USB storage devices should mostly all work.


Speed: USB transfer speeds can be faster than SD card transfer speeds (see Raspberry Pi Benchmarks).Easy ROM transfer: When the system is off, you can remove the stick and plug it into any other computer and easily copy-and-paste ROMs into the correct folders.Simply remove the USB stick, re-image the SD card, re-apply these setup instructions, and all that data is retained. Separation of data: In the event that a RetroPie installation becomes corrupted or a new image is required, any ROMs, saves, etc, are not lost.Reliability: USB storage can be less sensitive to corruption than SD cards.Rather than running everything from an SD card, it can be desirable to store and run ROMs from an external USB drive.
