CFexpress Type B USB 3.2 Gen 2x2 Reader - Fast Transfers for Pro

In this review of the Lexar Professional CFexpress Type B USB 3.2 Reader, the bottom line is simple: this compact reader is aimed at photographers and videographers who need consistently fast offloads of high-resolution files. It delivers the single biggest advantage of dramatically reduced wait times thanks to sustained read speeds up to 1700MB/s over USB 3.2 Gen 2x2, making it a practical tool for anyone working with RAW 8K video and large image libraries. The reviewer found it straightforward to use, portable for location work, and well matched to both Mac and PC setups.

Key Features

• Designed for CFexpress Type B: Ensures full compatibility with CFexpress Type B cards so cards work without adapters or reduced performance.
• Up to 1700MB/s read: Offers blistering read speeds that cut transfer time for RAW 8K video and large photo shoots.
• USB 3.2 Gen 2x2 technology: Leverages the faster host interface to dramatically accelerate workflow when a compatible port is available.
• Portable and compact: Small, lightweight construction makes it easy to toss in a camera bag for location shoots and on-the-go editing.
• Included 2-in-1 cable: Ships with a 30cm cable offering USB-A to USB-C and USB-C to USB-C ends for flexible connectivity across older and newer computers.

Who It's For

This reader is best for professional photographers, videographers, and content creators who regularly capture large RAW files or 8K video and need fast, reliable offloads to stay productive. Those who edit on laptops or desktops with USB 3.2 Gen 2x2 ports will see the greatest real-world benefit from the higher transfer rates.

Casual users who only shoot JPG or small video files, or people without access to a Gen 2x2 host port, should weigh whether their current USB ports will limit the reader's peak speed; the device still functions on USB-A and USB-C ports but at lower transfer rates.

Pros & Cons

Pros

• Very fast read performance that noticeably shortens file transfer times for heavy workloads.
• Compact, solid build quality that fits easily in a travel kit.
• Flexible connectivity with the included 2-in-1 cable for USB-A and USB-C hosts.

Cons

• Requires a USB 3.2 Gen 2x2 port to reach the full 1700MB/s speed, which not all computers have.
