128GB microSDXC for Nintendo Switch

This officially-licensed SanDisk card adds 128GB of storage to a Nintendo Switch console. It uses the microSDXC form factor and carries a UHS Speed Class 3 rating. Read speeds reach up to 100MB/s and write speeds up to 90MB/s. The card is sold new and ready for immediate use.

Suits Switch owners who need more game space

Players who want to keep multiple large titles installed will benefit from the extra capacity and the U3 speed class. The card is designed specifically for the Switch ecosystem. Users who require higher capacities for extensive libraries or who need faster sustained write speeds for 4K video capture should consider other options.

UHS Speed Class 3 (U3) rating

The U3 marking guarantees a minimum sequential write performance level that supports Full HD video recording and smooth game loading on the Switch. This single specification determines whether the card meets the console's requirements for playable performance. Verify that your device accepts microSDXC cards before purchase.
