Higher Performance CFexpress 4.0 Type A Memory Cards with CFexpress Type A Single-Slot USB 4.0 Reader Enables a Faster Workflow

San Jose, CA April 12, 2024, 8:00 am —ProGrade Digital, Inc., founded with a mission to provide the highest quality professional grade digital memory cards and workflow solutions, announces its new line of higher capacity CFexpress 4.0 Type A, VPG200 memory cards in the Iridium product line. These higher-performance cards offer a read speed of up to 1800MB/s, write speed of up to 1700MB/s, and sustained write speeds of 800MB/s and 1450MB/s respectively, enabling the capture of even longer clips of high-resolution video and/or greater amounts of still images. ProGrade Digital CFexpress Type A Iridium cards bring high performance to cinema, DSLRs, and mirrorless cameras, which produce incredibly rich data streams and require greater capacity from a memory card.

“The introduction of our new CFexpress Type A, Iridium line of memory cards – with capacities of 480GB and 960GB – provide high-capacity storage levels at a competitive price to meet the needs of high-performance still and video shooters,” said Josh Brewer, Product Manager of ProGrade Digital. “This new range of cards for ProGrade combines the necessary VPG 200 levels of video performance, with the recently created CFexpress 4.0 standard for the fastest read and write speeds and highest levels of reliability.”

In conjunction with the Type A Iridium cards, ProGrade Digital is proud to announce its new USB 4.0 card reader, a single-slot card reader designed specifically for the latest CFexpress 4.0 (PCIe Gen 4) Type A memory cards. The PG09.6 reader is based on the latest USB 4.0 technology which is designed to achieve speeds of up to 40Gb/s. The PG09.6 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 for maximum performance. The PG09.6 is compatible with Thunderbolt™ 4 and Thunderbolt™ 3 ports.

“Our new PG09.6 reader provides a tremendous leap forward in Type A workflow performance by allowing content offload speeds to be reduced by 67% when compared to the performance of our USB 3.2, Gen 2-enabled readers”, said Josh Brewer, Product Manager 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.”

The CFexpress 4.0 Type A Iridium memory cards and PG09.6 will be available for purchase in early May.
