Capacity and use-case

The SanDisk Ultra SDXC card provides 64GB of storage for compact and mid-range point-and-shoot cameras. It supports Full HD video recording at 1080p thanks to its UHS-I U1 and Class 10 ratings. Photographers shooting RAW or JPEG files will find the capacity sufficient for everyday sessions.

Sustained write performance

The card guarantees a minimum write speed of 10MB/s to maintain consistent Full HD video capture without dropped frames. Read speeds reach up to 140MB/s for fast offloads to a computer. Performance remains steady during extended recording sessions rather than only in short bursts.

Compatibility checks

Verify that your camera or device accepts full-size SDXC cards before purchase. A UHS-I capable card reader is required to achieve the quoted 140MB/s transfer rate. The card is water, shock and x-ray resistant for outdoor use.

Questions about this item

Does the SDSDUNB-064G-GN6IN run hot or draw extra power during long shoots?

SD cards have no moving parts and draw very little power, so the 64 GB Ultra stays cool during extended Full HD recording.

What device or reader do I need to reach the 140 MB/s read speed?

A UHS-I compatible SD card reader or camera slot is required to achieve the 140 MB/s maximum read rate.

Will this card work in my older camera that only supports Class 10?

Yes, the card is rated Class 10 and U1, so it functions in any SDXC slot that accepts Class 10 media.
