Anecdotal - I have found "smart" raid controllers to fail more often
than dumb scsi controllers (or even SATA/PATA controllers), and some
seem more failure prone than semi-decent operating systems.
Not recommending people turn fsync off, but the O/S "always" exists,
if it is that flaky, you might lose data anyway, so pick a better O/S.
What's more likely in most places is somebody powering down the
server abruptly, and then fsync=off could hurt :).
