The SanDisk 256GB CFast 2.0 Extreme Pro Memory Card has the speed, capacity, and performance needed to record uninterrupted DCI 4K video (4096 x 2160). It has a maximum read speed of up to 525MB/s, a maximum write speed of up to 450MB/s, and a minimum write speed of 130MB/s, which is backed up by the Video Performance Guarantee 130 standard (VPG-130) so that its minimum write speed will never drop below 130MB/s. The CFast format is a continuation of the more familiar CF, or Compact Flash, format but they are not interchangeable. CFast currently is compatible with only select professional-grade cameras.
