The reasons for formatting an SSD drive are always different. Something could go wrong due to virus infection or damage to media parts. Or maybe it is completely new, and this procedure is necessary in order to start using it successfully. One way or another, there are several ways to format an SSD hard drive.
This article will cover the most basic of them.
For what?
It was previously said that there are a lot of reasons for formatting an SSD. Each user may have their own unique case. However, it is also worth noting the most common options for what purpose it is necessary to format an SSD, new or old. Here is their list:
- in order to create markup. To be able to work with the hard drive in the future. The process is performed after the drive has been first attached to the computer. If formatting is not performed, the SSD will not be displayed among other local media;
- complete cleaning of accumulated debris. This procedure helps to clean the device from all those files that have accumulated on it over the years. If Windows is installed on the disk (for example), this will help increase the speed of the computer;
- the need to install an operating system. Best Option for the maximum on the new OS, it will be set to absolutely blank disk;
- elimination of errors and malfunctions. If the device is infected with viruses that cannot be removed, then it is worth resorting to the formatting procedure.
What types exist?
On this moment There are two options on how to format an SSD on Windows 10 or another operating system. Here are the ways:
- quick formatting. From the name it becomes clear that such a procedure does not take much time from the user. However, this form has big disadvantages. The fast option does not provide for optimization. All existing files are not deleted anywhere. And in the event that any errors or malfunctions occurred in the operation of the SSD, they will not be fixed;
- full formatting. The method helps to optimize the disk. During the complete cleaning procedure, complete removal files. The system is checked, and all detected violations, malfunctions and errors are corrected.
Now it’s worth moving on to the instructions on how to properly format an SSD.
Working on Windows 7
This version operating system from Microsoft is still almost the most popular. And it still has quite a large number of users. Therefore, you should not deprive her of attention. Let's take a look at two ways to format an SSD under Windows 7.
Easy option
In this case, only those tools that are originally installed in the operating system itself are needed. To format in this way, just follow the instructions:
- launch the My Computer program using a shortcut or explorer;
- among the list of drives connected to the device, find the required SSD;
- right-click on it to open the context menu;
- select "Format" from the list of actions;
- a window will open. Before formatting an SSD drive, you need to set some parameters. In the event that you do not know how and what to change, just leave all the items untouched;
- after setting, you can start the procedure.
Complicated version
This way to format a new SSD (or old one) suggests using administration. The procedure is carried out as follows:
- by activating the "Start" menu, launch the "Control Panel";
- here you need to find a section called "System and Security";
- in it go to "Administration";
- now double-click on the computer control item;
- in the left part of the window, find and activate the paragraph "Disk Management";
- after opening the list, select the one you need to format. Click on it right click mouse and start the corresponding process in the context menu;
- The settings window will reappear in front of you. Parameter values can be changed. But if you are not sure, then just leave it as it is;
- press the button to start the procedure and just wait for it to finish.
Now let's figure out how to format an SSD through BIOS.
Working with BIOS
To perform the formatting procedure in this way, you must resort to the help of third-party software. Among the variety of specialized programs, you can stop your attention on a utility called Acronics Disk Director. Let's use her example to format an SSD through the BIOS:
- First you need to install this software on a disk or USB flash drive. After that, connect the media and restart the computer;
- when starting the system, quickly press the BIOS start key. It should be kept in mind that for each motherboard comes your set. But in some cases, the desired key is written on start screen, at the bottom;
- then the BIOS menu will open in front of you. Using the keyboard, find and activate the tab called Boot;
- after that, bring the media with the installed utility to the first position. The drive to be formatted must be on the second or third line;
- now press the F10 button. The program will exit with saving all changes;
- then restart your computer. If all the steps above are performed correctly, the media with the installed software. In this case, you can proceed to the formatting procedure;
- select full version Acronics Disk Manager. After opening the window, before formatting the SSD, put a marker in front of the item with the activation of manual mode;
- then mark the required disk;
- select a format operation from the list on the left. A window with settings will appear. You can leave everything as default or change as needed;
- confirm your changes. Click on the checkbox located in the top bar of the window. And click on the "Proceed" button, thereby starting the formatting process.
