The new format is targeted at high-definition camcorders and high-resolution digital photo cameras. It offers target read and write speeds from 1 Gbit/s (125 Mbyte/s) to about 4 Gbit/s (500 Mbytes/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. Currently, Sandisk and Kingston have not announced plans to produce XQD cards
Sony has also 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 a DSLR consumer technology, however, the cards will support acquisition in the broadcast quality MPEG HD422 50 Mbit/s. On 4 September 2013, they released the PXW-Z100, a 4K prosumer camera that records onto XQD cards.
