The SD Association has announced its newest memory card type. Similar to the previously revealed SD Express format, the upcoming microSD Express format uses the PCIe interface and NVMe upper layer protocol to enable faster data transfer speeds and advanced memory access.

"microSD Express gives the mobile industry a compelling new choice to equip mobile devices with removable SSDs," said Hiroyuki Sakamoto, SDA president. "SD 7.1 prepares consumers and mobile device manufacturers to meet ever increasing storage demands for years to come."

The microSD Express format is capable of up to a 985 MB/sec transfer rate, along with backwards compatibility. Under the SD 7.1 specification, cards will be available in several capacities, including microSDHC Express, microSDXC Express, and microSDUC Express. And in addition to superior speeds, microSD Express cards are also set to consume less power than typical microSD memory cards.


"NVMe is the industry-recognized performance SSD interface from the client to the data center to mobile, shipping in millions of units," said Amber Huffman, NVM Express® Inc. president. "By SDA adopting NVMe technology into the new microSD Express cards, users can experience lower latency and increasingly fast transfer speeds across various applications."

Pricing and availability for the first microSD Express cards have not been announced yet. Likewise, no microSD Express compatible devices have been revealed -- but the tech's advantages should be useful for high resolution mobile videos, action camera recording, 360-degree videos, VR, data-intense wireless communication, gaming consoles, multi-channel IoT devices, automotive products, and more.
