The SanDisk Extreme UHS-I SDXC memory card provides 256 GB of storage for full HD, 3D and 4K video recording as well as raw photography. It operates on the UHS-I bus with a V30 speed class rating. A built-in write-protect switch helps prevent accidental data loss.

Photographers and videographers on UHS-I gear

Questions about this item

Will the 150 MB/s read speed work with my older UHS-I card reader?

The card uses the UHS-I bus, so it will function with any UHS-I reader, though the 150 MB/s read and 60 MB/s write peaks depend on the reader supporting those rates.

How can I verify the V30 rating is sustaining 30 MB/s during 4K recording?

Check your camera’s on-screen write-speed indicator or run a sustained write test on a PC; a steady 30 MB/s or higher confirms the V30 class is being met.

Does the package include a USB adapter or only the 256 GB SDXC card with its write-protect switch?

Only the SDXC card itself is supplied; a USB card reader or adapter must be purchased separately.
