Professional burst and 4K capture

The SanDisk Extreme Pro 64GB SDXC UHS-II card delivers read speeds up to 300 MB/s and write speeds up to 260 MB/s. It meets UHS Speed Class 3 (U3) for sustained 4K video recording. The 64GB capacity handles extended RAW plus JPEG sequences.

Fits UHS-II slots for maximum throughput

The card requires a UHS-II compatible camera or reader to reach the rated 300 MB/s transfer rate. In UHS-I devices it falls back to lower speeds. It frees post-production workflow by moving large files quickly from the card to the workstation.

Steps up from UHS-I and lower-capacity cards

Photographers limited by slower write speeds or smaller 32GB cards gain headroom for longer bursts and cinema-quality 4K. The jump is worth it when continuous shooting or high-bitrate video regularly fills the buffer or storage.

Questions about this item

How long can the card sustain 260 MB/s write before the buffer fills?

The card is rated for up to 260 MB/s write; sustained duration depends on the camera's buffer and file sizes, which vary by model and shooting mode.

Does the card run hot or draw extra power during all-day 4K recording?

The card operates within standard SDXC power limits; UHS-II cards may run warmer under continuous 260 MB/s write, but no specific thermal or power figures are published.

What camera slot is required to use the UHS-II speeds?

A UHS-II compatible SDXC slot is needed to achieve the 300 MB/s read and 260 MB/s write rates; older UHS-I slots will fall back to lower speeds.
