A few days ago Angelbird announced their first CFexpress memory cards that offer read speeds of up to 1700MB/sec and write speeds of up to 1400MB/sec:
“The AV PRO CFX is best suited for production work that requires a minimum guaranteed write speed of 550 MB/s, a recording speed still well above the current XQD-400 standard of 400 MB/sec, with capacities of up to 1 TB. Creative professionals working at the leading edge of digital production will find that the CFexpress memory card is the ideal media for content production that demands 4k and 6K+ resolution.
The AV PRO CFX XT is the best rock-solid option for optimal sustained write performance. With its 1 GB/s sustained write speeds the 4-6-8K resolutions will be able to be captured uncompressed RAW. The AV PRO CFX XT is ideal for high-capacity frame rate capture needs with data capacities up to 640 GB.”
Angelbird memory cards are sold at Adorama, B&H and Amazon.
