Data Transfer Rate Capability of up to 40Gbps Allows Users of CFexpress Type B Devices to Triple Their Current Workflow Performance

San Jose, CA September 5, 2023, 8:00 ET —ProGrade Digital™, founded with a mission to provide the highest quality professional grade digital memory cards and workflow solutions, announces its new PG05.6 card reader, a single-slot reader designed specifically for the latest CFexpress 4.0 (PCIe Gen 4) Type B memory cards. The PG05.6 reader is based on the latest USB 4.0 technology which is designed to achieve speeds of up to 40Gbits/sec. When used in conjunction with the latest CFexpress 4.0 (PCIe Gen 4) memory cards, benchmark tests highlight a tripling of data transfer speed from card to host. The PG05.6 is also equipped with ProGrade’s patented magnetic base and an adhesive metal plate that allows users to mount the reader to any work surface, such as the back of a laptop. The new reader is also supplied with a certified USB 4.0 cable – assuring the maximum performance possible.

“Our new PG05.6 reader provides a tremendous leap forward in workflow performance by allowing content offload speeds to be reduced by 67% when compared to the performance of USB 3.2, Gen 2 technology of our current product line-up”, said Wes Brewer, CEO and Founder of ProGrade Digital. “Along with faster speeds comes the need to provide extra cooling capability for reader and card – something we’ve spent more than a year perfecting in the new design.”
