SanDisk 256GB microSDXC UHS-I Memory Card (SDSQXAO-256G-GNCZN)

Nintendo Switch licensed storage

This officially licensed microSDXC card adds 256GB of capacity to the Nintendo Switch game system. It is built for players who want to keep multiple titles, screenshots and videos on a single card without swapping media. The UHS-I interface delivers read speeds up to 100MB/s and write speeds up to 90MB/s for quicker game loading. It suits anyone expanding the internal storage of a Switch console.

Passive operation with no thermal load

The card has no moving parts and draws power directly from the console slot, so it produces no audible noise and adds negligible heat during normal use. Power consumption scales with the UHS-I bus activity and stays within the limits of the host device. There are no fans, heatsinks or external power requirements to consider. It runs silently in handheld or docked mode.

Consistent throughput during extended play

Sustained read and write rates remain at the rated UHS-I limits during long gaming sessions or large file transfers. The flash memory maintains performance without thermal throttling because the card generates minimal heat. Write speeds up to 90MB/s support continuous capture of gameplay footage. The card is tested for reliability under the access patterns typical of Switch titles.
