Why would anybody adopt a newer standard with no backwards compatibility and slower speeds?
What could even warrant "high speeds" from a damned phone? I can't think of a single thing that would tax an SD card that I'd be doing on a phone.
video recording/editing (some phones can record 4k at high frame rates) , gaming, general responsiveness. I know that we as tech (and especially linux) people don't really understand that but a lot of people are using their phones for a whole load of things now and especially with things now. Also the argument why you would choose UFS would be higher speeds. The real argument for MicroSD Express is backwards compatibility.
Also also I'm looking forwards to being able to run SBC from a MicroSD Express card so it's at least somewhat faster.
They are still a lot faster than normal SD cards. I've never seen any phone that works with SD Express cards, but there were a few that worked with UFS cards.
If you are a phone manufacturer you can either choose MicroSD cards which are the most common and the cheapest, MicroSD Express Cards which are more expensive but faster and backwards compatible or UFS which nobody has ever heard of.
