Wise CFexpress 4.0 Type A Mk-II 256GB Memory Card – Product Overview
The Wise CFexpress 4.0 Type A Mk-II 256GB is a professional recording card designed for compatible Sony Alpha mirrorless cameras and FX cinema cameras. Its PCIe Gen 4 x1 / NVMe 1.4 interface supports high-data-rate video and responsive burst-photo workflows. The Type A form factor is physically distinct from CFexpress Type B: confirm camera slot compatibility before ordering.
Recording Performance
With up to 1,865 MB/s read and 1,750 MB/s write, this card supports efficient ingest, camera buffer clearing and high-quality recording. Importantly, its VPG400 certification represents a minimum guaranteed sustained write rate of 400 MB/s under the applicable video-performance standard; it is not the same as the higher peak write specification.
Capacity and Compatibility
The 256GB capacity offers practical room for high-bitrate video and RAW photo sequences. Pair the card with an appropriate CFexpress Type A USB4 reader and a sufficiently fast host SSD to make the most of offload speeds. Camera firmware, recording mode, host hardware and file characteristics all affect achievable performance.

- Certified VPG400 for supported professional video modes requiring sustained 400 MB/s recording
