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 camcorders and high-resolution digital cameras. It offers target read and write speeds from 1 Gbit/s to about 5 Gbit/s and storage capabilities beyond 2 TiB.{{cite web|url=http://compactflash.org/2011/compactflash-association-announces-the-recently-adopted-xqdtm-specification-as-a-new-memory-card-format/ |date=7 December 2011 |access-date=17 January 2012 |publisher=CompactFlash Association |title=CompactFlash Association Announces the Recently Adopted XQD(TM) Specification as a New Memory Card Format |quote=Actual Write Speeds Target 125 MB/sec and Higher |url-status=dead|archive-url=https://web.archive.org/web/20120125110714/http://compactflash.org/2011/compactflash-association-announces-the-recently-adopted-xqdtm-specification-as-a-new-memory-card-format/ |archive-date=January 25, 2012 }}{{cite web |title=What is XQD and Why Should I use it {{!}} Nikon |url=https://www.nikonusa.com/en/learn-and-explore/a/products-and-innovation/what-is-xqd-and-why-should-i-use-it.html |access-date=2023-04-29 |website=www.nikonusa.com |language=en}}{{Failed verification|date=April 2023}}
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 1994 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.{{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 |date=November 30, 2010 |publisher=Engadget |access-date=2012-09-19}} The final specification was announced in December 2011.{{cite web|url=https://www.engadget.com/2011/12/08/compactflash-association-readies-next-gen-xqd-format-promises-w/ |title=CompactFlash Association readies next-gen XQD format, promises write speeds of 125 MB/s and up |date=December 8, 2011 |publisher=Engadget |access-date=2012-09-19}}{{cite web|url=http://compactflash.org/2011/compactflash-association-announces-the-recently-adopted-xqdtm-specification-as-a-new-memory-card-format/ |title=CompactFlash Association Announces XQD Card Format |publisher=Compactflash.org |date=2011-12-07 |access-date=2012-09-19 |url-status=dead|archive-url=https://web.archive.org/web/20120929063750/http://compactflash.org/2011/compactflash-association-announces-the-recently-adopted-xqdtm-specification-as-a-new-memory-card-format/ |archive-date=September 29, 2012 }}
XQD version 2.0 was announced in June 2012, featuring support for PCI Express 3.0 with transfer rates up to 8 Gbit/s (1 GB/s).{{cite web|url=http://compactflash.org/2012/the-compactflash-association-invites-participation-on-xqdtm-2-0/ |title=The CompactFlash Association Invites Participation on XQDTM 2.0 — The CompactFlash Association |publisher=Compactflash.org |date=2012-09-15 |access-date=2012-09-19 |url-status=dead|archive-url=https://web.archive.org/web/20120919014523/http://compactflash.org/2012/the-compactflash-association-invites-participation-on-xqdtm-2-0/ |archive-date=September 19, 2012}}
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.
Support
In January 2012, the first XQD card was announced by Sony, declaring a 1 Gbit/s read and write speed.{{cite web |url=https://techcrunch.com/2012/01/06/sony-xqd-memory-cards/ |title=Sony Announces World's First XQD Memory Cards |date=6 January 2012 |access-date=2012-01-08}}{{cite web|url=http://presscentre.sony.co.uk/content/detail.aspx?NewsAreaId%3D2%26ReleaseID%3D7201 |title=Sony - Sony unveils new high-speed XQD™*1 memory cards : : News : Sony Europe Press Centre |access-date=March 12, 2013 |url-status=dead|archive-url=https://web.archive.org/web/20140308000937/http://presscentre.sony.co.uk/content/detail.aspx?NewsAreaId=2&ReleaseID=7201 |archive-date=March 8, 2014 }} In July 2012, Lexar (owned at the time by Micron) announced plans to support the XQD format.{{cite web |url=http://www.lexar.com/about/newsroom/press-releases/lexar-announces-support-xqd-memory-card-specification |title=Lexar Announces Support for XQD Memory Card Specification |access-date=2012-07-12}}
As of 2012, SanDisk and Kingston had not announced plans to produce XQD cards.{{cite web |url=http://www.techradar.com/news/photography-video-capture/cameras/sandisk-lexar-kingston-not-making-new-xqd-cards-1055347 |title=Sandisk, Lexar, Kingston not making new XQD cards |date=17 January 2012 |access-date=2012-01-25}}{{cite web |url=http://ces.cnet.com/8301-33363_1-57358446/sandisk-on-new-xqd-memory-card-format-meh/ |title=SanDisk on new XQD memory card format: 'Meh' |first=Stephen |last=Shankland |publisher=CNET |date=2012-01-13 |access-date=2012-01-25 |archive-date=January 14, 2012 |archive-url=https://web.archive.org/web/20120114034600/http://ces.cnet.com/8301-33363_1-57358446/sandisk-on-new-xqd-memory-card-format-meh/ |url-status=dead }}
In addition to Sony, as of August 2018, Nikon and Delkin are also manufacturing XQD cards.{{Citation needed|date=July 2019}}
In late 2018, Lexar – by then under new ownership – announced that it would discontinue support for the XQD format in favour of CFexpress, citing problems with control, licensing and product availability.
