Noted, many times already. That's why I wrote "should be" - but in this special scenario (filesystem speed tests) I don't care for file integrity: if I pull the plug after "sync" and some data didn't make it to the disks, I'll only look if the testscript got all the timestamps and move on to the next test. I'm not testing for "filesystem integrity after someone pulls the plug" here. And remember, I'm doing "sync" for all the filesystems tested, so the comparison still stands.
