Purchased for my Nintendo Switch, works perfectly! I originally thought it didn't work because I kept getting an error on my console when I copied my old SD to the new one using my macbook, but apparently the issue was introduced because I used a macbook due to how their files are stored on their SD format. I switched over to Windows, copy/pasted my data from the old to the new and everything just worked like nothing ever happened.
Also, I learned that the Sandisk Ultra is actually faster than the Sandisk Extreme for nintendo switch. this is because the Switch explicitly supports the SDXC-UHS-I. So if you're looking to benefit from the speeds on the UHS-III, you're going to actually lose performance by a 10th of a millisecond.
TL;DR: If you're looking for a SD card for the switch, no matter the capacity, this is the highest performing chip available to you.
