Internal solid storage. What to choose: Hard disk or solid-state drive? Comparison with HDD.

Hi friends! As they spoke in Russia: "Any merchant your product praises" and no matter how much you read different articles about solid-state sSD drives, the same opinion is unlikely to meet. Someone came something and decided to buy solid State Drive Samsung, who Toshiba, and others decided by anywhere to purchase SSD OCZ VERTEX orKingston.

About one and a half ago, we decided to buy firmly with your friends on SSD solid-state drive, everyone has them, and we have no. Comrades asked me to make tests of various SSD and choose the best.

Solid state drives buy not particularly well, so the sellers of computer goods do not carry them, so that they did not lie in the warehouse. So we also do it, so at my disposal was the leaders of SSD sales at that time. The most affordable of the whole company was SSD Silicon Power V70, the test of which I left for later.

In my tests, I did not really sophisticated, I installed each SSD Operational The system, then compared SSD and the usual HDD in CrystalDiskmark and AS SSD Benchmark test programs. Especially prove that SSD better An ordinary HDD I did not have to anyone. Windows installed on SSD solid-state drive loaded in 4 seconds, CrystalDiskMark test programs and AS SSD Benchmark showed full SSD superiority over the usual HDD 3-4 and even 5 times.

All the tests I made in the trading room and the information was available to customers, in short, all test SSDs disassembled, besides, that day was good for sales and even a single SSD left on the showcase, well, I think I remained without a solid-state drive! And then I remembered the SSD Silicon Power - V70. In principle, I knew this good manufacturer from Taiwan, but still wanted something else, for example Crucial or Plextor!

I decided to test it, too, to test at the end of the working day and after tests, I was a little surprised, the V70 turned out to be a significant solid storage device with no inferior to other SSD tested and sold by me. And the program Sisoftware Sandra generally awarded him first place.

During the year, where he just did not work: both on a laptop and in different stationary system blocks and instead of a flash drive, I dragged him in my pocket and on the floor dropped, but nothing, still works fine.

Well, okay, the chatter is enough, I turn to the most basic in the article, answers to your questions on the solid-state drive and at the end of the article will give some tests proving - SSD to install operating system This is what the doctor prescribed.

All your questions relating to SSD solid-state drives.

1. What is internal organization SSD? Based on what flash memory Nand: SLC, MLC or TLC buy SSD?

2. What manufacturer SSD prefer?

3. Is the service life of the SSD solid-state drive really limited? After how many years of use, my SSD fails?

4. Does the user threaten the loss of all recorded data in case of exceeding the memory microcircuit resource?

5. Is it worth it to extend the life of SSD, disable hibernation, paging file, recovery, disk indexing service, disk defragment, Prefetch technology, to carry cache browser and temporary file directory to another hard drive and so on?

6. How faster the SSD of an ordinary hard disk?

Compare different SSD by productivity

It is important to know not only the average speed of consistent reading and writing on the SSD, but also the SSD-silent producers - speed random recording Blocks of 512 KB and 4 KB! Disk activity in most users occurs mainly in such areas!

When comparing SSDs of various manufacturers in the AS SSD Benchmark program, we can see such a result, for example:

My SSD Silicon Power V70 showed:

Speed \u200b\u200bof consistent reading and recording 431 MB / s (reading), 124 MB / s (recording)

Speed \u200b\u200bin reading and writing blocks 4 kb, turned out 16 MB / s (reading), 61 MB / s (recording)

SSD of another manufacturer. As you can see, high (higher than my SSD) Speed \u200b\u200bof consistent reading and recording 484 MB / s (reading), 299 MB / s (recording), but there is a sediment in read / write blocks 4 KB, namely 17 MB / s (reading), 53 MB / s (recording).This means that this SSD is no faster than mineAlthough on the box of this SSD, 500 MB / s figures can be collapsed.

With an innode on the computer component market hard drives Presented by two main types - SDD and HDD. Which one is better? Let's figure it out in detail in this matter.

HDD - Classic Hard Drive

HDD. - This is a classic hard disk, which is a box where round magnetic plates and reading heads are placed. On magnetic plates, data is stored, and the reading heads, respectively, are read. The principle of operation of HDD is similar to a gramophone, except the speed of rotation of the spindle is much faster. The HDD spindle spins the magnetized plates at a speed of 5400 and 7200 revolutions per minute. These are the most common spindle speeds at HDDs intended for user computers. Spindle speed can also be much more - for example, 10,000 and more revolutions per minute, but these are already standards of server equipment.

