Compatible USB storage devices

You can expand the amount of available storage space with external USB storage devices.
Nintendo recommends using self-powered hard disk drives, i.e. devices that use an external power supply instead of drawing power through USB. Devices that draw their power from USB ports are known as "bus-powered" devices, and are not recommended for use with Wii U. For the best results with storage devices, we recommend using a hard drive with its own power supply that connects to the Wii U via the USB port on the console.
Please note that you cannot remove/connect a storage device while the power is on.
We have found that the following external storage devices work with Wii U; these devices have been subjected to basic performance tests:
Buffalo HD-LBU3 series
HD-LB1.0TU3-EU
