Really good value. The USB 3.0 allows almost double the performance (which are limited by the disk itself and not the usb 3.0) and 2.0 I stagnated at 25 mo / s. He is silent and does not heat which is a very good point. I would say its only weak point is the case of manufacturing quality that makes a little OCD. But good for the price ... and then I never had any problems since I have so I highly recommend it.
