Ultra High-Speed Media Format. With the ProGrade Digital 512GB CFexpress 4.0 Gold 3400 MB/s Type B memory card, you’re provided with a maximum read speed of 3400 MB/s, a max write speed of 3000 MB/s, and a minimum write speed of 2400 MB/s. This specific card stands out in its pack, since these high read and write speeds are nearly unheard of in the Type B card world.

Extremely Low Latency. This card’s ultra-fast write speed ensures extremely low latency, making it ideal for the uninterrupted recording of a wide variety of codecs, including 8K, 6K, 4K ProRes 4444 video, ProRes 422 HQ video, and more.

XQD Compatibility. The CFexpress Type B media format uses the same form-factor as the XQD format. This means CFexpress cards may work in compatible XQD cameras that have updated firmware to support the CFexpress format.

More Storage? We have a 1TB version of this card available that holds the same speedy read and write speeds!
