CFexpress Type B single-slot reader

The Lexar LRW550U-RNBNU is a 1-in-1 card reader built exclusively for CFexpress Type B media. It connects through USB-C and USB-A ports using the supplied dual-head cable, so it works with modern laptops and desktops without extra adapters. The matte-black housing measures 2.77 x 0.75 x 0.51 inches and slips into a pocket or gear bag. Photographers and videographers who shoot on CFexpress Type B cards get a dedicated, driver-free offload tool.

Up to 1700 MB/s transfer over USB 3.2 Gen 2x2

The reader tops out at 1700 megabytes per second when paired with a compatible host port and card, letting you move RAW 8K video and high-resolution stills in a fraction of the time older USB readers need. That single number decides whether the device keeps pace with your shooting volume. If your computer only offers slower USB generations, the reader will still work but will not reach the quoted ceiling.

For CFexpress Type B shooters needing maximum

Creators who rely on CFexpress Type B cards and have a USB 3.2 Gen 2x2 port will see the full workflow benefit. Users with only SD, CompactFlash, MMC or xD media cannot use this reader at all, as it lacks slots for those formats. Buyers whose systems top out at USB 3.2 Gen 2 or earlier will not hit the 1700 MB/s rate and may prefer a less specialised reader.