Now let's look at the method of how to format an SSD using the command line.
Pretty risky option.
It is worth noting that formatting through the command line, as well as working with the registry editor, is a rather risky way. Making the wrong changes can cause the system to either hang or stop working altogether. So a further example of how it can be implemented by you at your own peril and risk:
- press the "Start" key;
- after that go to the section of all programs;
- open the folder there standard applications and select the "Run" command;
- now type cmd and Ok;
- this will open a command prompt window. Find a line that will end with the phrase format;
- here enter your drive letter followed by a colon. Press the enter button;
- you will be shown a warning message that all information and files will be permanently destroyed;
- it will also be necessary to agree to the beginning of the formatting procedure by entering the letter Y.
A little about the procedure
It is worth noting that the methods for formatting an SSD on the latest version of the operating system from Microsoft do not differ much from those that were given to work on the seventh release. Next, some of the most common options for how to format on the last page will be demonstrated. Windows versions.
This computer
This is the shortest and easiest way. In fact, it can be called formatting directly. This is done as follows:
- launch the program "This PC". Use a shortcut or "Explorer";
- from the list of connected media, select the one you want to format. Click on it with the right mouse button;
- in the context menu that opens, select the formatting function;
- after that, the already familiar settings window will open. Everything is the same here, if you are not sure, leave all the default items;
- press the button to start the procedure and just wait for it to finish.
Disk Management
- through the search bar, launch the "Control Panel" application. Among all the elements, find the administration section;
- after the transition, find the computer management section;
- on the left, find the paragraph called "Disk Management". Here, find the required device and, by selecting it, launch the formatting window. Carry out the parameter setting and activate the procedure.
Now let's talk about how to format an SSD if it is external drive.
Formatting an external drive
This version of the procedure is not too complicated, but it involves working with disk volumes. To format SSD data way, you need to do the following:
- through the start menu, launch the section standard programs. There, activate "Run";
- in the window that appears, enter compmgmt.msc and confirm your action;
- The Computer Management program will open in front of you. On the left side, open the disk management section. Determine the required disk in the pop-up subroutine;
- now activate the MBR and confirm the changes made again;
- right-click on the media and select the option to create a new volume. The "Wizard Assistant" will be activated. Here click the "Next" button;
- leave the size option at the value that is already set (maximum);
- in the next step, select the letter that will be called the drive. Confirm the action and continue the setup;
- a new window will open in front of you. There will be a section formatting string. Enter the drive letter in it and start the formatting process.
Quick Format
A flash-based drive called an SSD is good for everyone. High read/write speed, no moving parts, instantaneous Windows boot. But it also has its own Achilles' heel - a limited resource of rewriting cycles. Hence the following five important points.
Instruction
Do not use defragmentation on this drive! Defragmenting this type of disk does not help in any way, since they do not have moving magnetic heads. Reading from blocks scattered over different parts of the disk does not entail a decrease in the speed of work.
Moreover, defragmentation is even harmful to the SSD, as it wastes an already limited rewriting resource for nothing.
Do not use this drive to store files that change frequently. Due to the limited rewriting resource, it is harmful for this disk to store frequently overwritten files. Try to send the swap file, temporary files directory and browser cache to the disk of a conventional magnetic system.
Do not fill the SSD more than 75% capacity. Numerous tests by various experts have shown that above this mark, the speed of the disk decreases sharply. The reason is that if the SSD has a lot free space, then there are many free blocks. And writing to free blocks is much faster than writing to partially occupied ones.
A lot of free space - a lot of free blocks, and the write speed is higher. There is little space - many partially filled blocks, and the write speed is lower.
