PetaPixel tested those cards and wrote:
To get a sense of how fast read and write speeds performed at peak individually, the Lexar CFexpress Type A card was run through Blackmagic Disk Speed test, which returned 719 MB/s write speed average and 729.7 MB/s read speed average.
For comparison, in previous tests the Sony TOUGH CFexpress Type A memory card averaged about 651 MB/s write speeds and 731 MB/s read speeds while the ProGrade Digital CFexpress Type A card averaged 679 MB/s write speeds and 784 MB/s read speeds. The new Lexar shows faster write speeds but slower read speeds.
In HD Tune, the Sony TOUGH card scored a minimum transfer speed of 431.9 MB/s and a maximum of 559.4 MB/s, for an average of 532.4 MB/s. ProGrade Digital’s card scored a minimum transfer speed of 416 MB/s and a maximum of 548.8 MB/s, for an average of 516 MB/s. Both were tested using their own company’s memory card readers and both are behind Lexar’s sustained read and write performance by a significant margin.
