The format is targeted at high-definition camcorders and high-resolution digital cameras. It offers target read and write speeds from 1 Gbit/s (0.125 GB/s) to about 4 Gbit/s (0.5 GB/s) and storage capabilities beyond 2 TB.
The format was first announced in November 2010 by SanDisk, Sony and Nikon, and was immediately picked up by the CompactFlash Association for development. The final specification was announced in December 2011.
In January 2012, the first XQD card was announced by Sony, declaring a 1 Gbit/s read and write speed. In July 2012, Lexar announced plans to support the XQD format. In June 2017, Micron announced it was discontinuing the Lexar brand. In addition to Sony, as of August 2018, Nikon and Delkin are also manufacturing XQD cards. As of 2012, SanDisk and Kingston had not announced plans to produce XQD cards.
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. Nonetheless, the cards will support acquisition in the broadcast quality MPEG HD422 50 Mbit/s format. On 4 September 2013, Sony released the PXW-Z100, a 4K prosumer camera that records onto XQD cards.
On 7 September 2016 the CFA announced the successor of XQD, CFexpress. This new standard uses the same form-factor and interface but uses the NVMe protocol for higher speeds, lower latencies and lower power consumption.