Don't store large, infrequently needed files like movies and music on the SSD. You won't get any win during playback, and valuable disk space is taken. If possible, store movies on another drive or external drive. If not, then delete them immediately after viewing.
An SSD only works effectively on newer operating systems released in the last 3 years. These are Windows 7 and 8.1, fresh builds of Linux. On older systems, you won't get good results.
note
From all of the above, it follows that best use SSD - use as a system drive. It also copes with other functions, but on a par with the disks of a conventional magnetic system.
Solid state drives SSD (eng. SSD, Solid State Drive or Solid State Disk) have been on sale for a long time. Their prices have become affordable for the vast majority of users. SSDs are fast, quiet, and consume less power. But ordinary users there are many questions about their maintenance, such as whether it is possible to format an SSD.
Why format a drive?
In order for the operating system to be able to use the drive to store files and install programs, it must be formatted. Formatting is the process of partitioning a disk, creating a master boot record with partition table. If you bought a new SSD, then formatting it is not only possible, but also necessary, because without partitioning, installing and reinstalling the operating system is impossible. In this case, the distribution kit of the operating system takes over the function of formatting the disk. As you can see, there is not a word about deleting data. Formatting only allows the system to work with the disk and the data on it. An example of formatting without deleting data can be given: changing the file system from HFS + to APFS with iOS 10.3 firmware - the file system changes, but the data remains unchanged. However, this is a special case. OS Windows formatting implies complete cleaning disk or its partition from data.
Formatting to delete data
The term "format" is often used to refer to the process of deleting data from a disk partition.
Quick Format happens in a few seconds. In this case, the boot sector and an empty file system table (for example, NTFS) are written to the drive, and the space on the disk is marked as unused. Data is not deleted. After a quick format, data on the HDD can be restored with special programs.
Full formatting involves rewriting boot sector and an empty table of the file system, as well as zeros are written to all sectors of the disk, bad sectors are marked, which are not used for writing data in the future.
With quick format SSD system uses TRIM command: The SSD controller overwrites all data on the drive and re-creates the sector list. In fact, for an SSD, a quick format is the same as for an HDD - full.
Full formatting an SSD is meaningless (after all, a quick format erases everything), and this can even harm the SSD - it will slow down its speed. Why is this happening? The principles of operation of HDD and SSD are very different: in the case of solid state drives, writing zeros to all cells will mean that the cells are not empty - they are occupied by zeros. Therefore, before writing anything to the cells, the SSD controller will first have to remove zeros, and then write new information there. And this greatly reduces the speed of the SSD.
Thus, it is necessary to format the SSD before installing the operating system, and to delete data from the SSD, use a quick format.
This article will focus on formatting a hard various systems. We will get acquainted with the concept of formatting, why is it needed at all, and in what ways can this be achieved? Well, friends, let's get started. Let it be known to you that formatting a disk is a useful and necessary thing. In fact, this is a process in which the hard drive is divided into logical disks for data storage. In the course of such actions, information occupies a certain place on disk sectors. And after formatting, programs that request access from the hard drive to this or that information receive an exact answer about its location. This process is also actively used in case of need to change file system to FAT32, NTFS, or exFAT. Advanced users know exactly how to properly format a hard drive, because this operation helps to reinstall already existing system, or install a completely new one, as well as destroy viruses that have deeply embedded in the hard drive. So, let's talk about how hard drives are formatted in the Windows operating system.
How to format a drive with Windows 7?
For formatting, several methods are used. Each of them has both advantages and disadvantages. Let's take a closer look at the main ones.
by the most in a simple way Formatting a hard drive is considered a method using operating system tools. To apply this method, follow the following algorithm of actions:
- Open "Computer" located on the desktop;
- On the disk that you plan to format, right-click and select "Format ...";
- Next, a window opens, in it you should select desired parameters and click on the "Start" button. If you do not know what parameters you should best set, then leave everything as it is, that is, by default.
