EDIT: Wait, maybe I'm wrong. I think I want to use redNAND (or IOSU?) for 100% game compatibility so does that mean I have to install games to USB storage? It looks like you can install Wii backups on either the internal NAND, USB drive, or SD card. Which is the fastest? It seems most convenient (but a bit expensive) to buy a 256 GB SD card and use that inside the Wii so you don't need an external drive or USB drive, but how is the speed? Also, can you use the SD card for both Wii and vWii game backups?
