and mechanical damage. The terabyte StoreJet and the AC630 are just such.
SSD or HDD. which is better: the differences between 2 types of drives
Two types of information carriers are installed in a PC: a hard disk and / or a solid-state disk. Both devices are great storage options, and then choosing between them is not easy. Comparison of their features, positive aspects, and also disadvantages will help to understand which drive is better.
SSD advantages and disadvantages
As with hard drives, there are pros and cons to solid state storage too. The positive features include:
Lack of mechanics. adds SSD endurance. It is not recommended to deliberately perform a crash test, but in most cases, falling from the table and other similar “cataclysms”” will not affect SSD performance. Whereas with the slightest shake, the HDD most often starts to work unstable.
The lack of mechanical parts has a positive effect on loudness. When the solid-state drive is running, there is noise, which cannot be said about the HDD.
They give off little heat. SSDs do NOT get as hot as hard drives, even under heavy load. When installed in a PC, there is a need for extended cooling.
High speed. compared to HDD, SSD is 2-3 times faster. The responsiveness of the programs is also improved. Even “weighty” software, demanding on the system resources, begins to respond to commands almost instantly. Files are written and read faster, which is also a plus.
If an SSD is in a magnetized area, nothing will happen to it, unlike an HDD.
Interesting: if you want a living SSD, then the 970 EVO is perfect, because its maximum write resource is 1,200 TBW.
Of course, solid-state media are NOT without drawbacks:
Shorter life than hard drives: SSDs have a limited rewrite life. However, if you use them to install the OS and the main software, then the owner is unlikely to notice the difference.
Potential loss of most, and sometimes all, data due to unplanned power outages.
In terms of cost / volume ratio, HDD wins, but this cannot be attributed to a significant disadvantage, especially considering all the advantages. In addition, if we consider the SSD as a disk for the system, and the hard disk as the main one, then chasing terabytes is not at all necessary.
Both SSDs and HDDs are reliable storage media, but each has its own positive and negative qualities. So, solid-state drives are much better than classic hard drives in terms of speed, but in conventional HDDs there are restrictions on reading / overwriting. It is difficult to choose one type of storage instead of the second. Then one of the best solutions is to use both options. Hard. for those data that will often be viewed, erased and replaced. And to add speed to the PC, an SSD is useful: it can be assigned to the OS and resource-intensive utilities.
Which SSD is better to choose and why
Everything You Need to Know Before Buying a Desktop or Laptop Solid State Drive.
If you are building a powerful computer or want to speed up an old one, then an SSD will come in handy. Finally, the cost of THESE drives has dropped so much that they can be considered a reasonable alternative Hard Disk Drive (HDD).
The SSD features listed below will help you choose the best drive that is compatible with your computer and meets your needs.
SSD 2.5 “
This form factor is the most common. The SSD looks like a small box that resembles an ordinary hard drive. SSD 2.5 “the cheapest, but at the same time their speed is enough for most users.
SSD 2.5 Samsung 850 EVO
Which SSD is faster
In addition to the type of memory, other characteristics, such as the model of the controller installed in the drive and its firmware, affect the performance of an SSD. But these details are often not even mentioned in the description. Instead, endpoints of read and write speed appear, which are easier for the buyer to navigate. So, when choosing between two SSDs, all other things being equal, take the drive whose declared speeds are higher.
Remember that the manufacturer indicates only theoretically Possible speeds. In practice, they are always lower than stated.
Which form factor to choose: SSD 2.5 “, SSD M.2 or other. 2. Which memory is better: MLC or TLC
According to the number of bits of information that can be stored in one flash memory cell, the latter is divided into three types: SLC (one bit), MLC (two bits) and TLC (three bits). The first type is relevant for servers, the second two are widely used in consumer drives, so you have to choose from them.
MLC memory is faster and more durable, but more expensive. TLC is correspondingly slower and withstands fewer rewrite cycles, although the average user is unlikely to notice the difference.
