Licensed Nintendo Switch storage

The SanDisk 256GB microSDXC card is an officially licensed accessory designed specifically for the Nintendo Switch console. It provides a substantial 256GB of capacity to store a large library of digital games, save files, and downloadable content without constant space management.

UHS-I Class 10 performance

The card uses a UHS-I interface rated at Class 10, delivering read speeds up to 100MB/s and write speeds up to 90MB/s. This specification reduces game loading times and supports smooth gameplay transitions directly from the card.

Speed ceiling for demanding titles

The UHS-I bus caps maximum throughput, so the card cannot saturate faster interfaces or match the sustained write performance required by higher-bitrate recording formats. Buyers needing faster random I/O for non-Switch devices should note this inherent interface limit.
