I've bought quite a few digital games on my Wii U and the 32 GB storage is absolutely woeful. To make matters worse, the eShop insists that I have enough free space to BUY a game. Absolutely insane to think about this restriction.
At first, I figured I could use my spare micro SD with an SD card adapter as back up but apparently, it's only usable on Wii mode! What in the world?! I swear, sometimes, Nintendo tries hard to be incredibly dumb!
So, at the end, it looks like I will have to buy a USB hard drive with an AC adapter OR with a Y-cable to use the USB power. It seems that these drives have sleep modes if there isn't an independent source of power.
