ProGrade Digital Launches More Affordable CFexpress Type A Cards

With the launch of the CFexpress Type A Cobalt, ProGrade Digital has finally given Sony some competition in this market. The new series offers speeds of up to 800 MB/s for read and 700 MB/s for write.

CFexpress Type A memory card formats are smaller than full-size SD and larger than microSD. CFexpress Type A delivers three times the performance of the fastest UHS-II cards by leveraging PCIe Gen 3 interconnect and NVMe 1.3 host control interface.

Sony is the only company that has used the CFexpress Type A specification. Sony can use the same card slot as the more popular and slower SD card slot on Alpha 1 cameras. Sony is the only manufacturer of memory cards to have the slot, and it has been the only camera maker to do so.

ProGrade Digital CFexpress Type A cards offer read speeds of up to 800 MB/s as well as burst writes speeds of up to 700 MB/s. ProGrade Digital’s CFexpress Type A cards offer a minimum sustained write speed (VPG 400), which is designed specifically for high-resolution video capture.

ProGrade Digital spoke with PETaPixel and explained that although Sony is currently the only one using the format, they believe that other manufacturers will soon adopt the open standard.

Wes Brewer, CEO and founder of ProGrade Digital, stated that “Due to CFexpress Type A’s size and performance, we believe next-generation compact DSLRs and mirrorless cameras will adopt this form factor over SD” as he has seen it in some of the new cameras. We are now able offer the most diverse CFexpress cards to suit all current and future imaging needs. Our customers can use our CFexpress Type A USB 3.2 Generation 2 high-speed reader to capture and download still and video images, as well as enhance their digital imaging workflow.

ProGrade Digital will launch a 160 GB card of CFexpress Type A. Starting today, the card will be available at $330
