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 specified, and then read it. This records the speed of writing and reading from this drive. In addition, if in the process of writing or reading data loss or errors are detected, the program will notify you about it. This utility can give information about the amount of the drive under test, how many MB is damaged and how much is in working condition. I will write about the algorithm itself below, as well as 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. There is no curator in the subject. For questions about filling the caps, please contact the section moderators via the buttonunder the messages. How to do it right, what would you understand the first time, well describedhere. Post has been editedRamsteiner - 15.03.19, 02:27 |

Posted on 03/01/2012, 16:10: True, in everyday tasks the difference is not really felt. We must take the one who has more guarantee. And this is Intel and Plextor. |

Therefore, I must adhere to the list that I wrote above. How do I understand OCZ slag, then it is worth taking KINGSTON V200 SV200S37A / 64G? VERBATIM 47477, 64GB also does not inspire confidence, what about TRANSCEND? Post has been editedPahomov Kirill - 01.03.12, 16:50 -------------------- My glands1 |

Guru [offline] Group: Honorary Gameday Messages 17916 Check in: 10.04.10 Samsung Galaxy Note9 Exynos Reputation: 2686 | Pahomov KirillVertex - the first quarter of the 10th year on the very first sandforce, Kingston - the 4th of the 11th. The flush itself seems to be the same for them. These speeds are indicated at maximum, for compressible data under ideal conditions - "parrots", in the people. If the warranty is the same, I would prefer kingston. |
