Attention!


Huge base of SSD reviews
Information required to select SSD
    To select SSD you need to know:
  • Motherboard and processor model
  • Desired Drive Size
  • Desired Drive Form Factor
  • Purchase budget
  • The operating system to be installed on the SSD
  • Shop \ city for orientation in prices and assortment

Test flash memory SSD program H2testw
Instructions and description of the program H2testw
H2testw is a small but very useful program for testing the "quality" and speed characteristics of any type of flash drive. The essence of the H2testw program is that it can write a test file to the flash drive you specify, and then read it. In this case, the write and read speeds from this drive are recorded. In addition, if a data loss or error is detected during recording or reading, the program will notify you of this. This utility can provide information about the size of the drive being tested, how many MB are damaged and how much is in working condition. I will write about the algorithm of work below, and I will also give a decryption to the test results.

How to work with the English version of the program:
Download the archive and run the h2testw.exe file, then select the language “English” (or “Russian” if you downloaded the Russian version, but more about it later).
Next, select the test drive “Select target” and go to the “Data volume” item.
Here we select “all available space” - in order to test the entire drive in whole or “endless veryfy” and indicate the size of the recorded file in order to test the drive partially.
Then press “Write + Verify” to start the test of writing and reading, and if the flash drive has already been tested and there is a file, only “Verify” will be lit, which will perform the read operation and verify the integrity of the previously recorded file.
Next, an information window appears, in which we see general information about how to test the drive. We are shown the average write / read speed, the time until the end of the operation, and the overall progress bar.
At the end of the operation, we can get the following results:
Test finished without errors.
You can now delete the test files * .h2w or verify again.
Writing speed: 5.05 MByte / s
Reading speed: 11.4 MByte / s
H2testw v1.4
This result indicates that the test was successful. The average write speed to disk = 5.05 MByte / s, average read speed = 11.4 MByte / s.

Bad test result:
The media is likely to be defective.
1.8 GByte OK (3954734 sectors)
5.8 GByte DATA LOST (12240850 sectors)
Details: 2.9 GByte overwritten (6240208 sectors)
0 KByte slightly changed (2.8 GByte corrupted (6000642 sectors)
8 KByte aliased memory (16 sectors)
First error at offset: 0? 0000000000003830
Expected: 0? 358d089906064530
Found: 0? 158d089906064530
H2testw version 1.3
Writing speed: 2.53 MByte / s
Reading speed: 6.51 MByte / s
H2testw v1.4
Now we see that when testing a drive with a capacity of 8 GB, errors were found, of which only 1.8 GB is available for normal recording (1.8 GByte OK), and the remaining 5.8 GB (5.8 GByte DATA LOST) cannot be used, since memory is corrupted. The average speed for this storage medium = 2.53 MByte / s, the average read speed = 6.51 MByte / s

Another bad test result:
The media is likely to be defective.
0 KByte OK (0 sectors)
3.8 GByte DATA LOST (8030208 sectors)
Details: 327.7 MByte overwritten (671296 sectors)
0 KByte slightly changed (<8 bit / sector, 0 sectors)
3.5 GByte corrupted (7358912 sectors)
327.7 MByte aliased memory (671296 sectors)
First error at offset: 0x0000000000000000
Expected: 0x0000000000000000
Found: 0x000000000ffff000
H2testw version 1.3
Writing speed: 3.19 MByte / s
Reading speed: 0.99 MByte / s
H2testw v1.4
In this test result, it is written that this flash drive is not suitable for use, since it has an O KB of “living space” (0 KByte OK (0 sectors)) from a volume of 3.8 Gb.

Marvell has announced the massive introduction of the third-generation Marvell 88SS9187 SSD controller (replacing the previous 88SS9174 SATA 3.0 6Gb / s controller).
Attached Image
88SS9187 controller supports SATA 3.1 data transfer interface with 6Gb / s bandwidth.
Among the other distinctive features of the Marvell 88SS9187 SATA 3.1 6Gb / s 3rd generation SSD controller are:
- Better energy efficiency and lower cost,
- Up to 200MB / s read / write per channel
- Internal RAID for each NAND chip to optimize the disposal of a worn NAND block, block group, chip or the entire chip
- Support up to 1GB DDR3 DRAM cache
- The maximum possible sequential read speed for the 6Gb / s interface
- About 500MB / s sequential write speed even with a cluttered drive
- Best-in-class IOPS performance for arbitrary reading and writing with minimal reserved space and minimal performance degradation
- Supports On-chip RAID technology and low power consumption


Well-known SSD manufacturers (Intel, Crucial, Corsair and Plextor should be assumed) intend to immediately use the new controller in their solutions. Additional partners will join later this year.

Rep: (55)
And why sometimes drives with lower speed characteristics are several times more expensive than higher speed ones? For example, the first SSDSC2CW120A310 and SSDSC2MH120A2K5 have read / write / iops write speed of 550/500/40000 for the second 210/450/8000, but the second is several thousand more expensive .. because of the difference in power consumption?

One on the proven Marvelle (?), The other on the widespread Sanfors (whose speeds are, in fact, “corn” - get out through the post above the article). Well, they have flash for various technical processes.

But does it make sense to put ssd (for example, crucial m4) if the mother does not support sata3? Will there be a noticeable increase in speed if everything now turns on a terabyte blue series screw?

There will be a noticeable increase in speed

The most "progressive" parameter in SSDs is access time. You can measure your bleu terabyte, for comparison.

regarding intel 320series

It’s already old, and besides, the speed is 2 times lower than previously proposed, if the price is not 2 times lower, I don’t see the point in them. The 330 series seems to be nothing, but I haven’t seen reviews on them yet, and I haven’t been looking, to be honest, as long as I have two leaders and I have enough of them.
