This article covers ProGrade デジタルCFexpress Type B カードリーダー USB 4.0 (PG05.6)。.

Overview

The ProGrade Digital PG05.6 is a single-slot CFexpress Type B card reader that leverages USB 4.0 to deliver up to 40Gbps transfer speeds. It's built for professionals who need to move large volumes of high-resolution photos and video footage quickly from their memory cards to their editing workstations. Designed for on-the-go use, the reader includes a magnetic metal plate that can be attached to a laptop, turning the reader into a compact mobile workstation. The PG05.6 is optimized exclusively for CFexpress Type B cards and does not support XQD, ensuring peak read performance for the latest generation of media.

Connectivity & Compatibility

The PG05.6 connects via USB 4.0 Type-C and is backward compatible with USB 3.2 Gen2x2 (20Gbps), USB 3.2 Gen2 (10Gbps), and USB 3.0, though maximum speed will be limited by the host port. It supports only CFexpress Type B cards; XQD cards are not compatible. An included USB 4.0 certified cable ensures full bandwidth. The reader is driverless on both Windows and macOS, so you can plug it in and start transferring immediately.

Product Info

Released in late 2023, the PG05.6 retails for around ￥20,000 in Japan, positioning it as a premium pro-level accessory. It comes with a 2-year warranty covering repair, replacement, or refund. In the box you get the reader, a USB 4.0 cable (approx. 0.8m), two adhesive metal plates, and a quick start guide. The aluminum body dissipates heat effectively, maintaining stable performance during long transfer sessions. Market positioning is clearly high-end: the USB 4.0 interface and 40Gbps throughput target users who demand maximum speed for their professional workflow. Compared to standard USB 3.0 readers, the price is higher, but the time savings for frequent large-file transfers can be significant.

Best Use Cases

Professional photographers and videographers: If you shoot RAW bursts or 4K/8K video on CFexpress Type B cards, the 40Gbps speed means you can offload multi-hundred-gigabyte card dumps in minutes instead of waiting around. You can get back to editing faster. Enthusiast creators: You use a high-end mirrorless camera that records high-bitrate video. The PG05.6 eliminates the bottleneck of slower USB 3.0 readers, making your import workflow as smooth as possible. * Field journalists and event photographers: At a shoot location, you need to quickly transfer files to a laptop for immediate editing or delivery. The magnetic attachment lets you keep the reader attached to the laptop lid, so it stays put and doesn't take up desk space. This reader is not for you if you still use XQD cards, or if your data volume is small enough that USB 3.0 speeds are already sufficient. For budget-conscious users, a USB 3.2 Gen2 reader might be a more cost-effective choice.
