Any class 10 card will probably be perfectly fine, so long as it is a reputable brand with good reviews. The great thing is that prices for large capacity cards are becoming very affordable. I bought two 32GB sd cards, one for my 3ds for rxTools + emuNAND before moving into a9lh, and another for my wii u for loadiine (and other homebrew, if the wii u homebrew community grows at all)would you recommend to buy the SanDisk 32GB Ultra Micro SD HC Class 10 Memory Card for new 3ds.

Wii U homebrew does not support USB hard drives. I already have one, it's just that I can't use loadiine with it (or any other homebrew). I'm talking about Wii U homebrew, not vWii homebrew or standard Wii U applications.for the wiiu you should just buy a tb hard drive since it does not only support sd