The description of the drive can also indicate the type of mutual arrangement of memory cells: NAND or 3D V-NAND (or just V-NAND). The first type implies that the cells are located in one layer, the second. in several layers, which allows you to create an SSD of increased capacity. 3D V-NAND Flash is more reliable and performant than NAND according to developers.
compact form factor, which makes it suitable even for extremely thin laptops with space for a 2.5 SSD “. It looks like an oblong joint, it is installed not in a separate compartment of the case, but directly on the motherboard.
SSD M.2 ADATA SU800
To connect to the board, each M.2 drive uses one of two interfaces: SATA3 or PCIe.
Pcie is several times faster than SATA3. If you choose the first one, then it is worth considering a few more things: the version of the interface and the number of lines connected to the connector for data transmission.
- The newer the PCIe version, the higher the bandwidth (data exchange rate) of the interface. Distributed in two versions: PCIe 2.0 (up to 1.6 GB / s) and PCIe 3.0 (up to 3.2 GB / s).
- The more data lines are connected to the SSD connector, the higher its bandwidth is. The maximum number of lines in an M.2 SSD is four, in this case, in the description of the drive, its interface is referred to as PCIe x4. If there are only two lines, then. PCIe x2.
Less popular form factors
Your computer may NOT have a 2.5 SSD bay “, and the motherboard will not have an M.2 connector. The owner of a thin laptop may face such an atypical situation. Then for your system you need to choose SSD 1.8 “or mSATA. check the documents for the computer. These are rare form factors that are more compact than SSD 2.5 “, but inferior in data transfer speed to M.2 drives.
Kingston SSDNow V180 Compact Drive 1.8 Form Factor “
Additionally, Apple’s thin laptops may NOT support Traditional Form Factors either. In them, the manufacturer installs a proprietary SSD format, the characteristics of which are comparable to M.2. So, if you have a thin laptop with an apple on the lid, check the supported SSD type in the documentation for your computer.

M.2 SSD Compatibility with Computers
Before buying an M.2 SSD, you should make sure it will fit your motherboard. To do this, first check the physical and then software compatibility of the connector on the drive with the slot on the board. Then you need to find out the length of the drive and compare it with the allowable length of the socket allocated for M.2 in your system.
Physical compatibility of interfaces
Each connector on the motherboard for connecting M.2 drives has a special cutout (key) of one of two types: B or M. At the same time, the connector on each M.2 drive has two BM cutouts at once, rarely only one of two keys: B or M.
You can connect an SSD with a B-connector to the B-connector on the board. To the M-slot, respectively, a drive with a M. SSD type connector, the connectors of which have two M B cutouts, are compatible with any M.2 slots, regardless of the keys in the latter.
M.2 SSD with key B M (upper) and SSD M.2 with key M (lower) / www.Wdc.com
So, first make sure your motherboard has an M.2 SSD slot at all. Then find out the key of your connector and select a drive, the connector of which is compatible with this key. Key types are usually indicated on connectors and slots. In addition, you can find all the necessary information in the documents for the motherboard and drive.
Logical compatibility of interfaces
For an SSD to fit your motherboard, it is not enough to take into account the physical compatibility of its connector with the connector. The fact is that the drive connector may NOT support the logical interface (protocol) that is used in the slot of your board.
Therefore, when you understand the keys, find out what protocol is implemented in the M.2 slot on your board. It can be SATA3 and / or PCIe x2 and / or PCIe x4. Then choose an M.2 SSD with the same interface. Please refer to the device documentation for supported protocols.
Another nuance on which the compatibility of the drive with the motherboard depends is its length.
In the specifications of most motherboards, you can find the numbers 2260, 2280 and 22110. The first two digits in each of them indicate the supported width of the drive. It is the same for all M.2 SSDs and equals 22 mm. The next two digits are the length. Thus, most boards are compatible with 60, 80 and 110 mm drives.
Three M.2 SSD drives of different lengths / www.Forbes.com
Before purchasing M.2, be sure to check the supported length of the drive, which is indicated in the documents for the motherboard. Then choose an SSD that matches this length.
