So, I'm thinking about modding my Wii U after recently modding both my Wii and 3DS, but I'm not sure what kind of storage device I should use for storing the games, I know you need a SD Card for the homebrew stuff (gonna get a 64GB), But I'm not sure what to use for the Wii U games, I've been thinking of a USB drive, but people say it's not good, should I use HDD or something different? For anyone wondering, I'm gonna get something around 256GB.
