I'm working on a MacBook Air, which unfortunately only a 256GB SSD has it. But since I still need for my daily work now and then Windows, I've created a few virtual machines (VMware Fusion). And these VM's are on the new external drive. MAN is not noticed! Absolutely smooth working possible and these images have, after all, between 20 and 60 GB in the virtual environment.
So the board, I can only recommend. Would only be interesting to see how going under USB 3.0, after all, the Mac has only USB 2.0.
