Flashbench
In order to find out the erase block size of bundled 64GB SSD, SanDisk pSSD-P2, different tests were conducted using flashbench. All tests were ran under Linux Mint 11, booted from an USB flash:mint ~ # uname -a
Linux mint 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:50 UTC 2011 i686 i686 i386 GNU/Linux
The following are few offset test results:
 |
| Random write test with 16MB erase size |
 |
| Sequential write test with 16MB erase size |
 |
| Random write test with 32MB erase size |
 |
| Sequential write test with 32MB erase size |
Various tests were performed and showed the erase block size is 16MB. Thank you for the help and assistance from Arnd Bergmann, the coder of flashbench. Other figures are posted in Linaro.org.
