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).

So... a wide ranger... that's one that needs a draft horse?

Is this the same UFS that is used in BSDs, or is it a deliberate attempt to name two different things with the same name?
I prefer FFS anyway!

Have you tried coming up with a set of 3-4 letter initials that aren't already in use by a half-dozen or more things? Much less initials that correspond to words even vaguely related to your project? Random unlikely letters just off the top of my head: KRM, XYT, LRQ, MZN - all of them have several different usages showing up on the first page of a Google search.

I've taken to naming everything we design "TLA", to make it easier to remember.

UFS, in this context means Universal Flash Storage

Why do PCs and phones have different storage standards?

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.

Physical size probably. M.2 NVMe is the new PC hotness. The flash in your phone is not replaceable or upgradable. In theory a mobo maker could probably do the same thing? I'd think linux can already talk UFS 3.0.

What is the satandard on PCs? That patented Micro$oft filesystem? I thought that was the standard on mobile.

IDE and SATA mostly, this UFS is a hardware/communication bus specification positioned as an alternative to SD Cards, eMMC, etc., not a file system (there is also filesystem named UFS, but as far as I can tell it's completely unrelated)