What gives the speed of rotation of the spindle HDD? This indicator often measures the speed of reading and writing a hard disk of data - the greater the speed of rotation of the spindle, the greater the speed of reading and writing data. But this is not quite the case, since the other indicators affect the speed of HDD - this is the density of recording and time of arbitrary access.

The higher the record density indicator, the more high-speed will be HDD. Record density in modern HDD - 100-150 GB / sq. M. With an indicator of arbitrary access, the other vice versa, because this is the time for which the hard disk will perform the operation of reading or writing data on any of the magnetic plates. Consequently, the less this time, the better. The range of this parameter, as a rule, ranges from 2.5 to 16 mc.

Thus, in the computer's work, the difference between two HDDs with a spindle speed in 5400 and 7200 may be invisible.

HDD also differ physical dimensions and B. specifications Models are indicated according to their width. This is a size of 3.5 inches - standard size HDD for PC assembly - and 2.5 inches - size HDD for laptops.

SSD - Hard disk of the new format

SSD. - In the technical specifications of computer devices, you can also meet its other name "Solid State Drive" - \u200b\u200bin fact, this is a volumetric flash drive with a huge, compared to HDD, read speed and write data. SSD faster than HDD 3-4 times. On full windows downloadMounted on SSD will need no more than 10 seconds, while this operating system on HDD will load two minutes.

What is the secret of SSD speed? HDD, for example, when launch Windows He spends time on the search for sectors on the magnetic plate and moving the reading heads. When starting exactly the same windows version With exactly the same functionality on the autoloading SSD simply reads data from a specific matrix unit, where these data are. The SSD drive runs faster and operating system, and programs, and individual files.

SSD does not add much weight with laptops, because they weigh no more than 100 g. While the 2.5-inch HDD with a weight of 700-800 g, it is clearly not easy to facilitate the daily transfer of the device.

Unlike HDD, SSD is not afraid of blows and falls. But, by dropping an intensely laptop, you can add trouble - and on the replacement of HDD, and on data recovery.

SSDs work silently, while a good high-speed HDD can even interfere with sleep if the computer is left on the night.

By the way, about recovering data, in this matter SSD loses HDD. Restore data from SSD is problematic. If, for example, a voltage jump in the power grid will occur, the SSD grows completely, and all data will be destroyed. But the HDD in exactly the same case will burn only a small fee, while all the data will remain on magnetic plates. If you wish, IT specialists will be able to restore this data. The same applies to the restoration of previously deleted data by user using a special software. On most SSD drives to restore remote files After cleaning the basket fails. But the SSD manufacturers are already working on this issue, moreover, some models of solid-state drives can physically clean the blocks of the matrix from recorded data at the time of the user's command arrival, and do it later when it becomes necessary.

But this is not the most vulnerable area of \u200b\u200bsolid storage. Their disadvantages are also essential, as well as advantages over HDD.

First, this is the price. SSD is very expensive. At the price of the SSD drive with a capacity of 60 GB, you can buy a good HDD on 1 TB of disk space.

Secondly, it is a small volume - SSD with a volume of 512 MB in the computer component market can be found quite rare, much more common standards are volumes of 128 GB or 60 GB. As we can see, such executions do not make SSD a full-fledged device for the needs of the user, and if we are not talking about an ultra-thin ultrabook, for the file repository, the laptop or PC will have to doweple the HDD. Using data to store only SSD, repeat, may pour out a decent amount of money.

Thirdly, SSD has a clearly established resource of use. Overwrite data on a solid-state drive can be up to 10,000 times. HDD has no such restrictions, and rarely when users change the Winchester for this reason. As a rule, it is either mechanical damage or overheating, or upgrades. Given the high cost of SSD, computer device must be equipped with a rapid memory of at least 8 GB so that you can disable the file windows swabs. After all, constant overwriting data in this file will help the SSD resource exhausted faster.

SSD or HDD: What is better to choose?

What is better than HDD or SSD? In the presence of free money, of course, SSD as part of the PC assembly or in a laptop does not hurt. Despite all the technical disadvantages of the solid-state drive, it is beneficial for use as a system partition for Windows. If the income is still not particularly positioned to serious money, a good high-speed HDD is a much more practical option.

Until recently, media operating on the principle of magnetic recording was used to store data. In the 70-80s of the past century they were flexible floppy disks, which then gave way to more reliable and roomy hard drives. Such a state of affairs was observed until the end of the last decade, until SSD appeared on the market - solid-state electronic media, devoid of movable mechanical parts and characterized by high speed.

