These are denoted by either the number 1 or the number 3 within the letter “U” — usually found somewhere near the Speed Class.

Nikon cameras using XQD include the full-frame flagship pro models D4, D4s, and D5, the ultra high-resolution full-frame pro model D850, the APS-C format professional D500, and the new full-frame mirrorless Z series cameras Z6 and Z7. XQD cards are already offering write speeds of 400MB/s and higher, with an upper limit that isn’t actually known yet for sure, but definitely in the over 1GB/s range – maybe over 2GB/s or higher. That is seriously fast. This means that a photographer won’t be hampered by needing to wait a significant amount of time for their camera buffer to empty out. Therefore, images can be rapidly produced in the camera’s highest resolution.
