Designed for emerging mainstream imaging applications, the 512GB CFexpress 2.0 Type B Gold Memory Card from ProGrade Digital provides read speeds of up to 1700 MB/s, which helps to quickly offload content to your computer, and write speeds of up to 1400 MB/s. Additionally, the Gold’s minimum write speed is guaranteed not to drop below 300 MB/s, which allows for the uninterrupted recording of a wide variety of codecs, including raw 4K video, 4K and 6K ProRes 4444, 4K, 6K, and 8K ProRes 422 HQ, and more. This card is resistant to temperature extremes, shock, vibration, and X-rays, and is also backward compatible with select XQD cameras that adopt firmware to enable CFexpress. This card also takes advantage of an NVMe host controller interface and backward compatibility with CFexpress 1.0.