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.{{cite web |url=http://pro.sony.com/bbsc/ssr/micro-xdcam/resource.latest.bbsccms-assets-micro-xdcam-latest-pxwz100.shtml?PID=I:prohomepage:promotion:pxwz100_landing_page? |title=Sony XDCAM Micro site |publisher=Sony |date=2013-09-04|access-date=2013-09-03}} Additionally, Sony’s PXW-FS7 and PXW-FX9 cameras also support XQD cards.
Nikon supports XQD cards in its newer high-end DSLR and mirrorless cameras: Nikon D4, Nikon D4s, Nikon D5, Nikon D6, Nikon D850, Nikon D500 and Nikon Z6 & Nikon Z7.{{cite web |url= https://arstechnica.com/gadgets/news/2012/01/nikon-d4-first-camera-to-use-new-xqd-cards-sony-to-make-them.ars |title=Nikon announces first camera to use new XQD cards |work=arstechnica.com |year=2012|access-date=2012-01-07}}{{cite press release|url=http://press.nikonusa.com/post/2012/01/05/when-there-is-no-second-chance-the-new-nikon-fx-format-d4-multi-media-digital-slr-is-the-definitive-unification-of-speed-and-precision/ |title=When There Is No Second Chance: The New Nikon FX-Format D4 Multi-Media Digital SLR is The Definitive Unification Of Speed And Precision |publisher=Nikon Inc. |year=2012 |access-date=2012-01-07 |url-status=dead|archive-url=https://web.archive.org/web/20120108074659/http://press.nikonusa.com/post/2012/01/05/when-there-is-no-second-chance-the-new-nikon-fx-format-d4-multi-media-digital-slr-is-the-definitive-unification-of-speed-and-precision/ |archive-date=January 8, 2012 }}{{cite press release|url=http://www.nikonusa.com/en/about-nikon/press-room/press-release/iihiz19a/Conquer-the-Dark%3A-The-New-Nikon-D5-DSLR-Shatters-Expectations-for-Thrilling-New-Levels-of-Low-Light-Performance,-Image-Quality-and-Speed.html/ |title=Conquer the Dark: The New Nikon D5 DSLR Shatters Expectations for Thrilling New Levels of Low-Light Performance, Image Quality and Speed |publisher=Nikon Inc. |year=2016 |access-date=2016-01-05 |url-status=dead|archive-url=https://web.archive.org/web/20160107225345/http://www.nikonusa.com/en/about-nikon/press-room/press-release/iihiz19a/Conquer-the-Dark:-The-New-Nikon-D5-DSLR-Shatters-Expectations-for-Thrilling-New-Levels-of-Low-Light-Performance,-Image-Quality-and-Speed.html |archive-date=January 7, 2016 }}{{cite press release|url=http://www.nikonusa.com/en/about-nikon/press-room/press-release/iihiz234/Pro-Pedigree,-DX-Agility%3A-The-New-Nikon-D500-Establishes-a-New-Era-of-DX-Format-Performance.html/ |title=Pro Pedigree, DX Agility: The New Nikon D500 Establishes a New Era of DX-Format Performance |publisher=Nikon Inc. |year=2016 |access-date=2016-01-05 |url-status=dead|archive-url=https://web.archive.org/web/20160107211826/http://www.nikonusa.com/en/about-nikon/press-room/press-release/iihiz234/Pro-Pedigree,-DX-Agility:-The-New-Nikon-D500-Establishes-a-New-Era-of-DX-Format-Performance.html |archive-date=January 7, 2016 }}
