Ready for compact cameras

This 128GB SanDisk Ultra SDXC card is built for compact to mid-range point-and-shoot cameras that use full-size SD media. It carries UHS-I, U1 and Class 10 ratings with read speeds up to 120MB/s. The capacity suits day-to-day photo and Full HD 1080p video capture.

Not for high-bitrate workflows

Photographers who need sustained write performance for 4K video or higher video speed classes should look elsewhere. The card targets standard Full HD recording and general backup use rather than demanding continuous capture.

UHS-I U1 Class 10 rating

The single specification that decides fit is the UHS-I U1 Class 10 speed rating, which guarantees minimum write performance for Full HD video. Check your device manual to confirm this class meets its requirements.

Questions about this item

Will the 120MB/s read speed of this SDXC card work with my older camera that only supports standard SDHC cards?

This is an SDXC card, so it requires a device with an SDXC-compatible slot; an older SDHC-only camera cannot use it regardless of the UHS-I interface.

How can I confirm the card delivers the rated 120MB/s read speed after I put it in my computer?

Use a UHS-I compatible card reader and run a benchmark tool such as CrystalDiskMark; sustained sequential reads near 120MB/s show the card and reader are performing to spec.

Does the SanDisk Ultra 128GB card come with a card reader or adapter in the package?

The box contains only the SDXC memory card; a UHS-I card reader or microSD adapter must be purchased separately if your system lacks a built-in SD slot.
