MicroSD Express unlocks hyper-fast data speeds for mobile devices


See the SD Express section in this Wikipedia section. I can't be bothered to enable enough tracking to get engadget to load these days.

I'd be tempted to say this is largely irrelevant for ARM cores, since PCIe tends to be implemeted by the northbridge (which tends to have been implemented inside the CPU package these days), but there have been ARM cores that support it in the past, so it's presumably not impossible. Some of the Marvell cores apparently did, and ARM's website lists a new core for 2015 that supports it too. That latter one is definitely designed for arm servers though, I think. But it presumably means that implementation of the bus exist, so could be brought to lower power chips to an extent. Having to run a 2.5GHz clock or thereabouts for it will limit just how low it can go though.
 
I've never seen a reader or any device supporting UHS-II or anything that has more pins than the old standard.
As long as they need more pins it won't become mainstream in my opinion.
