SanDisk Express microSD Memory Card

While this card is optimized for the Nintendo Switch 2, it is backward compatible with UHS-I and UHS-II devices. This means you can use it in your current Nintendo Switch, though you will not experience the maximum PCIe NVMe speeds until you upgrade to the newer console.

The PCIe 3.1 NVMe interface allows for significantly faster data transfer rates than traditional microSD cards. This results in much shorter game load times and smoother performance when running demanding applications directly from the card.

Yes, this card is well-suited for high-resolution 4K video capture. It carries a V30 Video Speed Class rating, which ensures the sustained write speeds necessary to handle the data demands of 4K recording without dropping frames.

The A1 rating indicates that the card is optimized to handle random read and write operations efficiently. This is particularly important for gaming consoles and smartphones, as it allows apps and games stored on the card to launch and run with responsiveness similar to internal storage.

No, the 880 MB/s sequential read speed is only achievable when using a compatible reader or device that supports the PCIe 3.1 NVMe interface. On older devices that only support standard UHS-I or UHS-II protocols, the card will operate at the maximum speed allowed by that device's hardware.
