128 GB microSDXC Ultra card

The SanDisk Ultra SDSQUNS-128G is a 128 GB microSDXC card rated Class 10 UHS-I. It targets photographers, drone pilots and mobile users who need reliable capacity for Full HD video and high-resolution photos. The card delivers sequential read speeds up to 80 MB/s for quick file transfers.

Micro form factor and speed class

The microSDXC form factor fits smartphones, action cameras, tablets and Nintendo Switch consoles with a microSD slot. Class 10 UHS-I rating guarantees a minimum sustained write speed of 10 MB/s for smooth video recording. Read performance up to 80 MB/s reduces offload time when moving large batches to a computer.

Check host device compatibility

Verify that your device supports the microSDXC standard and UHS-I speeds before ordering. Older hosts limited to microSDHC will not recognise the 128 GB capacity. Maximum throughput depends on the card reader or host controller used.
