Hi, would you like to know what could be the best external hard drive for the Wii U? Here are some options: The 320GB hard drive from PDP I will choose this hard drive, because I don't need up to 1TB or more to store my games. The Buffalo mini station: avaiable in 500GB and 1TB The Hitachi (HGST) Touro Mobile avaiable in 500GB and 750GB The Toshiba Canvio Basics from 500GB to 1.5TB Well, there are some of the best external hard drives for the Wii U, but don't forget to use the USB Y-cable like this: To avoid power issues with the Wii U. Thanks!!
