A new storage expansion card for Xbox Series X and S was spotted over the weekend at Best Buy, but has since been removed from the store. This option from Western Digital's WD_Black brand would be the first official competitor to the Seagate Expansion Card, which has been available since the earliest days of the console.
The Seagate Expansion Card is by far and away the best Xbox Series X hard drive because it's the closest thing the platform has to an additional internal SSD. The card slots into a small port in the back of either console, resembling the design of a PS2 memory card, and offers more storage for new-gen and last-gen games.
