Professional SDXC card for cinema workflows

This SanDisk Extreme PRO SDXC card delivers UHS-II performance with V90 sustained write speeds for professional cameras. It supports cinema-quality 8K video recording and high-resolution continuous shooting. The 256GB capacity stores up to 286 minutes of standard 8K video at 30 fps. It is built for photographers and videographers who need reliable capture without dropped frames.

IP68 rated for extreme conditions

The card is IP68 rated for water and dust resistance and withstands drops from up to 6 meters (19.6 feet). This durability protects footage in harsh outdoor environments and demanding production sets. A compatible UHS-II reader enables offload speeds up to 300MB/s for accelerated post-production workflows. The robust construction ensures the card remains a dependable partner on location.

Upgrade from slower V30 or V60 cards

Moving to this V90 card eliminates buffer bottlenecks during high-bitrate 8K or 4K 60 fps recording. The jump is worth it when your current card cannot sustain 90MB/s minimum write speeds, causing interrupted clips. It is not suited for buyers who need more than 256GB of storage per card. Older cameras without UHS-II support will not benefit from the rated speeds.
