I read this recently elsewhere, and find it very hard to believe that two
drives -- even identical ones purchased at the same time -- would fail
essentially simultaneously.


Believe it, I see it plenty of times a year, usually with the same
reaction from the owners as you just had.

If it didn't happen why would there be companies specialising in data
recovery from failed RAID sets?

Don't forget if you have a mirror set it doesn't have to be a drive
failure, if your data gets corrupted you're still toast because the
corruption is faithfully mirrored too.

RAID is not a replacement for a good backup and your backup is only as
good as the last time you did a test restore.