SSD 2.5 compatibility “with computers
An SSD of this form factor can be installed in any desktop or laptop that has a free 2.5-inch drive bay. If your system only has room for an old 3.5 ” HDD, you can fit a 2.5 ” SSD into it too “. But in this case, look for an SSD model that comes with a special latch.
Like modern HDDs, SSD 2.5 “connects to the motherboard using SATA3. This connection provides bandwidth up to 600 MB / s. If you have an older motherboard with a SATA2 connector, you can still connect a 2.5 SSD “, but the bandwidth of the drive will be limited by the old version of the interface.
Disadvantages of SSD over HDD
Expensive: SSD have been falling for years, but their predecessors, HDDs, remain substantially cheaper and more affordable. One of the reasons for the biting may be that the popularity of the former is currently much lower than that of classic SSDs. Perhaps in a few years everything will change in favor of SSD.
Loss of data due to power outages: While SSDs are more reliable storage of information, a sudden power outage can affect the stored data. If the power is suddenly interrupted, you risk losing all data.
Limited lifespan: The biggest disadvantage of an SSD is that it loses its write potential over time. This is because it is not possible to change the number of bits on the disk. In order to fix this, it is necessary to delete and rewrite a large block of data, since when information is erased in the SSD cell, a residual charge remains in it. This charge increases the resistance of the cell and eventually the electric current can stop passing through it and becomes useless.
In the previous article, we have already discussed the method of creating conditions for stable wear of disk resources, however, no matter how we would like it, this only leads to slower degradation of the SSD, but NOT to it. “immortality”. It is important to note that the indicated negative moment in the operation of the disk does not in any way affect its ability to read information, since during this process the charge value does not change.
Fortunately, manufacturers have ways to address THESE issues. In particular, a hybrid disk (SSHD), based on a method such as SSD Cahing, which should not be confused with the cache memory inside the SSD. When using this method, frequently used data and applications are copied to the SSD, which acts as a cache, and the HDD acts as the main storage device. Thus, you have a lightning-fast disk with important and frequently used data, and HDD for storing music and movies, which can be loaded and deleted without consequences.
Summing up the results of the first half of the article, SSDs have an incomparable advantage over HDD in terms of data recording speed, but the previous generation of disks is still a financially more profitable option. The rise in popularity of SSDs does not yet mean that HDDs will soon leave the market. To this day, new technologies are being created, such as HAMR (Thermal Assisted Magnetic Recording). the development of more advanced hard drives that will help them remain a profitable choice these days. Hard drives have done an incredible job and are an important branch in the evolution of information storage. Given the pace of development of computer technology, it is likely that soon a formidable candidate for HDD. SSD will take the place of its ancestor. Not so long ago, Samsung launched a module “PM1633a 15TB SSD 15TB”, Which can be considered one of the first steps towards a bright future for solid state drives.
We’ve discussed the difference between the two competing drive types, but we still have NOT touched on the important topic of why you should buy an SSD. Time does not stand still, everything is developing and new solid-state drives are threatening to soon seize the computer equipment market in the field of information storage.
Let’s go straight to the reasons why SSDs look so much better than their predecessors.
Reasons to discover an SSD
Summing up, we can safely say that although SSDs are NOT devoid of their shortcomings, their advantage is undeniable. It is quite possible that in the very near future they will become a new standard for data storage, but for now the hybrid option will be the best option. in which you connect both SSD and HDD to the PC, which perfectly complement each other.
Difference between SSD and HDD, which is better and more reliable for your PC
It’s no secret that there is an obvious difference between SSD and HDD. You can read more about SSD and what it is in our article. “What is SSD and how does it work. ” In this part, we will discuss the main differences between the two current types of drives and 7 reasons why it would be beneficial for you to switch to an SSD.
First, let’s look at the difference between the two types of information stores.
Advantages of SSD over HDD
Fast Boot: Solid State Drives can offer very fast processing speeds. In particular, thanks to the SSD, the operating system will be able to start with, as it previously seemed, incredible lightning speed. Any SSD can run your OS twice as fast as a hard drive.
