JEDEC has published UFS 3.0, which will double the bandwidth available to smartphones and other devices, and specifies temperature event notifications intended for automotive storage applications:

Smartphones already have storage speeds that rival PCs and they're going to take another big leap soon. Standards group JEDEC has unveiled UFS 3.0, a new flash storage standard for mobile devices, Chromebooks, VR headsets and automotive devices that doubles the bandwidth of UFS 2.1 to a stellar 2.9 GB/s. That's only a theoretical maximum that real-world devices won't likely reach, however, and requires that the host device has the hardware to support it.

UFS 3.0 also lowers flash power consumption and increases reliability in a [wider range] of temperature conditions, a bonus for vehicle applications. It does all this thanks to lower voltage requirements that support the latest types of NAND, a refresh function that increases reliability, and double the speeds per lane (from 5.8 to 11.6 Gbps with a maximum of two lanes).

    At a guess, spinning discs versus flash. Virtually all PC standards were designed around the very different characteristics of spinning-disc interfaces. Phones *never* use spinning discs, and thus present an excellent opportunity to discard legacy standards and design something around the characteristics of flash. Meanwhile legacy flash standards (CompactFlash, SD, etc.) were designed with very different use-cases and performance characteristics of media recording in mind, and aren't a particularly good fit for the far more active pseudo-random I/O typical of aa modern computer's primary drive.
