This case is excellent and it really is usb 3.0. I tested it out with a 2012 macbook air and i used a western digital 500 gb laptop hard drive that i was no longer using. It is fully aluminum and your hard drive is directly in contact with the inside of the case, so i would not recommend dropping this as there are no rubber bumpers to absorb shock. It is very compact and simple to use, the usb 3.0 cable is thick, sturdy, and is long enough. It comes with some screws and a tool to mount the drive. The plastic feels a little cheap, but i have not had any problems. It looks nice next to other portable hard drives and i'm considering upgrading my other ones with this enclosure. I highly recommended for its value, ease-of-use, and speed.
