Are all these External Drive good for the WiiU or not?

You can use USB 3.0 devices/sticks, although when using a usb hard drive (not a stick) you need to have an AC adapter or a second usb cable to power the device, because the Wii U won't let you use a HDD that uses one usb cable for power and data.

But a stick should be working no problem?
