USB4 CFexpress Type B Card Reader

The Sabrent CR-U4XB is a USB4 card reader built for photographers and videographers who use CFexpress Type B memory cards. It connects via USB-C and delivers up to 40Gbps bandwidth for fast offloads in the field or studio. The aluminium alloy body aids heat dissipation during long transfers, while a detachable cable and silicone sleeve add durability and mounting flexibility.

40Gbps USB4 Interface

The single specification that determines suitability is the USB4 interface rated at 40Gbps, enabling real-world transfer speeds up to 3500MB/s. This reader is backward compatible, bus-powered, and supports OTG for direct connection to cameras, laptops, or cages without external power. It accepts one CFexpress Type B card at a time and requires a host with USB-C.

CFexpress Type B Capacity and Headroom

The reader handles CFexpress Type B cards of any capacity, moving large RAW photo bursts and high-bitrate video files at the full speed the card and host allow. It runs out of headroom when the host port is limited to slower USB standards, which reduces throughput below the 3500MB/s ceiling. It does not support CFexpress Type A, SD, or other card formats.

Questions about this item

What does the 3500 MB/s figure mean when the reader is connected to my computer?

That number is the peak real-world transfer rate the USB4 link can sustain with a fast CFexpress Type B card; actual speed depends on the card and the host port.

Which interface standard does the reader use and what throughput does it cap at?

It uses a USB4 connection rated at 40 Gbps, which limits maximum throughput to that bandwidth.

What does the reader need physically to mount on a camera cage?

Its compact aluminium body and optional silicone sleeve let you attach it directly to cages or cameras for field recording.
