Capacity and card type

This SanDisk Extreme Pro card is a 64GB Secure Digital Extended Capacity (SDXC) memory card in the full-size SD form factor. It carries UHS Speed Class 3 (U3) and Video Speed Class 30 (V30) ratings alongside a Class 10 designation. The card is built for cameras and other devices that accept SDXC media. Photographers and videographers who need reliable, high-speed storage for 4K UHD footage will find it suited to that workload.

Speed-class upgrade path

The U3 and V30 ratings guarantee a minimum sustained write speed of 30MB/s, which is the threshold for uninterrupted 4K UHD video recording. Cards limited to Class 10 or U1 can drop below that floor during long takes, causing dropped frames. If your current media only carries those lower ratings, this card removes that bottleneck. The jump is worth it whenever the camera writes at or near the V30 sustained level.

Durability profile and buyer fit

The card is tested to be temperature-proof, waterproof, shockproof and x-ray-proof, making it a fit for outdoor, travel and action shooting where gear faces rough handling or extreme environments. Users who only shoot stills at modest burst rates or record lower-resolution video may not need the V30 guarantee or the ruggedised build. Buyers who want more storage should consider the 128GB or 256GB versions of the same series.

Questions about this item

Will this full-size SDXC card fit in my camera's standard SD slot?

Yes, the card is a full-size SDXC model that fits any standard SD card slot supporting SDXC capacity.

Do I need to format the card in-camera before first use to ensure 4K UHD recording works?

Format the card in your camera before shooting; this sets the correct file system so the U3 and V30 ratings can sustain 4K UHD video without interruption.

How do I know when the card is nearing the end of its write-cycle life?

The card has no built-in wear indicator; monitor for slower write speeds or write errors and replace it when performance drops below your workflow needs.
