The Atlas CFexpress Type B Card Reader from OWC (Other World Computing) delivers ultra-fast performance to streamline your workflow. Featuring a single CFexpress 4.0 Type B slot, it leverages the power of the 40 Gb/s USB4 interface to achieve blazing transfer speeds up to 5000 MB/s. Compatible with Windows, Mac, Chrome, iOS, iPadOS, and Android, it works seamlessly with USB-C, Thunderbolt 3, and Thunderbolt 4 ports, and is fully bus powered for maximum portability. An integrated LED indicator shows operational status, while non-skid rubber feet provide added stability. The reader comes with a 20" USB4 cable and a CFexpress Type A to Type B adapter—intended exclusively for use with this reader and not with cameras.
Please note that to obtain maximum performance, Apple systems with M2, M1 Pro, and M1 Max processors should update to macOS 13.3 or later. Apple systems with an M1 chip will experience lower data transfer speeds due to M1 limitations. Thunderbolt 3 requires macOS 11.1 or later.
