UHS-II cards can be used in UHS-I systems. The key takeaway here is that after heavy usage, it might be better to move the card to read-heavy usage scenarios.
You can't just wipe it it start to end with zeros, like you do with an SSD that doesn't support TRIM?
I'd point out that these cards have become fast enough and large enough (especially SD cards) that IF your computer supports UHS-II, it's kinda nice to just plug in a 500GB card and leave it there, as a "fast enough" extra 500GB of storage that's small enough that you barely notice it (ie rather smaller footprint than connecting a USB drive). I do wonder the extent to which this usage model will grow. Cards used to be too small and slow to compete in this way, but not the current crop. Sure, they're slower than a high-end SSD, but, like I said, for so many purposes they're fast enough, and even more convenient than a USB3 SSD.
How many computers support UHS-II though? Or are you just talking about laptops and NUC like devices? If so, then how many of those have the cards sunk in deep enough to not worry about it? I know a lot of my laptops had the cards sticking half way out, not really being an ideal solution to anything. And prices are high enough (150€ for 256GB and over 400€ for 512GB). Unless you are already maxed with your internal M.2 or SATA storage, you can get 1TB SSDs for the price of one 256GB UHS-II card.

UHS-II is not supported by the Switch, if I am not mistaken?ganeshts - Tuesday, November 20, 2018 - link

This number seems to be an error: "The reads remain rock-solid at 70 MBps."
