32GB SDXC UHS-I card

The SanDisk Ultra SDXC card provides 32GB of storage in the full-size SD form factor. It is rated Class 10 and UHS-I with a maximum read speed of 100MB/s and a write speed of 50MB/s. The card is designed for compact to mid-range point-and-shoot cameras and camcorders. It is built to be waterproof, shockproof, x-ray proof and temperature-proof for durability in varied conditions.

For casual photo and Full HD video

This card suits photographers who shoot stills and 1080p video on entry-level cameras and want a simple, rugged media option. It is not intended for users who need sustained high-bitrate 4K recording or continuous burst shooting that exceeds the 50MB/s write limit. Buyers who require larger capacities for extended sessions should look at higher-capacity alternatives.

Fits standard SD slots and readers

The full-size SD form factor fits directly into any SDXC-compatible camera slot or card reader without an adapter. UHS-I support allows the 100MB/s read speed when paired with a compatible host, speeding up offloads to a computer. The 32GB capacity lets you capture many photos and hours of 1080p footage before swapping cards. No external power or special drivers are required.

Questions about this item

Does my camera need a UHS-I slot and SDXC support to use the 32 GB SanDisk Ultra card?

Yes — the card is UHS-I and SDXC, so the host device must accept both to reach the rated speeds and capacity.

Can I keep using my older Class 10 card reader with this 100 MB/s SanDisk Ultra card?

The card is backward compatible, but the reader will limit transfers to its own maximum speed, well below the card's 100 MB/s read rating.

How can I verify the card delivers the advertised 100 MB/s read and 50 MB/s write after setup?

Run a benchmark tool such as CrystalDiskMark or Blackmagic Disk Speed Test on a UHS-I reader and check that sequential read approaches 100 MB/s and write approaches 50 MB/s.
