The Benefits of microSD Express

Описание: SD Association outlines the capabilities of SD Express and microSD Express.

SD Express and microSD Express add the popular PCI Express® and NVMe™ interfaces to SD memory cards alongside the legacy SD interface. 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. All SD Express memory cards are backwards compatible while still benefiting from continued research, development and long-term roadmaps associated with these two architectures. Soon, SD Express memory cards will be able to serve as removable Solid State Drives(SSD).

SD Express ​and microSD Express maintain 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 speeds 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 microSD Express was introduced as part of the SD 7.1 specification. SD Express and microSD Express will be available in SDHC, SDXC and SDUC capacities ranging from plus 2GB to 128 TB.
