On 4 September 2013, Sony released the PXW-Z100, a 4K prosumer camera that records onto XQD cards. Nonetheless, the cards will support acquisition in the broadcast quality MPEG HD422 50 Mbit/s format. For their broadcast products the XQD card will be classified as a secondary media as XQD is based around consumer technology. Sony has said their broadcast camcorders ( XDCAM and XDCAM EX) will support the XQD cards. 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. In addition to Sony, as of August 2018, Nikon and Delkin are also manufacturing XQD cards. Īs of 2012, SanDisk and Kingston had not announced plans to produce XQD cards. In July 2012, Lexar (owned at the time by Micron) announced plans to support the XQD format. In January 2012, the first XQD card was announced by Sony, declaring a 1 Gbit/s read and write speed.
This new standard uses the same form-factor and interface but uses the NVMe protocol for higher speeds, lower latencies and lower power consumption.
On 7 September 2016 the CFA announced the successor of XQD, CFexpress. 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). The final specification was announced in December 2011. The format was first announced in November 2010 by SanDisk, Sony and Nikon, and was immediately picked up by the CompactFlash Association for development. XQD and CFast were both designed as a replacement of the 1994 CompactFlash standard. The cards are not backward compatible with CompactFlash or CFast cards, and despite the name similarity, has no connection with the xD-Picture Card. 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 is targeted at high-definition camcorders and high-resolution digital cameras. It uses PCI Express as a data transfer interface. The XQD card is a memory card format primarily developed for flash memory cards.
