I was going to go with RAID 1 using 2 TB drives. Got a line on 2TB
externals with longer than 1 year warranties (since buying drives
themselves comes with 3). At a cost difference of $150(Sheeva is about
$100, the ReadyNAS is $250) I don't see myself saving much buying cases
and drives.

That would also be 3 power plugs instead of one, and if I turn of the
computer controller will it turn off the usb drives? (I guess it would
if they are usb powered vs. their own power button).

What do you think about the RAID case for $50 I posted in the other part
of the thread? Seems to be the same as buying 2 reliable single drive cases?
