    One USB port will be plenty to power the drive and migrate any data. I'm currently using this model and it has no problems getting everything it needs from either the included USB 3.0 cable or included FireWire 800 cable.

  • Yes and No. It depends on which hard drive you select based on the RPM's. If you choose the hard drive with 5400 RPM you should be good to go, as it says it does have a usb bus.
