Best options for external RAID array? USB 3, bus powered?

[benguild]

I'm looking for something that I can plug into a USB3 or Thunderbolt (or Firewire with an adapter) on my rMBP and ideally mount a RAID-1 on my system.

I found this, but it needs an external power source.

Does anything exist that's kind of like what I'm describing? Most RAID enclosures are for 3.5" drives, which isn't a dealbreaker, but still.


Let me know, thanks! This would mostly be for reghosting a system that was lost or damaged when traveling. So, something redundant that wouldn't be easily corrupted is ideal

I've this one since a couple of years: http://eshop.macsales.com/shop/firewire/EliteALmini/RAID/eSATA_FW800_FW400_USB

Is USB 2, FW800 and ESata, unfortunately not USB 3 or TB. I use it with 2x 1TB in RAID 0 connected via FW and it doesn't need external power. Tested on MBP 2010, Latest Mac Min and rMBP.

I'be bought the enclosure only, without drives, that I've provided myself.
