I have 2 drobos for work, and really love 'em, but I need to buy like 3 separate external enclosures that can hold at least two drives per enclosure with RAID and FW800 support for the home and I don't want to spend DROBO money. Any suggestions? There are so many options out there that I'm a bit overwhelmed. I already have a bunch of 1TB drives, so I only need the enclosures.
