Large Capacity CFexpress Type B Media for Advanced Video Production Our largest capacity CFexpress Type B card is 1 TB for capturing the highest bit-rate RAW video and photo files at 6K, 8K, and 12K+ resolutions. Engineered for maximum sustained high-speed recording with video and photo cameras. The AV PRO CFexpress MK2 Type B card ensures the highest quality data capture throughout the capacity of the card with no throttling of performance and a guaranteed minimum sustained speed of 1300 MB/s throughout the entire capacity of the card. Our CFexpress Type B card relies on the Angelbird Y2 super-processor designed specifically for RAW photo and video content creation and is designed to protect against overheating and to operate at a reduced power draw. Stable Stream Sustained Write Performance Capturing detailed, high-definition frames requires a sustained write speed that does not throttle or drop off in performance as the capacity of the card gets used. Our Stable Stream technology supports uninterrupted read and write performance for smooth, drop-free results throughout the entire capacity of the card. Our AV PRO CFexpress MK2 features a Stable Stream sustained write performance range with a minimum write speed of 1300 MB/s and a max write speed of 1550 MB/s.
