The '''XQD card''' is a [[memory card]] format primarily developed for [[flash memory]] cards. It uses [[PCI Express]] as a data transfer interface.
The format is targeted at high-definition [[camcorder]]s and high-resolution digital cameras. It offers target read and write speeds from 1 Gbit/s
The cards are not backward compatible with [[CompactFlash]] or [[CFast]] cards, and despite the name similarity, has no connection with the [[xD-Picture Card]]. XQD and CFast were both designed as a replacement of the
The format was first announced in November 2010 by [[SanDisk]], [[Sony]] and [[Nikon]], and was immediately picked up by the [[CompactFlash Association]] for development.<ref name=engadget_2010>{{cite web|url=https://www.engadget.com/2010/11/30/sandisk-sony-and-nikon-propose-500mb-per-second-memory-card-wi/ |title=Sandisk, Sony, and Nikon propose 500 Mbps memory card with more than 2 TB capacity |

Sony has said their broadcast camcorders ([[XDCAM]] and [[XDCAM EX]]) will support the XQD cards. For their broadcast products the XQD card will be classified as a secondary media as XQD is based around consumer technology.
