64 GB SDXC card for pros

The SanDisk Extreme Pro SDXC card delivers 64 GB of storage for professionals and serious creators who shoot 4K UHD video and high-resolution stills. It carries UHS-I, Class 10, U3 and V30 ratings to sustain continuous recording without dropped frames. The card is built for demanding workflows where reliability and speed matter most. It is not suited for buyers who need more storage than 64 GB.

Capacity and headroom at 64 GB

The 64 GB capacity holds extended 4K UHD sessions and large bursts of high-res photos before offloading. Sequential write speeds reach up to 90 MB/s and read speeds up to 200 MB/s on this model, keeping buffer clears fast during continuous shooting. Higher capacities in the same series offer up to 170 MB/s write and 250 MB/s read, so this card runs out of throughput first for the most intensive workflows. Users needing sustained write performance beyond 90 MB/s should look at larger capacities.

Thermals, noise and power draw

As a solid-state memory card with no moving parts, it produces no audible noise and generates negligible heat during normal read and write operations. Power draw is minimal, sourced directly from the host device’s SD slot without requiring external power. The card is designed, built and tested for durability across temperature extremes, shock, vibration and X-ray exposure. There are no fans, radiators or thermal throttling concerns to manage.

Questions about this item

Will the UHS-I interface work with my older camera that only supports standard SDHC cards?

The card uses the UHS-I interface, which is backward compatible with standard SDHC slots, though it will operate at the host device's maximum supported speed rather than the rated 200MB/s read or 90MB/s write speeds.

How can I verify the card delivers the rated V30 video speed class after formatting it in my camera?

Record a 4K UHD clip at a sustained bit-rate above 30MB/s; if the camera writes without dropped frames or buffer warnings, the V30 rating is being met.

Does the package include a card reader or do I need to buy one separately to reach the 250MB/s read speed on my laptop?

The box contains only the 64GB SDXC card; a UHS-I compatible reader capable of 250MB/s transfers must be purchased separately.
