SD Express - Revolutionary Innovation for SD Memory Cards
The SD Association introduces the revolutionary capabilities of SD Express.
SD Express adds the popular PCI Express® and NVMe™ interfaces The PCIe interface delivers a 985 megabytes per second (MB/s) maximum data transfer rate and the NVMe upper layer protocol enables advanced memory access mechanism. SD Express memory cards can soon serve as removable Solid State Drives(SSD).
SD Express maintains the long-standing advantage of SD’s backward compatibility and interoperability. The PCIe interface was added, in addition to the existing SD (UHS-I) interface, allowing a card with SD Express to operate interchangeably in new SD Express capable hosts as well as with billions of existing SD host products in the market today.
The speeds delivered by SD Express are essential for high-resolution content applications such as: super-slow motion video, RAW continuous burst mode photography, 8K video capture and playback, 360-degree photo, 360-degree video, virtual reality (VR). The high speed capabilities are also essential with speed hungry applications running on cards and mobile computing devices, ever-evolving gaming systems, multi-channel Internet-Of-Things (IoT) devices, numerous automotive storage needs, and other applications that require high performance removable memory cards.
SD Express was introduced as part of the SD 7.0 specification and will be available in SDHC, SDXC and SDUC capacities ranging from over 2GB to 128 TB.
