The Lexar Professional Workflow CFexpress 4.0 Type A Card Reader is designed to pair with the Professional Workflow Docking Station and Workflow Go via its 40 Gb/s USB-C interface. It also includes a USB-C to USB-C cable for standalone use. This reader features a CFexpress 4.0 Type A card slot, full compatibility with Windows and Mac, and backward compatibility with CFexpress 2.0 Type A. Its aluminum finish offers scratch resistance, and it works with USB 2.0 and later systems, though transfer speeds will be slower on those older connections.
