What drives are by the way the best consumer grade drives to use for
RAID operation?

I've had good luck with Hitachi (used to be IBM) and Samsung lately,
more so than WD. Hitachi's 5-year warranty (everyone else here being
only 3) is also an indicator. . .

WD15EARS drives) was dropped from the array due to powerfailure and
rebuild failed because of bad sectors on another drive. I have been

Sorry I can't help more but with any such large drives I'd suggest
sticking with RAID6, plus hot spares if you think you might not notice
and/or be able to quickly replace a failing member.
