I've got the OWC ThunderBay 4, which I use for video editing, and I really would like to upgrade my old MacBook Pro to the new Retina MacBook, primarily for the portability. I know it can handle a pretty surprising workload in Final Cut Pro X, especially with the new hardware boost announced today, but I can't seem to figure out a method to use my external hard drives that only have Thunderbolt into a rMB. Any ideas?