At first they differed a small capacity and high price. The service life of these devices also left much to be desired. Therefore, the question is why I need a SSD drive, there was no unambiguous answer. With a volume of 32 or 64 GB and a price of several hundred dollars, these media seemed most expensive toy. A slight advantage in recording / reading speeds (up to 1.5-2 times) made SSD interesting only for "Gicks", seeking to squeeze the maximum performance from their PC.

But progress does not stand still, and soon more remedy and affordable solid-state drives arrived, which attracted the attention of a wide audience. The question of why need hDD SSD, became relevant than ever.

Design features, the advantages of SSD discs

To understand why put a SSD drive, you need to deal with the main advantages of such discs. It will not hurt to know the main disadvantages of these gadgets.

HDD and SSD Disk Design

The most important difference of SSD from traditional hard disks It is another principle of device and work. Unlike the NJMD, there are no mechanical components in the design of solid-state carriers. For data recording, high-speed flash memory arrays are used, access to which provides an internal controller. Such a design gives SSD next to the advantages of unavailable classic HDD.

Silent. Due to the absence of moving elements, in the process sSD works Does not make sounds.
Sustainability for shakes. Unlike HDD, where in the process of moving the device or drop the magnetic head can scratch the disk surface (thereby damaging it and stored data), SSD less Vulnerable. Of course, due to the housing, the contact can occur between the components, but the drive hidden inside the computer or laptop is sufficiently protected from it.
Small power consumption. The main consumer of energy in the railway is a motor that drives the drives. It rotates at a speed of 5, 7 or 10 thousand revolutions per minute and consumes to 95% of all electricity filed to the drive. Thus, SSD is up to 10 times more economical, which is particularly relevant for thin laptops.
High speed read / write. The magnetic data recording method has reached perfection limit. More than 100-200 MB / s in serial recording mode, without lower service life, extension of dimensions, increasing energy consumption and price increases, get from hard disk It is impossible. SSD flash memory does not have this minus and works up to 10 times faster.
Stable speed. If the information on the traditional railway railway is written to physically different discs (their HDD 2 and more constructions) or their sections - a delay caused by the need to move the read head. The speed of work is significantly reduced. A similar delay in reading the cells of the SSD flash memory array is millions of seconds of a second and does not affect significantly on overall performance.

Disadvantages of SSD.

With all the advantages, it is too early to talk about the perfection of SSD technology. The disadvantages of such drives are not enough low cost (3-10 times more expensive than HDD in terms of 1 GB of memory) and a limited resource of the work (from 10 thousand to 1 million cycles of rewriting to the cell). This indicator of HDD is theoretically unlimited, and in practice there are tens of millions of cycles.

Another minus of solid-state drives is an electrical vulnerability: when the high voltage caused by the problems of the power supply, the controller is burning, and the flash drive is combustible.

SSD drives - why are they needed

Knowing the main advantages of solid-state drives, answer the question "Why do I need an SSD disk to a computer?" much easier. The purchase of this gadget will allow, first of all, to increase the comfort of the use of the gadget and extend its time autonomous work (if it is a portable PC). High speed performance will be positively affected by OS load time, opening documents and performance in games.

Why SSD disc is needed in a laptop

If the case touches the laptop, then the question "why needs SSD" at all you can not put on a discussion. In any case, worse from the purchase of solid carrier will not be. Energy-efficient technology will achieve a larger time of work from one charging, the absence of high voltage circuits minimizes the risk of a non-refundable output of the disk under the BP breakdown, and the memory capacity in the portable PC does not play such an important role as in the desktop.

As for the smaller work resource, experience service centers Shows: The hard disk of the laptop fails and is subjected to premature wear several times more often and faster than in stationary computer. This is, first of all, with significantly large quantities Dynamic loads that are subject to the device during transportation and operation. Randomly dropping the laptop from the knee at the moment when the data is recorded on the HDD, the risk of output is out of order, even if the computer has not been visually damaged. Therefore, the probability is high that SSD will last even more than the railway.

Why ssd disc in Gamer PC

Gamers are the main ones this moment, part of SSD buyers. The use of a solid-state drive allows them to achieve better performance in three-dimensional games By reducing the time of their launch. Uploading levels, inventory, surrounding objects and other elements of the game world from files stored on the disk, also occurs significantly (up to 10 times) faster.

