The Best CFexpress Type B Card in 2023 Of note, PetaPixel did notice that a few cards took longer to recover than others.

The decision allowed Nikon to save some face by creating firmware that allowed their XQD cameras to work with much faster and cheaper CFexpress cards. At the same time, other manufacturers who had been investigating the use of XQD could make a straight switch CFexpress Type B instead.
