4. Operating Instructions
Game Storage and Playback
The Avolusion HD250U3-WH external hard drive functions differently for Xbox One games and Xbox Series X|S optimized games:
- Xbox One Games: You can store and play Xbox One games directly from the Avolusion USB Gaming HDD. This frees up space on your Xbox Series X|S console's internal storage.
- Xbox Series X|S Games: Xbox Series X|S optimized games must be played directly from the console's internal SSD. The external USB HDD can only be used to store these games as a buffer. To play an Xbox Series X|S game, you will need to copy the game data from your USB hard drive back to your console's internal SSD storage. Copying is significantly quicker than re-downloading the game.