There is another simple formatting method using administration. So, repeat everything in this sequence:
- Open the "Control Panel" by first clicking "Start";
- Next, go to the "System and Security" item, select "Administration";
- Double-click to open "Computer Management";
- In the left part of the window that opens, we find "Disk Management";
- Well, then, on the disk selected for formatting, right-click on "Format ...";
- In the window that opens, with formatting settings, you can choose the parameters yourself, or you can leave the default.
- Next, click on the "Start" button.
How to format a hard drive through bios?
To format the hard drive in this way you need help third party programs. Today there are many similar programs, but we will consider a program that is considered one of the best and which is very easy to work with, this program is called Acronis Disk Director.
Before you start hard formatting disk via BIOS, you need to have a bootable disk or flash drive with the Acronis Disk Director program.
How to format hard drive via command line?
So, let's go straight to the action:
How to format correctly?
Before proceeding with the description of formatting an SSD, we will tell you a little about what an SSD is. This solid state drive information that does not have mechanical elements, the work of which is based on the functioning of microcircuits.
Now let's look at how such media is formatted if the SSD is an external drive:
- First of all, click "Start" and follow the "All Programs" section, in which we select the "Standard" folder, and then "Run";
- In this window, enter the command compmgmt.msc and click "OK";
- The "Computer Management" window will appear, select "Disk Management" on the left side of it, a pop-up window appears asking for a definition SSD drive;
- Next, select MBR (Master Boot Record) and click "OK";
- Right-click on the container and select "Create a new volume";
- “Wizard Assistant” will appear, follow “Next”;
- Leave the “Specify Volume Size” option unchanged (maximum) and click “Continue”;
- Select the drive letter and click "Next";
- A window appears, where in the line "Format Partitions" we write the name of the disk and click "Next".
How to format a drive with Windows 10?
There are several ways to format a Windows 10 hard drive. In principle, this procedure is similar to formatting with Windows 7 installed. Let's take a quick look at how to do this in version 10.
So, the easiest way is using "My Computer":
- Open "Computer" and right-click on "Format ...";
- In the window that opens, select the desired parameters or leave them as default and start the process by clicking on the "Start" button.
Consider the second method, using the Windows Disk Management tool:
- Click "Start", open the "Control Panel", follow the item "System and Security", select "Administrative Tools", and then "Computer Management";
- In the left part of the window we find "Disk Management";
- Right-click on the disk that you want to format and select "Format ...";
- Select options and start formatting.
Another way, using the command line:
- We follow this path: “Start”, select “All Programs”, open the “Standard” folder, and, finally, “Run”;
- In the line we write cmd and press "Enter";
- IN command line write format and the letter of the drive that we will format, for example format e:
Well, you can also format the hard drive using the BIOS, we talked about this above.
Since the advent of solid state drives (Solid State Drive - SSD) on the market, quite a long time has passed. Prices for this product are gradually decreasing, making it more affordable, and now a 120 GB drive will cost about 4 thousand rubles. In fact, if you're looking to upgrade your PC now, then buying an SSD is one of the most cost effective options out there. You don't have to throw away the existing HDD(it will only partially change its function, becoming a storage of media and other heavy files), and computer performance in almost all operating modes will increase noticeably.
Users who are not particularly interested in the world of iron may not clearly understand the fundamental difference between an SSD and a conventional magnetic hard drive. HDD, and often the novelty is seen by them as the same HDD, only faster, smaller, lighter and more expensive. It is a misunderstanding of the fundamental differences in the operation of HDD and SSD that can lead to incorrect use of SSD, which in especially difficult cases will reduce all its advantages to zero. Yes, a solid state drive needs to be used correctly, but do not be afraid - the user does not need any painstaking daily deep technical actions. Rather, it is required of it to just not do a few simple things, and today we present a list of "not" for anyone who decides to screw their workhorse with a nimble SSD.
We ask the techies who see the captaincy here to take into account the fact that if you know all this, then you probably know the fact that there are other people who may not know all this. Replace the usual "thank you cap" with your additional advice, together we will make the Internet more useful.
