I'm looking for a raid based hard drive array for local storage. I'm happy with USB 3.0 speeds, and wouldn't be able to take advantage of thunderbolt anyway due to being on a rMBP with two screens attached to the thunderbolt ports (cant use HDMI due to it being flawed on this machine). What I want is either a 2 or 4 drive enclosure. If 2 drives, it should support RAID1, and if 4 drives, RAID 10. I know OSX can probably handle this, but if its baked in to the enclosure, that's a bonus. I know there are a number of these out there, just wondering which ones people would recommend, and why.
