The world of memory and storage technology is constantly evolving, and new advancements are being made each year. One such innovation is SD Express, which offers a broader range of benefits and advantages that are propelling storage technology forward.
SD Express is a next-generation bus feature available for full-sized and microSD memory cards that combines the existing SD interface with PCIe® and NVMe™ architectures. This allows for SSD-like data transfer speeds supported by the PCIe interface as well as improved power efficiency and more efficient storage utilization using the NVMe protocol. As the card’s capacities constantly increase – like the recently announced 1.5TB and 2TB cards, the advantage of the SD Express high speed may be even more valuable. The SD9.0 and SD9.1 specifications bring several new capabilities to the table, including enhanced security (self-encrypted Drive using TCG and Replay Protected Memory Block mechanism) and secure boot options. These features make SD Express an attractive choice for a wide range of new devices, including smartphones, cameras of all types, virtual and augmented reality, IoT devices and much, much more.
