Samsung P9 Express microSD Express Card 256GB

This microSD Express card delivers sequential read speeds up to 800 MB/s for Nintendo Switch 2 and compatible devices. It provides 256GB of storage capacity for games and downloadable content in a compact form factor.

Upgrade from standard UHS-I microSD cards

The card performs up to four times faster than Samsung standard UHS-I microSD cards when used in microSD Express slots. The performance jump is worth it for Switch 2 owners who want reduced loading times and quick access to large game libraries.

Limited by host device interface speed

In devices that only support UHS-I, the card operates at UHS-I speeds instead of its maximum 800 MB/s capability. Buyers with older tablets, drones or cameras will not see the Express speed benefit until they upgrade to a microSD Express compatible host.
