Overall, the drive itself is great. But the problem is the USB 3 port. It's poorly glued to the drive's board, so if the USB cable is connected to it and has a certain angle, this will put a force on the port that will eventually make it detach from the board.
So my advice is to either get another drive or be careful with the USB 3 port. Don't leave the USB cable connected to it while you carry it around and make sure the cable is parallel to the surface on which the drive is. The FireWire ports still work and seem well glued to the drive's board (to date).
