ProGrade Digital: CFexpress memory card backward compatibility to XQD possible with a firmware update

Yesterday ProGrade Digital announced their new CFexpress 1TB 1400 MB/s memory card. One of the listed benefits of using CFexpress memory cards is the backward compatibility possibility with the XQD format after a firmware update from the camera manufacturer:

  1. Form Factor ideally suited for higher capacities needed in imaging applications – up-to 1TB with current NAND flash memory technology
  2. Physical size that is easy to handle – slightly larger than SD and slightly smaller than CFast or CompactFlash (29.6 x 38.5 x 3.8 mm)
  3. Performance capability capable of >1GB/sec transfer rates, through the use of two PCIe data lanes.
  4. NVMe protocol support for optimized performance with flash memory in newer computing architectures
  5. Backward compatibility possible to XQD host platforms through upgrade of host operating system (firmware)

ProGrade Digital memory cards and card readers are available for sale at Amazon.com and B&H Photo and Video (prices vary from $55 - $700 depending on model and capacity).
