The Lexar 2933X is last an only XQD memory card by Lexar. It’s rated for read speed of about 440MB/s, although expect to see much slower speeds if you’re using USB 3.0 memory card readers and don’t expect to see that kind of speed in any modern camera. For example the Nikon D850 only writes to this card at a speed of 113.84 MB/s.
The XQD cards are much larger than SD memory cards but also much smaller than CFast cards. They strike a great balance between size and incredible speed.
