SD Association Unveils microSD Express Format That Promises Transfer Speeds of Up To 985 MB/s (engadget.com)

The SD Association has unveiled microSD Express, a new format that will bring speeds of up to 985 MB/s to the tiny memory cards used in smartphones and other devices. From a report: Like SD Express, it exploits the NVMe 1.3 and PCIe 3.1 interfaces used in PCs to power high-speed SSDs. The tech is incorporated onto the second row of microSD pins, so the cards will work faster in next-gen devices while maintaining backward compatibility with current microSD tech. PCIe 3.1 allows for low power sub-states, so the cards will not only offer much (much) higher transfer speeds, but consume less power than regular microSD cards. It'll also open up features like bus mastering, which lets memory cards communicate with other components without going through the CPU first.

      This was my first thought as well. It seems to me extending to the PCIe bus to all kinds of untrusted hot plugged devices has bad idea written all over it. USB 2.x we "permissive" enough in terms of memory access.
