The SD Association (SDA) recently announced SD Express, which adds the PCI Express^® and NVMe™ interfaces to the SD interface. The PCIe^® interface delivers transfer rates up to 985 megabytes per second (MB/s) and supports backward compatibility with existing SD hosts.

This is already shaping up to be a busy year for PCI-SIG^® with the pending release of the PCI Express^® 5.0 specification targete

PCI Express (PCIe^®) has been widely adopted in a number of applications that range from small, power-constrained IoT sensors and mobile devices to servers and networking and communications equipment.
