Designed for high resolution cinema-grade video capture applications, the 240GB CFexpress 2.0 Type A Gold Memory Card (2-Pack) from ProGrade Digital uses an NVMe PCIe 3.0 x1 interface to provide read speeds of up to 900 MB/s, write speeds of up to 800 MB/s, and sustained write speeds of 600 MB/s. Additionally, thanks to the VPG-200 spec, the Gold's minimum write speed is guaranteed not to drop below 200 MB/s. This card is resistant to shock, X-rays, and temperatures ranging from 14 to 158°F. Built-in thermal throttling helps keep the card cool during operations and laser-etched serial numbers help track key components and manufacturing data for improved quality control.
