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
• HD-LB2.0TU3-EU

Be sure to keep your drive up to date with the latest firmware. When updating the drive's firmware, do not select to format the device if prompted by your PC as this will delete your data. You will be able to update the firmware without formatting the device.

For information about updating the drive's firmware, please visit the manufacturer's website.
