Test Procedure

In an effort to really stress the flash SSDs, we ran the following cycle on all drives:

1st cycle

  • h2benchw sequential read/write test
  • IOMeter fileserver, database, webserver, workstation profile I/O test

2nd cycle

  • h2benchw sequential read/write test
  • IOMeter fileserver, database, webserver, workstation profile I/O test

3rd cycle

  • h2benchw sequential read/write test
  • IOMeter fileserver, database, webserver, workstation profile I/O test

4th cycle

  • h2benchw sequential read/write test

5th cycle

  • h2benchw sequential read/write test

6th cycle

  • h2benchw sequential read/write test

We decided to run the sequential h2benchw test and immediately switch to I/O loads three times in a row, so the drives would have to switch from maximum throughput to maximum I/O performance repeatedly. Then we ran three additional h2benchw tests to see if and when the flash SSDs returned to their initial performance levels.