Don't defrag
No need to defragment the SSD. If in old Windows with FAT32, you carried out defragmentation by inertia (although the same NTFS feels great without it), then with the purchase of an SSD, you can and should forget about defragmentation (the SSD itself) altogether.
SSDs have a limited number of write cycles (as a rule, the cheaper the disk, the less resource it has), and such shoveling of its contents will definitely not benefit the lifespan. Yes, recent SSD models have a very large reserve of write cycles, and you are unlikely to reach the limit when the disk stops working correctly, even with frequent writes, but the point here is rather that defragmentation itself is meaningless for SSD.
The HDD uses mechanical parts. The read head wanders back and forth across the surface magnetic disk. Accordingly, the more specific data is scattered on the disk, the more movements and time it needs to fully read this data. Nothing moves in an SSD, and access to any memory cell is equally fast and does not depend on the relative position of this data.
Don't Format
We are used to the fact that in order to completely and permanently delete data from the HDD, it is necessary to use additional tools: formatting, special utilities like DBAN or the Wiper tool, which is part of CCleaner. This is done so that a cunning attacker cannot recover the data you deleted from the disk using a utility like Recuva.
In the case of an SSD, things are different. The point here is not even in the drive itself, but in the operating system. If you are using a more or less up-to-date OS (Windows 7+, Mac OS X 10.6.8+, Linux with Linux kernel 2.6.28+), then the system takes over the final deletion of data from the disk, and it does it automatically using the TRIM function.
TRIM implements the ability for the OS to "inform" the SSD that the file is completely deleted and that the sectors occupied by it need to be cleared. Some of the early SSD models didn't support TRIM, but that was so long ago (and those SSDs were so expensive) that the chances of hitting that drive model are close to zero.
Do not use Windows XP and Windows Vista
A new toy - a new AXIS! And this is not at all new. It's just that XP and Vista don't support TRIM. In the previous paragraph, we gave the concept of TRIM, and now we need to explain how the absence of this feature affects the SSD. If there is no TRIM, then after deleting the file, the data will still remain on the disk. As a result, when information is written to the same sectors again, they will first have to be cleared, and only then data will be written to them. Unnecessary untimely operations -> speed reduction.
On modern operating systems, TRIM is enabled by default. The user doesn't have to do anything. Just leave everything as it is and enjoy the speeds of the SSD.
Don't beat yourself up
In order for an SSD to operate at full speed, it needs to maintain an amount of free space on it of approximately 25%. It sounds a little dishonest: you buy an expensive SSD, there is already so little space in it, the system sees less space in it than it is written on the box, and then they also ask you to leave a quarter of the volume in reserve? Unfortunately yes. This is a feature of the SSD, and so far we do not have the best widely available technologies. You have to accept the rules for the sake of the best speed.
From the point of view of internal processes, the performance drop with a small amount of free space is explained as follows: a lot of free space - a lot of free blocks. When a file is written, data is written to free blocks. Little free space - many partially filled blocks and few completely free blocks. When writing a file, the system will first have to read the partially filled block into the cache, add new data to it, and then write the already modified block back to disk. And so for each block.
The limit of 25% is not taken from the ceiling. This indicator was reached by the guys from AnandTech, who conducted research on the dependence of SSD performance on its occupancy.
In fact, if you use the SSD exactly where it is strongest, then the need to leave a quarter of the space free will not bother you. Now we will just talk about the role in which the SSD is most effective.
Do not use as storage
Buying an SSD to store your music and movie library on is a bad idea. HDD speeds are quite enough to comfortably record and watch a FullHD movie from them, and listen to Losless music. An SSD is needed where access and write speed is most important.
The SSD must be used as system disk. It should have an operating system, applications and, if absolutely necessary, modern games. Nothing else.
With the understanding that the SSD ideally serves as a catalyst for the most demanding processes for the fast operation of a computer (OS operation is the basis of everything and everything, fast work important applications, fast reading of data from the "body" of the game), there is no need to hammer it to capacity. An SSD is a dedicated fast lane for only the most important.
