XQD card is a memory card format primarily developed for flash memory cards. It uses PCI Express as a data transfer interface.

The new format is targeted at high-definition camcorders and high-resolution digital cameras. It offers target read and write speeds from 1 Gbit/s (125 Mbyte/s) to about 4 Gbit/s (500 Mbytes/s)[1] and storage capabilities beyond 2 TB.[2]

The cards are not backward compatible with CompactFlash or CFast cards. XQD and CFast were both designed as a replacement of the then-16-year-old (in 2010) CompactFlash standard.

The format was first announced in November 2010 by SanDisk, Sony and Nikon, and was immediately picked up by the CompactFlash Association for development.[3] The final specification was announced in December 2011.[4][1]

XQD version 2.0 was announced in June 2012, featuring support for PCI Express 3.0 with transfer rates up to 8 Gbit/s (1000 Mbyte/s).[5]

Availability

In January 2012, the first XQD card was announced by Sony, declaring a 1 Gbit/s read and write speed.[6][7] In July 2012, Lexar announced plans to support the XQD format.[8] Currently, Sandisk and Kingston have not announced plans to produce XQD cards.[9][10]

Hosts

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. [11]

Nikon supports XQD cards in its newer high-end DSLR cameras: Nikon D4, Nikon D4s, Nikon D5, and Nikon D500.[12][13][14][15]
