Wes Brewer, CEO ProGrade Digital has published a comparison between two emerging memory standards: SD Express and CFexpress.
Recently, the SD Association (governing body for SD card development and standardization) announced finalization of revision 7.0 for the card SD specification. This revision now includes a section 8.0, which adds an NVMe compliant, PCIe interface option. Like the announcement of CFexpress 1.0 made by the CompactFlash Association in August of 2016, the PCIe interface with NVMe provides a scalable path for improved performance in flash-based storage devices, and conforms to industry standards in use for devices such as SSDs.See the ProGrade Digital SD Express vs. CFexpress White Paper for more information.This white paper provides an objective look at variances between the two standards SD Express and CFexpress.
