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:
- Form Factor ideally suited for higher capacities needed in imaging applications – up-to 1TB with current NAND flash memory technology
- 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)
- Performance capability capable of >1GB/sec transfer rates, through the use of two PCIe data lanes.
- NVMe protocol support for optimized performance with flash memory in newer computing architectures
- 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).
