256GB microSDXC for Nintendo Switch

The SanDisk 256GB microSDXC card is officially licensed for Nintendo Switch and expands the console's internal storage by 256GB. It targets Switch owners who want more space for digital games, screenshots and save data without deleting older titles.

Upgrading from smaller Switch cards

The card replaces lower-capacity microSD cards such as 64GB or 128GB models when the game library outgrows them. The jump is worth it when you regularly manage space or wait for downloads because the internal memory and a smaller card are full.

Sustained read and write speeds

Sequential read speeds reach up to 100MB/s and write speeds up to 90MB/s based on internal testing, so loading large games and saving progress remain steady during long sessions. Performance may be lower depending on the host device interface and usage conditions.

Questions about this item

Does the 256GB microSDXC card fit the Nintendo Switch slot?

Yes, the microSDXC form factor matches the Nintendo Switch card slot exactly, so the 256GB card inserts directly without adapters.

What is the correct way to insert the card so the Switch recognises it?

Power off the console, open the kickstand, insert the card label-side up until it clicks, then power on; the step users miss is inserting it before the system is fully off.

How long is the card covered if it fails?

The card carries a lifetime limited warranty, which is honoured as a 30-year warranty in Germany, Canada and other regions that do not recognise lifetime terms.
