"The CFexpress standard has been evolving for several years within the CompactFlash Association as a successor to both CFast and XQD formats. We are pleased to be working within the CFA and aside device manufacturers to bring to market this next generation removable storage standard, industry adoption of CFexpress will allow for much higher resolution and higher bit rate image capture than ever before in many still image and video capture devices. Faster offload speeds will also greatly benefit the post-capture workflow through the extremely high read speeds it provides. With our demonstration today, we've also been able to show compatibility for the CFexpress Type B form factor with XQD memory cards-showing operation of both card standards in a common Thunderbolt 3 reader."
