Professional cinema storage

The SanDisk Extreme PRO CFast 2.0 256GB card targets broadcast, cinema and photography professionals who need reliable high-capacity media for 4096x2160p recording. It delivers the sustained throughput that professional camera equipment demands during long shooting sessions.

Sustained write speed 450MB/s

The decisive specification is the maximum write speed of 450MB/s, which determines whether the card can keep pace with cinema-quality 4K capture without dropping frames. Cards with lower sustained write rates will bottleneck high-bitrate recording workflows.

Consistent throughput under load

Rated read speeds reach 525MB/s for rapid offload of large footage volumes between takes. The card maintains its performance envelope during continuous burst photography and extended video runs, avoiding the thermal throttling that affects lesser media under sustained write pressure.
