Nintendo Switch Storage

The officially licensed SanDisk microSDXC card adds 128GB of extra space to the Nintendo Switch console. It uses the UHS-I U3 speed class to deliver read speeds up to 100MB/s and write speeds up to 90MB/s for quick game loading.

Console Integration

The card slots directly into the Switch’s microSD port without adapters or tools. It frees up the limited internal memory so multiple titles and downloadable content can stay installed and ready to play.

Licensed Reliability

Nintendo licensing means the card is tested for compatibility with the console’s file system and firmware updates. The single-card design keeps an entire library in one place, reducing the need to swap media during sessions.
