SanDisk, Canon and ARRI decided to back CFast 2 instead. By mid-2013 it was pretty clear that XQD 2 as originally proposed was dead-on-arrival. The XQD 2 standard was supposed to be finalized in the Fall of 2012. The planned technical revision was to replace PCIe 2 with PCIe 3. XQD 2 was announced in the summer of 2012. These 12 companies formed the CF Association to takeover stewardship of the CF standard.Īs a comparison, four years after XQD was first announced in 2010, only Nikon and Sony have cameras using the format. Within one year of its announcement, CF was backed by 12 major companies, including Apple, Canon, Kodak, HP, Panasonic, Polaroid, Seagate and SanDisk. I.e., there is a possibility that XQD 1 cards may only work in some (but not all) XQD 2 cameras / devices.ĬF's adoption was one of the fastest in the history of consumer electronics, especially considering that CF was a proprietary SanDisk format at the time.

Lastly, from what's been announced so far, it's not clear to me that they've preserved full "forward compatibility" of XQD 1. Otherwise I think we will continue to see a split between CF / CFast / XQD adoptees. Hopefully these concessions are enough to convince other camera / device manufacturers to support XQD. And it looks like they've made some other concessions, such USB 3 compatibility, which has a "realistic" transfer speed of only 400 MB/s. Most notably, the XQD 2 spec will now be based on the older PCIe 2 standard (vs. Here are a couple posts on our sister site from way back in 2012:Īnd looks like they've actually "downgraded" the XQD 2 spec a bit vs. XQD 2 spec is actually two years late, which tells us something about XQD's adoption.
