Many computer users have excess files that they would rather keep somewhere else, that’s where this device comes in handy because it uses any old hard drive that you happen to get your hands on.
All you need to do is connect the device to the USB port and then connect the hard drive, these can either be 1.8”, 2.5” or 3.5” or if your are feeling adventurous then you can always add a SATA drive.
