You mention a pair of 1.5T drives.  I would guess that they are
Seagates since until recently that was the only brand of 1.5T drives
(I think).

The Seagate 1.5T disk drives (in fact all 7200.11 seagate drives) seem
to be having problems that have got many owners picking up pitch forks
and torches.

One of the symptoms that is recurring is that drives drop out of RAID
arrays causing them to be rebuilt.  A reboot seems to fix the drives.

I've been pushing for more useful problem reports but have not
succeeded.

The grand-daddy of thread on this is at
  http://forums.seagate.com/stx/board/message?board.id=ata_drives&thread.id=9060
Unfortunately many things are mixed together in this thread.

One of the odd things about the Seagate forum is that Seagare techs
never post there.  There are Seagate admins who know nothing and admit
it and there are users.

BTW, RAID is not a good solution to the backup problem.  Too many disk
threats are correlated when the drives are spinning in the same box
and run off the same OS/controller/power-supply.  Think of fire,
lightning, flood, or theft.  Oh, and ordinary file deletion, probably
the most common problem.
