Don't think this is just paranoia, either. I've had it happen to me
SEVERAL times - either a second drive fails before I can replace the
first, or the second drive in a pair fails during rebuild onto the
replacement. I use regular RAID scrubbing, so this isn't just a case of
undetected media errors.
Nothing beats good backups.
