UHS-III does not exist! It was proposed as a standard in 2017 but the cards never came to market. Go to any camera store like Adorama or B&H Photo and try to find a UHS-III SD card. You won’t find any. Your only choices are UHS-I and UHS-II.
There are laptops that claim to have UHS-III card readers… but the cards simply do not exist.
I keep hearing reviewers knocking Apple for not having UHS-III card slots in these new Macbooks. But you can’t have something that doesn’t exist.
And to be clear… U3 is not the same as UHS-III. U3 is a shorthand way of saying UHS-II Speed Class 3
SD Express is another forward-looking standard announced in 2018. But there are no cards available nor are there any cameras that can use them today, either.
So basically… the UHS-II slots in these new Macbooks are using the fastest SD card standard. If you use an SD card in your workflow… you’ll be fine.
But don’t complain about a slot when the cards don’t even exist:
