Really? Is there any need for this in gaming? I use some high end microSD card for cameras to keep up when trying to quickly write high rez and high frame rate videos to the card. Most games are only going to be reading from disk...
Main problem is Switch cards are limited by the UHS-I compatibility. Would be nice for a Switch revision to support faster cards.
It supports UHS-I up to 95MB/s transfer rates so this would work.
What I don't get is the big deal on this particular microSD card. It has 100/80MB/s. So I can buy a 256GB Samsung Evo+ on Amazon for $95 bucks and it is 95/90MB/s. Or for the same price I can buy 2 256GB Evo+ cards.
Patriot has a 256GB with 95/85MB/s on Newegg for $80 bucks.
So you can drop performance slightly, so slightly that you may never notice since the majority of files will be photos and music files, and cut the price in half or even less? Who is going to pay double the price for a product that is not superior? I would go with Samsung over this easily.
