Nintendo Switch licensed storage

This officially-licensed microSDXC card adds 128GB of capacity to the Nintendo Switch game system. It is built for players who want a single card to hold multiple games, screenshots and videos without swapping media.

UHS-I speeds up to 100MB/s read

Sequential read reaches up to 100MB/s and write up to 90MB/s under the UHS-I U3 rating. The solid-state design has no moving parts, so it runs silently and draws minimal power during gameplay or data transfers.

Compact microSDXC form factor

The card measures 0.4 inches wide and 0.6 inches long with a thickness of 39.4 mil, fitting the Switch slot exactly. Its small footprint makes it easy to leave installed permanently or to carry as a spare in a wallet-sized case.

Questions about this item

How do I insert the microSDXC card into the Nintendo Switch without damaging the contacts?

Power off the console, open the kickstand to reveal the slot, and slide the card in label-side up until it clicks; forcing it upside-down bends the 39.4 mil thick contacts.

Will this 128GB card need reformatting or replacement after a certain amount of game data writes?

The card handles normal game saves, screenshots and video captures without user maintenance; only a filesystem error or physical damage would require reformatting or a new card.

At what point does sustained write speed drop below the rated 90MB/s during long gameplay recording sessions?

Continuous 4K capture can push the controller past its thermal limit, causing write throughput to throttle below the 90MB/s peak after several minutes of heavy use.
