Quick answer

The Xbox Series X and Series S use a proprietary plug-in expansion card (the Seagate and WD_BLACK C50 cards) rather than the PS5's open M.2 standard. An external USB drive can store Series X|S games and play older backward-compatible titles, but current-gen games run only from the internal SSD or an official card.

Xbox storage vs PS5 storage

Unlike the PS5, you cannot fit a standard M.2 drive to an Xbox Series X|S for current-gen games. The expansion is a sealed proprietary card that matches the internal SSD speed, so you buy the official Seagate or WD versions.

This makes the Xbox upgrade simpler but less flexible and usually pricier per terabyte than a PS5 M.2 drive.

External drives for older games

An external USB drive still has a role on Xbox: it stores Series X|S games and plays backward-compatible Xbox One, 360 and original Xbox titles directly. Only current-gen games are restricted to the internal SSD or an expansion card.

Frequently asked questions

What storage does the Xbox Series X|S use?

A proprietary plug-in expansion card (Seagate or WD_BLACK C50) that matches the internal SSD speed. Unlike the PS5, you cannot fit a standard M.2 drive for current-gen games.

Can I use an external drive on Xbox Series X|S?

Yes, to store Series X|S games and to play older backward-compatible titles. Current-gen games must run from the internal SSD or an official expansion card.

Is the Xbox expansion card the same as a PS5 SSD?

No. The PS5 uses an open M.2 NVMe standard, so any compatible drive works. The Xbox uses a sealed proprietary card, so you buy the official Seagate or WD versions.

Why are Xbox expansion cards more expensive than PS5 SSDs?

Because the format is proprietary, there is far less competition than the open M.2 market the PS5 uses, so Xbox cards usually cost more per terabyte. The trade-off is a simpler plug-in upgrade with no heatsink or installation to worry about.
