Designed for capturing raw 8K, 6K, and 4K video, the 165GB CFexpress 2.0 Type B Cobalt 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 1500 MB/s. Additionally, the Cobalt's minimum write speed is guaranteed not to drop below 1400 MB/s. In addition to raw video, this card can also capture 8K, 6K, and 4K ProRes 4444 video, PreRes 422 HQ video, 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. These cards take advantage of an NVMe host controller interface and backward compatibility with CFexpress 1.0.
