256 GB SDXC card for point-and-shoot cameras

This SanDisk Ultra SDXC card delivers 256 GB of storage in the full-size SD form factor. It is aimed at photographers using compact to mid-range point-and-shoot cameras who need reliable capacity for stills and Full HD video. The UHS-I interface provides read speeds up to 150 MB/s for faster offloading. The card carries U1 and Class 10 ratings for sustained write performance.

Check device slot and speed requirements

Before ordering, verify that your camera or recorder accepts SDXC cards and supports the UHS-I bus. Confirm that the device’s maximum video mode is 1080p, because the U1 and Class 10 ratings guarantee the minimum write speed needed for Full HD recording. Ensure your card reader or computer slot can handle SDXC capacity and UHS-I speeds to achieve the quoted 150 MB/s read rate.

Fits standard SD slots and frees internal buffer

The card slots directly into any full-size SDXC-compatible device without adapters. Its 150 MB/s read speed clears the camera’s buffer quickly between bursts, letting you shoot longer sequences. The 256 GB capacity reduces the need to swap media during a day of shooting. A compatible UHS-I reader (sold separately) enables fast backup to a computer.

Questions about this item

Does the box include a card reader or do I need to buy one separately?

Only the 256GB Ultra SDXC card is included; a compatible SanDisk SD UHS-I card reader is sold separately.

The listing shows UHS-I, U1 and Class 10 — which rating should I match to my camera?

All three ratings describe the same card; choose it if your device supports UHS-I or requires Class 10 for Full HD recording.

The 150MB/s read speed is quoted — what does that mean when I copy files to my laptop?

That is the maximum transfer rate under ideal conditions; real-world copies will be slower depending on your reader and USB port.