Nice difference in "seamless" games, such as Skyrim, Grand Theft Auto or Fallout. The inner world in them is located on one huge map, and to reduce downloads to iron in random access memory Only its part is stored. It can be the situation, for example, within a radius of 200 meters around the character. As the locality progresses, remote items from RAM are removed, and objects are recorded in the direction of which the player is approaching. Thus, reading from a hard disk occurs constantly and it is easy to guess that the data of the SSD processor will allow much faster and more efficient than the railway.

For gamers, the high cost of gigabyte in the solid-state drive is not critical, as the games occupy a relatively few space. If a collection of 100 films as FullHD weighs about 1 TB, the same Fallout 4 requires less than 50 GB of free space.

Why do you need a SSD hard drive in a multimedia computer

In the home PC used for web surfing and solving multimedia tasks (watching cinema, listening to music) SSD drive is needed least. The need for such a disk may experience only content connoisseurs as Blue-Ray. Wait for the film, a volume of 40 GB, will be recorded in PC memory, long enough (about 10 minutes). But for storing a favorite filing selection in FullHD, QHD or 4K UHD, spacious SSDs are required by 500, 1000 or 2000 GB. The cost of such drives exceeds a thousand dollars, and not everyone may afford this acquisition.

For undemanding users of a large SSD PC in a multimedia computer without particular need. The possibilities of classical (magnetic) hard drives are sufficient to meet the needs of 99% of users. However, a small (by 64-128 GB) a solid-state drive used as a systematic carrier (for windows installations), I will not be superfluous. It will significantly increase the overall speed of the PC, reduce the noise level system Block and save electricity economy.

Solid-state drives (SSDs) are new and rapid and good alternative For HDD hard drives, but does he need you? Read on how we democated a solid-state drive. The last few years there is a noticeable increase in volume sSD release and lower prices (although it is certainly impossible to compare prices between SSD and traditional hard drives).

What is SSD? What ways do you win from the acquisition of a ssd disk? What do you need to do differently with SSD? Read on to find out all about solid drives.

What is a solid-state drive?

You may be difficult to believe, but solid-state drives are actually pretty old technology. Solid-state drives were for many decades in various forms, the most first were based on RAM and were quite expensive, and they were installed only appear in an ultra-high-class and super computers. In the 1990s, on the basis of flash drives made the first SSD, but they were again too expensive for the consumer market and were barely noticeable outside of specialized computer circles. During the 2000s, the price of flash memory continued to fall, and by the end of the decade, consumer solid storage devices appeared on the market of personal computers.

So, what is the solid-state drive? Here it is necessary to first allocate what is a traditional hard disk (HDD). Hard disk is a set of metal plates with ferromagnetic material, which rotate on the spindle. The record on the surface of the magnetic plates is carried out by a tiny mechanical handle (drive lever) with a very thin stale (head). The data is maintained by changing the polarity of magnetic bits on the surface of the plates. This, of course, is a bit more complicated, but it is enough to say that everything is done here by analogy of the automatic player of the records, his hand is looking for a track on the record, also the drive handle and the head of the hard disk are looking for data. When you want to write or read the data from magnetic hard Plate discs rotate, the hand is looking for, and finds the data. This is the same mechanical process, as it is digital.

Solid-state drives, on the contrary, do not have moving parts. Although the scale is different, and the area for storage on the HDD is much larger, and the solid-state drive is much more common with a simple portable flash drive than a mechanical hard disk (and, of course, much more than ever, with a tape recorder! ) The overwhelming majority of solid-state drives on the market - this flash nand Memory, the type of non-volatile memory that does not require electricity to save data (as opposed to RAM in your computer, which loses its saved data as only power is turned off). NAND also provides a significant increase in speed much more than mechanical hard drives, since the time spent wasted when the plates are spinning and not looking for the data is removed from the equation.

Comparison of solid-state drives with traditional hard drives

It is always good to know what solid-state drives are, but it is even more useful to compare them with traditional hard drives that you have been using for many years. Let's look at several key differences in the current comparison.

Spin-time: SSD drives do not have "spin" time; The drive does not have moving parts. Hard drives have different spin time (usually a few seconds); When you hear a click-whirrrrrr for a minute or two when the computer is loaded or when accessing rarely used files, you always hear the rotation of the hard disk.

Access time and data delays: Solid-state drives very quickly find data and, as a rule, is an order of magnitude 80-100 times faster than hard drives; Moving Mechanical Turning Plates and Data Search, so they can access data almost instantly. Fast search Data on hard drives prevents the physical movement of the anchors and the rotation of the plates.

Noise: SSD drives are silent; The lack of moving parts means no noise. Hard discs vary from rather quiet, to a very strong sound level.