If you still want to use a fast SSD as storage, then just calculate the cost of rubles per gigabyte of memory for it and for the HDD.
What if you bought a fancy new ultrabook that only has an SSD, but you want to record movies? Buy an external hard drive with a USB 3.0 or Thunderbolt interface (provided that this standard is supported by the beech itself).
We hope that this information will help you start using your SSD for its intended purpose and to get the most out of it.
The problem of improper formatting of SSD drives has been discussed many times since these drives entered mass production. And although modern operating rooms Windows systems have already learned how to work with solid state drives correctly, when formatting drives with third-party utilities (or in Windows XP), there may be performance problems, which will be discussed below.
The reason for conducting tests and writing material was not only the desire to personally verify the result, but also, to a greater extent, the need to get specific numbers, since too many Internet resources, when describing a problem, instead of accurate data on performance changes, give vague wording and refer to other articles, which, in turn, are sent somewhere else. In the end, after finding some negative feedback about the impact of partition alignment on SSD performance, it became clear that the situation needed to be sorted out on our own. The material contains theoretical basis and a guide to verifying the correct partition shift on an SSD, as well as performance tests.
A bit of theory
Modern drives are presented to the operating system and programs in the form of memory divided into sectors of 512 bytes, however, at the physical level, the size of each sector of the disk is 8 times larger and is 4 KB. To maintain compatibility with older applications, another layer is created above all this, in which each sector is also equal to 4 KB. OS Microsoft released before Windows Vista, reserve the first 63 sectors at the beginning of the disk for the MBR (master boot record), and this leads to the fact that the logical (topmost) and physical (lowest) layers of the drive are shifted relative to each other, and therefore, one logical sector is placed immediately on two physical. It follows from this that all I / O operations will be performed twice, which not only reduces the performance of the SSD, but also consumes its resource faster (as you know, SSDs have a limited number of write cycles). As you might guess, in order for the sectors at the physical and logical levels to match, the shift at the very beginning of the disk must be a multiple of 4 KB (4096 bytes).
How to know if a partition is shifted correctly on an SSD
As mentioned above, modern systems Windows knows how to correctly shift partitions when formatting, however, if the initial breakdown was done in third party utility or in Windows XP, then even reformatting in Windows 7 will not fix the situation. In this case, either the complete removal of the partition (s) and the creation of a new one, or the shift of the entire disk area using special utilities.
To find out if you need to do all this at all, you need to run the msinfo32 utility, go to the Components->Storage->Disks section (Components->Storage Devices->Disks), and find the Partition Starting Offset value for your SSD drive. 
If this value is not an integer when divided by 4096, then the first section is not shifted correctly. In our case, 32256/4096 = 7.875, which is to be expected after formatting the disk under Windows XP.
An alternative way to get the same information is to run the following command on the command line:
wmic partition get BlockSize, StartingOffset, Name, Index
As you can see, on one drive (SSD in our case), the first partition is shifted incorrectly, and on the second (HDD) it is shifted correctly, since 1048576/4096 = 256 (an integer).
How to move a section
If nothing important is stored on the disk, then the fastest way to fix the error is to delete all partitions and create them again from under Windows Vista / 7. Simple formatting is indispensable here, since the area shift does not occur.
If the disk is bootable and the operations described above are undesirable, then you should start shifting the partition. Let's see how this is done using free utility GParted.
1
. GParted bootable ISO disk (115 MB) or use one of the Linux distributions, in which GParted can be available as a separate utility.
2
. We burn the image to a CD or USB flash drive and boot from the media.
3
. We select the first partition of the SSD drive in GParted and the Resize / Move command.
4
. Uncheck Round to cylinders, put "2" next to Free space preceding, click Resize/Move and then Apply.
5
. We repeat the previous paragraph, but instead of "2" in Free space preceding we put "1". Click Resize/Move and then Apply.