Fast Reading and Writing: The SSD is capable of handling around 500 megabytes per second when comparing the average solid state drive to 150 megabytes per hard drive. SSDs can be useful for you if you are, say, a graphic designer using software that requires a huge amount of PC resources, or a hardcore gamer who requires high performance for games.
Low power consumption: these storage devices are designed in such a way that they consume significantly less power for their operation than possible analogues among HDD. This way your laptop battery will last longer and you can save a lot of money on your electricity bill in the long run.
Low noise level: Spinning hard drives are known to generate enough noise to annoy the user if they need to focus on something important. SSDs can make life a lot easier if you want your device to make as little noise as possible during operation.
Shape and size: SSD, due to its compact size, can be installed either in the place of an old HDD, or make it an external drive.
What is SSD and how does it work
It would seem that here it is. the technology of the future! But no! A solid drive has a number of disadvantages over a hard drive.
They prevent this type of disc from reaching a wide market segment and getting ahead:
- Sky-high price. The price of one SDD board for the same volume is 20 times higher
- Risk of data loss. It is impossible to recover an accidentally deleted file on a system with such a hard disk. It just isn’t saved there. You can “remove” files from the HDD, even if the computer completely flew from power outages and all the nodes burned out. Of course, this will require certain physical and material costs, but still!
- Volume. HDD for 1 TV is not news for a good laptop of the middle and high price range. But the SSD pumped up. 128 GB in a laptop and the price is already starting to “bite”!
- Life time. Cells tend to wear out over time. The more write cycles the drive has experienced, the closer its last hour. With an average user load, it will come after 3-5 years of device operation.
Note! There are a number of Special utilities that can be used to check the level of wear on the board. At startup, it shows how many cycles of recording user information have already completed and determines the Predicted remaining life of the solid-state board.

All modern portable computer devices are assembled by the manufacturer with two types of disks: hard drives and solid-state drives. What is the difference between them and how can an ordinary consumer make the best choice??
Everything about HDD
Externally, the hard drive looks like a box with round magnetized plates and a spindle for reproducing data at a speed of several thousand revolutions per minute. It is on them that all information about the software of the device is stored.
The speed of the computer largely depends on the speed of reading the software, i.e. the frequency of rotation of the head. The most common of them are 5400 and 7200 rpm. Speed indicators for 10,000 and more thousand rpm are indicators of a central server and equipment for administration, this does not occur in everyday life. The read and write parameters are not so critical for home PCs. It’s better not to Zaostrov on this. Laptops come with a 2.5-inch hard drive.
Everything about SSD
The solid-state drive differs from traditional hard drives in its ultra-high read and write performance. How is this achieved? For example, when searching for the application you need at this moment, the HDD disk will be sequentially read by software software with a metal spindle, until it reaches the desired place. SSD is a set of microcircuits on a single board, where all infa is decomposed into sectors and is visible at a glance. Take and read any file you need, from anywhere, at the most convenient moment. In fact, the latest generation hard drive is 30-40-50 times faster than its previous brother! What does this give the common user? Very responsive response and an increase in the number of operations per second. In simple terms, it is a tremendous pleasure from working on the device, which does not slow down. details here.
Who needs a laptop with an SSD drive?
What conclusion follows from all of the above? A solid state drive is an expensive component in a laptop computer system. For the common man in the street, surfing the Internet, communicating in social networks and on Skype does not make sense to spend a lot of money on this modern technology. What should the user choose for household use? The answer is simple: a mid-range laptop with an HDD. Large amounts of information can be safely stored here.
Remember! If working at high speed is a priority for a laptop user, it is better to purchase a device on an SSD drive. A large number of essential files can be transported to cloud storage or to a miniplash.
The technical characteristics of solid drives mean that information from the device will be read very quickly. Who needs it the most? 3D max specialists, computer designers. Maybe when processing large volumes of photo and video files. Electronic organization of data transmission makes working with visual information more comfortable and faster.
