ProGrade Digital Announces Faster CFexpress Type B Memory Cards and Higher Capacities with Read Speeds of 1,700MB/s

ProGrade Digital, Inc., founded with a mission to provide the highest quality professional grade digital memory cards and workflow solutions, announces its new CFexpress Type B cards. First demonstrated by the company in April 2018 at the National Association of Broadcasters Show (NAB) Las Vegas, CFexpress Type B offers next-generation memory card performance by leveraging PCIe, Gen 3 interconnect with NVMe 1.3 host controller interface.

ProGrade Digital CFexpress cards provide read speeds up to 1,700MB/s, and burst write speeds up to 1,500MB/s. Two performance levels are available: Cobalt label: delivers a minimum sustained write speed of 1400MB/s for both 325GB and 650GB cards – specifically designed for high-resolution video capture and long, sustained burst image capture applications; Gold label: delivers a minimum sustained write speeds up to 400MB/s depending on card capacity – ideally suited for a broad range of still and moving image capture applications.

“Since demonstrating the capabilities of CFexpress in early 2018, ProGrade Digital has been evolving this technology from the first cards introduced at the end of 2019 to these new, faster and lower power cards we are shipping today,” said Wes Brewer, founder, and CEO of ProGrade Digital. “We are now able to offer the widest range of CFexpress card choices to meet both current and future needs of all leading-edge imaging applications. Coupled with our new CFexpress Thunderbolt 3 and USB 3.2 Gen 2 high-speed readers and our Refresh Pro performance restoration and health monitoring software application, our customers have a complete solution for capturing and downloading still and video images as well as enhancing their digital imaging workflow.”
