Neat tool, Jens...


and I think it comes with a few example files. Here's the random write file that Jens suggested, and that works pretty well..

It first creates a 2GB file to do the IO on, then does random 4k writes to it with O_DIRECT.

If your SSD does badly at it, you'll just want to kill it, but it shows you how many MB/s it's doing (or, in the sucky case, how many kB/s).


heh, so far, the SSD is poking along...

Jobs: 1 (f=1): [w] [2.5% done] [ 0/ 282 kb/s] [eta 02h:24m:59s]
..

Try turning on the drive write cache? hdparm -W1
