It's small, easy to use & comes with a manual for easy set up for your Wii U.I got the 2TB model, though I probably won't need the extra space since I own most of my games physically but with DLC and update data as well as Virtual Console, my 32gb model soon ran out of space, so I wanted to be safe than sorry.The drive comes with it's own 3.1 Y-cable, so you don't need to buy one seperate unless you just prefer a particular brand. The cable it comes with is rather stiff but works just fine.It also comes with an external power supply AC adapter, but you don't need to use it if you are using both USB plugs on the Y-cable. It boots up automatically with the Wii U when powered on, or when it goes into sleep mode to update.It's so small & sleek, I just love how it looks next to the system. It's really neat. Couldn't ask for a better drive.
