The Lexar Professional Workflow CFexpress 4.0 Type B Card Reader is designed to pair with the Professional Workflow Docking Station and Workflow Go through its 40 Gb/s USB-C interface. It also includes a USB-C to USB-C cable, allowing for standalone use. This card reader features a CFexpress 4.0 Type B card slot, and offers compatibility with both Windows and Mac systems. It is backward compatible with CFexpress 2.0 Type B cards and has a scratch-resistant aluminum finish. For systems not supporting the 40 Gb/s USB4 standard, the reader is also compatible with USB 2.0 and later, although transfer speeds will be slower.
