I know there have been threads similar to this already, but I don't think that they reached a consensus. I would like to know what external Thunderbolt drives ACTUALLY can do Thunderbolt speeds. So far, I have seen the LaCie, the Buffalo and the Seagate (1 TB drives with TB + USB 3.0). It seems, however, that those are just USB 3.0 speeds with a Thunderbolt port. I have also seen the Pegasus J2 (I think), which IS thunderbolt speed, but is $400 for 256 GB. Anyone know any affordable fast options? I would like anywhere from 256 GB to 512 GB, but do not want to spend $1000 for an external drive to complement my SSD's storage (256). Thanks for all ideas.
