XQD is a media card format that was designed to be a successor to the CompactFlash card. XQD has been adopted by Nikon and was first incorporated into the D4 and D4S and subsequently into the D5, D500 and D850 DSLRs and Z 7 and Z 6 full-frame mirrorless cameras. The XQD format is designed to take advantage of the speed that these cameras can offer photographers.

Recording to XQD, the D5 can shoot up to 200 shots...
