Professional CFast 2.0 storage

The SanDisk Extreme Pro 256GB CFast 2.0 card delivers read speeds up to 525MB/s and write speeds up to 450MB/s. It targets professional videographers working in cinema, broadcast and media production who need reliable high-throughput capture.

Thermal and power profile

The card operates without active cooling and draws power directly from the host device. In normal recording workflows it runs silently and maintains stable temperatures inside compatible cameras or recorders.

Sustained write behaviour

The 450MB/s write rating supports continuous high-bitrate recording without dropped frames. The 256GB capacity holds extended takes, though users needing longer multi-camera sessions will require additional cards.

Questions about this item

How do I install the SanDisk Extreme Pro 256GB CFast 2.0 card and what step is often missed?

Insert the card into a CFast 2.0 slot with the label facing the correct direction until it clicks; the step people miss is formatting the card in the camera before the first shoot to avoid file-system errors.

What maintenance or replacement will this 256GB CFast card need over time?

No scheduled maintenance is required; replace the card if sustained write speeds drop below 450MB/s, if read errors appear, or after heavy use in cinema workflows that exceed its endurance rating.

What limit appears first when recording continuously at high bitrates on this card?

The sustained write ceiling of 450MB/s is the first bottleneck; if your camera's codec demands more, frames will drop before the 256GB capacity fills.
