What is SD UHS II?

UHS-I vs UHS-II on microSD and SD Cards. If you've looked at buying an SD or microSD card lately, you might have run into some new codes: specifically, UHS-II. It refers to something called ultra high-speed bus, which in turn refers to the interface between the card and the device.

Considering this, what is the difference between UHS I and UHS II?

UHS-II cards offer faster read and write speeds and are designed for videographers who need to write and back up large capacities of data. UHS-I cards provide slower speeds but are far cheaper to buy. These are designed mainly for stills shooters.

Why are UHS II cards so expensive?

UHS-II SD cards are expensive - in fact they costs more than the fastest XQD and are slower to boot! But UHS-I SD cards are cheap - the fastest at 95 MB/s isn't that expensive. Just because the new cameras have UHS-II slots doesn't mean you NEED to use them - I have been using UHS-I cards without any problems.
