Speed is only one factor here. The device is also powered by the USB. My external SuperDrive actually has two separate USB 2 plugs, not for speed, but for enough power to run the device. USB 3 has more power and its more efficient. Playing a DVD consumes a lot of power from the plug, and would be much better with USB 3.
