Professional photography workflow

The SanDisk Extreme Pro 256GB UHS-I SDXC card is built for photographers and videographers who need reliable performance when capturing high-resolution stills and 4K UHD video. Its U3 and V30 ratings guarantee the sustained write speeds required for uninterrupted recording. This capacity suits extended shoots without frequent card swaps. Casual users needing only basic storage for documents or standard-definition footage will not benefit from the speed premium.

Rugged full-size SD construction

The full-size SD form factor fits directly into professional camera bodies, laptop slots and external readers without adapters. Rated to withstand weather, water and shocks, the card protects data in unpredictable outdoor environments. No moving parts mean silent operation and resistance to vibration during handheld or vehicle-mounted shooting. Builds requiring microSD or CFexpress formats cannot use this card.

Accelerated post-production transfer

Read speeds up to 170MB/s move large 4K files and burst sequences to editing workstations quickly, reducing downtime between shooting and delivery. The 90MB/s write speed supports continuous burst photography without buffer delays. No bundled software or recovery tools are included with this card. Users needing proprietary file-rescue utilities must source them separately.