Advanced users of modern programs solve the problem in a tricky way. An external hard drive is bought for a laptop on a hard drive. A more reliable HDD is used to store data, and the board is responsible for ultra-fast complex tasks.
The most ardent fans and buyers of SSD-type laptops are advanced gamers. This has its drawbacks: modern game programs are so large files that it is still better to choose hard drives for storage. It is worth paying attention to devices with a hybrid storage type, the so-called SSHD.
SSDs are completely silent. But the HDD is available. Although increased noise from the hard drive may indicate a malfunction, it can help to respond in time and save information.
SSDs weigh almost nothing, but HDDs are quite bulky. There is nothing more to add here.
HDD and SSD on modern computers and laptops
Now in laptops and personal computers, there are both types of drives. Often new laptops are equipped with only one HDD, but have 1-2 M.2 slots for installing SSDs if necessary. That is, if the future owner decides to arrange an upgrade and install additional memory, he can easily do it himself. Even if the laptop has one more slot for installing an SSD, it will be able to dismantle the optical drive and install the SATA drive in its place.
SSD types. And they may also differ in size. Therefore, it is important to understand what type of memory your motherboard supports.
With regard to personal computers, combined types of memory. i.e. HDDSSD. Of course, it all depends on the specification of the motherboard.
Typically, SSDs are used to install the operating system, and HDDs are used to store data.
Differences between SSD and HDD
HDD is the most popular type of storage today. A hard disk (also called a hard drive) records all digital information on special aluminum disks, and reads it out using a magnetic head (an involuntary comparison with a Gramophone immediately comes).
SSD is a completely new type of storage without movable components, which uses several microcircuits instead of disks, a kind of flash cards on RAM. Solid-state drives offer increased data throughput and impressive power efficiency. They work several times faster than the good old HDD.
Installing an SSD under an operating system is a good upgrade for a computer. Such an upgrade will help to increase the speed of reading and writing data, improve the performance of programs and games, and speed up system loading. It is often written on the network that installing an SSD is also a good way to revive an old computer or laptop, but this is only relevant if the motherboard is equipped with a SATA 3 slot, otherwise you DO NOT feel a noticeable increase in performance, neither you nor the system. the old slots DO NOT support high speed data reading.
Now let’s move on to a detailed analysis.
Device cost and volume
The most popular SSDs are 128GB. 512GB. The demanded volume of HDD for home is 1-2 TB. It should be noted that both types of drives have long supported large volumes (from 6 TB and above), but the choice in favor of HDD falls due to the difference in cost, as you already understood.
Which is better. SSD or HDD?
We figure out which drive is better suited for storing data on home computers and laptops. SSD or HDD.
I want to start right away with the fact that SSD and HDD occupy completely different niches. HDD is more cost-effective and reliable in the field of storing large amounts of data, therefore our review will only concern comparing drives for home, in situations where they are not used at full capacity 24 / 7.
A solid-state drive is good for everyone. it does not heat up, does NOT spend a lot of energy, saves laptop battery resources, which cannot be said about a gluttonous hard drive.
Resistance to physical influences
The hard drive is more vulnerable to physical impacts. vibration, shaking, falling. SSDs are more resistant to this kind of stress, but are less resistant to power surges.
With such damage, nothing will help
HDDs last longer on average than SSDs. But here you need to understand an important point. the lifespan of an SSD directly depends on its volume: there is a certain number of rewriting cycles in a solid-state drive, and the larger the volume, the greater the resource. That is, a 512GB SSD will last twice as long as a 256GB drive. Of course, under the same conditions.
Easy to install
It all depends on the model of the motherboard or laptop. if your computer supports a modern slot for installing M.2 (SATA, NVMe or mSATA), then you just need to insert a memory strip into the desired socket.
Installing an M.2 SSD
If you are a user of more than one modern laptop, and it is equipped with only one slot for a hard drive and an optical drive, then you will need to dismantle the drive, transfer the HDD to it using a special adapter and install a SATA SSD in the slot for the hard drive.
