Direct Xbox Series X/S Compatibility

Engineered exclusively for Microsoft's Xbox Series X and Series S hardware, this expansion card plugs directly into the dedicated expansion port on the rear of the console. By matching the internal performance architecture of Xbox hardware, it allows players to store and play modern games directly from the external card without sacrificing speed or graphical features.

Seamless 1TB Capacity Expansion

With 1TB of total storage space, this expansion card effectively doubles or triples the usable storage footprint of your Xbox console. It comfortably holds dozens of large modern games, sparing buyers the inconvenience of constantly uninstalling and re-downloading titles to free up space.