Reliability: individual production issues aside (bad wheels, firmware, questions, etc.) SSD discs went ahead in terms of physical reliability. The vast majority of hard disk failures as a result mechanical damage; At some point after x tens of thousands of hours, the mechanical drive is simply wearing. In the sense of the read / write cycle of hard drives limited.

On the other hand, solid-state drives have a limited number of recording cycles. This limited number of recording cycles is the main issue to condemn solid drive drives, but the reality is such that the average computer user is unlikely to be able to make a lot of read and write cycles on SSD. Intel companies X25-M, for example, can handle 20 GB of data for 5 years without failures. How often do you erase and write down 20GB of data on the main disk on a daily basis?

In addition, SSD discs can be used further; When the NAND modules reached the end of their record cycles, they are only for reading. The disk then reads data from the damaged sector and rewrites it to new part disk. Apart from lightning or catastrophic lack of design, refusal SSD more Looks like "Old age, why the lomit in my bones!", and not on a sharp "boom! Bearings in HDD! " And his stop. You will have enough time for reserve copy Your data and to purchase a new disk.

Power consumption: SSD discs are consumed by 30-60% less energy than traditional hard drives. Savings of 6 or 10 watts seem to be not much, but during the year or two on a strongly used car everything converges.

Cost: SSD is not cheap. Traditional prices for hard disk fell about five cents per gigabytes of data. Hardwood drives are much cheaper than they were 10-20 years ago (when they were limited special computer systems), But they are still quite expensive. Depending on the size and model, you can expect to pay somewhere between $ 1.25- $ 2.00 per GB.

CARE FOR CREETING SSD Drive

In the operating system management, saving data, and interacting with your computer is the only difference that you will notice how the end user during the operation of the SSD disk is to increase the speed. When it comes to care of your disk, there are several rules that are crucial.

Do not defragment disk. Defragmentation is useless for SSD and reduces the duration of his life. Defragmentation is a technique that finds pieces of files and optimizes them placing hard drives on plates to reduce the search and wear time on the disk. SSD does not have plates and have almost instant search time. Their defragmentation eat more recording cycles. Default in Windows 7 defragmentation is disabled for SSD.

Disable indexing services: If your OS has any search, the tool is added as the index service, turn it off. Reading time on SSD fastYou don't really need to create a file index and the index index process itself will be slow on SSD.

Your OS should maintain trimming. The Trim command allows your OS to communicate with the SSD disk and tell it which blocks are no longer used. With this command, the performance on SSD will rapidly degrade. In this publication for Windows 7, Mac OS x 10.6.6.6+ and Linux with a kernel 2.6.33+, support tRIM command. And khaki registry and additional programs exist to change more early versions OS, such as Windows XP to semi-support the Trim command. Your SSD disc should be paired with a modern OS for maximum performance.

Leave a part of the disk empty. Check the specifications for your device, most manufacturers recommend keeping 10-20% empty. This empty space helps the alignment algorithm (they transmit data through the NAND module memory to minimize the total wear on the disk and provide a long service life and optimal characteristics drive). If you leave too few space, then alignment algorithms with time will lead to premature wear on the disk.

Media on the second disk: SSD drives expensive, so it makes no sense to store your massive media files on your road SSD drive. You can choose traditional hard drives 1 TB and use big additional disc (If possible) for storing large and static files (for example, movies, music collections and other multimedia files).

Interest in memory: compared with the costs of solid-state drives, RAM is cheap. The more RAM will be installed, the smaller the recording cycles on the disk. You can extend the life of your expensive SSD drive, ensuring that you have an adequate RAM in your system.

Solid drive for me?

At the moment you have a history lesson, a check-in comparison, and some tips for maintaining your SSD in excellent form, but do you need an SSD disc? Check all the appropriate options and prepare for the following:

Almost instant download time: You can go from a cold download to view web pages in seconds with SSD; In the same window, you could often get in more than a minute with a traditional hard disk.
Do you want to fast access For general applications and games: we have already spoken many times, but solid-state drives are ultra-speed.
You want a more quiet and less voracious computer: as emphasized above, SSD drives are silent and consume significantly less energy.
You can use two discs: one for OS and one for files: If you store only a few family photos and CD-RIP or two, you will need more affordable traditional HDD to store large files.
You are ready to pay a significant amount for the SSD drive: this is the biggest amount for gigabytes today, but also time the performance increase is huge in 3000%.
If your list looks more complete than empty, and you want to get speed when working, then SSD is for you!
