For those working in high-performance industries such as broadcasting, cinema, and photography, the 256GB Extreme PRO CFast 2.0 Memory Card from SanDisk combines the speed, capacity, and performance needed to record uninterrupted DCI 4K video, which has a resolution of 4096 x 2160 and a 17:9 aspect ratio. It features a SATA III 6 Gb/s bus, a maximum read speed of up to 525 MB/s (3500x), a maximum write speed of up to 450 MB/s (2933x), and a minimum write speed of 130 MB/s.
