SanDisk Extreme 64GB SDXC card

This 64GB SDXC card targets photographers and videographers who need reliable performance for continuous burst shooting and 4K UHD recording. It carries UHS Speed Class 3 and Video Speed Class 30 ratings to meet the demands of high-resolution capture. The UHS-I interface works with SDHC and SDXC compatible devices.

Sustained write performance for long sessions

The card delivers write speeds up to 40 MB/s with a peak capability of 60 MB/s for burst sequences. U3 and V30 ratings guarantee minimum sustained throughput for uninterrupted 4K UHD video recording. Read speeds up to 90 MB/s accelerate file offloads after extended shoots.

Simple installation with common pitfalls

Insert the card into any SDHC or SDXC slot until it clicks; no drivers or tools are required. Verify the host device supports UHS-I to reach rated speeds. Formatting in-camera before first use avoids file-system errors, and write-protection tabs must be disengaged for recording.

Questions about this item

Does the 90 MB/s read speed generate noticeable heat during all-day 4K UHD recording?

SD cards have no moving parts and draw very little power, so the 64 GB Extreme stays cool even during continuous 4K UHD capture at U3 V30 sustained write rates.

What host device slot is required for the UHS-I U3 V30 64 GB card to work?

Any camera, camcorder or card reader with an SDHC or SDXC slot that supports UHS-I will recognise the card and enable its 90 MB/s read and 40 MB/s write performance.

Will this 64 GB Extreme card work reliably in an older DSLR that only supports Class 10 speeds?

Yes — the card is backward compatible with Class 10 hosts; it will simply operate at the host’s maximum speed while retaining its 64 GB capacity and U3 V30 ratings.
