Lexar Professional CFexpress Type B / SD USB 3.2 Gen 2 Reader RW520

The RW520 reads CFexpress Type B at up to 1050 MB/s and SD at up to 312 MB/s, which matches the two-slot layout of the mirrorless bodies it is built for: the CFexpress card holds the raw takes, the SD card holds the proxy or the backup, and both come off in one connection. USB 3.2 Gen 2 over a Type-C connector is what carries that speed.

It ships with a 2-in-1 cable, USB Type-C to Type-A and Type-C to Type-C, so it connects to a current laptop or an older tower without a dongle. Mac OS 10.8 and Windows back to XP are supported on any USB 2.0 or newer port; note that the CFexpress slot accepts Type B cards only, marked with the boxed USB logo on the label.