6
. If there are several partitions on the SSD, then steps 3-5 must be repeated with each of them, which can take several hours.
GParted performs a shift operation without deleting data, however, when working with hard drives, it is always recommended to save important files to another medium.
After a reboot, the system will most likely refuse to start, but Windows health can be quickly restored using the Repair Your Computer command in the first dialog of any boot disk with Windows 7.
After the appearance of the Desktop, we check the correctness of the alignment in Msinfo32: 
2 097 152 / 4096 = 512 - the section is shifted correctly.
Performance
Before directly measuring the performance, an attempt was made to count the input / output operations before and after formatting the disk. According to Microsoft help, the I/O Reads and I/O Writes options in the Dispatcher Windows Tasks show the number of corresponding reads or writes for each particular process.
Five times before using GParted and five times after, the same 700 MB ISO file was copied to the SSD using file manager Altap Salamander. In each case, the number of reads and writes was exactly 22.3 thousand. The lack of difference is most likely due to the fact that the Windows Task Manager only works with top level disk and does not know how to display the actual number of operations at a basic level.
HD Tune and Crystal Disk Mark were used to directly measure performance. The Kingston HyperX SH100S3B/240G SSD was first tested on a computer with SATA 2.0, and then on a platform with SATA 3.0 support, where it managed to reach its full potential: the speed of the drive is at the level of 500+ MB / s, but when using SATA 2.0 it rests at 200+ MB/s. All measurements were taken 5 times, and the size of the test file in CrystalDiskMark was 1000 MB.
In HD Tune's Benchmark mode, only read speed was measured, since writing tests required deleting all partitions from the disk (for the utility to directly access the drive), and this, of course, made the whole test meaningless.
SATA 2.0
It would be logical to assume that a drive whose performance is 2.5 times higher than throughput SATA 2.0 will simply run into interface capabilities and will not show any growth on an outdated platform, but this turned out not to be the case at all. Growth, and quite significant, was recorded even in this configuration of the test system.
As you can clearly see in the diagram, the read speed in SATA 2.0 mode remained practically unchanged, and the bottleneck of the interface became the determining factor here (with the exception of the last two tests with small block sizes).
A completely different picture emerges in the write speed tests, where in each case an obvious difference in performance was recorded. The minimum increase in productivity was 12%, and the maximum - 450%.
SATA 3.0
This mode made it possible to reveal the full potential of the drive, and in tests it demonstrated exactly the speeds that the manufacturer indicated on the box (about 500 MB / s in read and write mode).
The reading check again did not bring much sensation, except that HD Tune in Benchmarks mode seemed to correct for the result in the previous test, where instead of a slight increase in performance, a slight but still strange decrease in performance was recorded. The result of CrystalDiskMark (4K QD32) also stands out, where the difference in speed was not a couple of MB, as in other tests, but much more.
The write results are also very similar to those obtained in SATA 2.0 mode. The increase in each test (except the first and last) is almost identical, and this is easily explained by the fact that the SSD performance in these tests did not depend on the version SATA interface. If we make calculations, then the minimum increase was 18%, and the maximum - 310%.
Conclusion
The test results were somewhat unexpected. First, in theory, the performance of the drive should have increased during reading, but the obvious improvement in the tests was recorded only during write operations. Secondly, before the start of the test, much more modest growth rates were expected (if expected at all), but despite this, in some tests a 3-4-fold increase in write speed was obtained.
Since checking the correct partition shift on an SSD takes literally less than a minute, we recommend that all owners of such drives, just in case, check their solid state drive and, in case of incorrect formatting, configure it in the correct way to get maximum performance. Interestingly, the wrong offset is also relevant for conventional drives, and there is evidence that the negative impact of this factor manifests itself in R.A.I.D. arrays. Therefore, the owners of such data storage systems, especially those configured for top speed, and not on redundant security, it also makes sense to optimize your system.
