Professional CFexpress Type B reader

The SanDisk Extreme PRO CFexpress Type B Card Reader is built for photographers and videographers who need to offload high-resolution images and raw 4K footage quickly. It accepts CFexpress Type B cards and connects via USB Type-C for use with modern computers and iPad Pro devices. Plug-and-play operation on Windows and macOS keeps the workflow simple from location to post-production.

1250 MB/s maximum read speed

The single specification that determines suitability is the rated read speed of up to 1250 MB/s over a USB 3.1 Gen 2 connection. This throughput is designed to match the performance ceiling of CFexpress Type B media so that large files move without bottleneck. If your production demands sustained transfers at or near this rate, the reader is specified to deliver it.

Passive thermal design and bus power

The unit has no fan or active cooling; heat dissipates through its metal enclosure during normal operation. It draws power directly from the host USB-C port, so no external adapter is required and there is no audible noise. A 0.5 metre USB-C cable is included for flexible desk placement.
