Xbox Series X|S storage expansion cards can be used on PC with an inexpensive CFexpress adapter — Speeds top out at 1,560 MB/s in Redditor's testing

You can now use Xbox Series X|S Storage Expansion Cards on a PC with a PCIe to CFexpress adapter, achieving speeds up to 1,560 MB/s according to a Redditor's testing. While the PS5 has a dedicated M.2 slot for external storage, Xbox Series X|S relies on proprietary Storage Expansion Cards. These cards can be repurposed for PC use with inexpensive CFexpress adapters, offering an alternative storage solution. However, the cards need to be formatted for Windows use, and their speeds may be slower than standard PCIe 3.0 drives. Seagate and Western Digital offer various storage capacities for these Expansion Cards, with Western Digital models often being more affordable.
