Thinking about the same. Just worried about Seagate reliability, but I suppose that RAID 1 will take care of that.
I haven't seen many terrible reports on the drive that's inside this enclosure.
Yeah, a Raid 1 of these would mean that I would literally have to lose 4 drives total to lose important drives. The Raid 5 would have to lose two drives and both 4TB would have to fail.
I guess a horrible power surge could do it, but that's a chance everyone takes.
