The OWC CFexpress Type B and Type A 4.0 memory card reader – Silver offers a high-speed workflow with fast transfer speeds. Equipped with a CFexpress Type B 4.0 slot, this reader takes advantage of the 40 Gb/s USB4 bus to offer transfer speeds of up to 5000 MB/s. Compatible with Windows, Mac, Chrome, iOS, iPadOS and Android, this card reader can be used with USB-C, Thunderbolt 3 and Thunderbolt 4 ports and works with bus power. An integrated LED indicator allows users to confirm the status of use, and non-slip rubber feet help keep it in place. A 20-inch USB4 cable is included. For maximum performance, Apple systems with M2, M1 Pro and M1 Max processors must be upgraded to macOS 13.3 or later. Apple systems with M1 chips will have lower data transfer rates due to M1 limitations.
