CFexpress 4.0 Type B reader

The Lexar Professional Workflow CFexpress 4.0 Type B Card Reader accepts CFexpress 4.0 and 2.0 Type B cards. It connects through a 40 Gb/s USB-C interface and includes a USB-C to USB-C cable for standalone operation. A scratch-resistant aluminum finish protects the unit. ||

Photographers and video editors

This reader suits photographers and video editors who need fast offload from CFexpress 4.0 Type B media on Windows or Mac. It pairs with the Lexar Professional Workflow Docking Station and Workflow Go for multi-card workflows. Buyers using only SD, CFast or CFexpress Type A cards cannot use this slot. ||

40 Gb/s USB-C interface

The single specification that decides fit is the 40 Gb/s USB-C connection. Your host must support this bandwidth to reach CFexpress 4.0 speeds; otherwise the reader falls back to USB 2.0 and later with reduced transfer rates. Verify the port capability before purchase.

Questions about this item

Does the CFexpress 4.0 Type B reader run hot or draw much power during long ingest sessions?

The reader has no fan and draws power only from the USB-C bus, so it stays cool and silent even during continuous transfers.

What host port and cable are needed to reach the advertised 40 Gb/s speed?

A USB4 40 Gb/s port on the computer plus the included USB-C to USB-C cable are required for full throughput.

Will my existing CFexpress 2.0 Type B cards work in this 4.0 reader without reformatting?

Yes, the slot is backward compatible with CFexpress 2.0 Type B cards and reads them natively on both Windows and Mac.
