SanDisk Ultra 256GB SDXC card

This SanDisk Ultra SDXC card delivers 256GB of storage in the standard full-size SD form factor. It carries a Class 10 speed rating and a maximum read speed of 100MB/s over the UHS-I bus. The card is brand new and intended for devices that accept SDXC media.

Suited to everyday photo and video capture

Photographers and videographers recording Full HD footage or shooting JPEG and RAW stills will find the capacity and Class 10 sustained write performance adequate. Users who need guaranteed minimum write speeds for 4K recording or extended burst shooting should consider cards with higher speed class ratings.

Class 10 sustained write performance

The Class 10 rating guarantees a minimum sequential write speed of 10MB/s, which is the single specification that determines whether the card can keep up with your camera's data rate. Verify that your device supports SDXC capacity and UHS-I speeds before purchase.

Questions about this item

How can I confirm the card is delivering the rated 100MB/s read speed after formatting?

Use a PC card reader and run a benchmark tool such as CrystalDiskMark; sustained sequential reads at or above the rated figure indicate the card is performing to spec.

What accessories are included and what must I supply separately?

The package contains the 256GB SDXC card only; a compatible SD card reader or device slot is required for data transfer.

Which capacity from the Ultra line should I choose for extended 4K video recording?

The 256GB version provides the largest single-card capacity in this series, reducing the need to swap cards during long shoots.
