I have an SD card xD It's a 128 GB SD Card because back in 2017 I was told that the Switch could only take SD cards as high as 128. But recently I read an article that stated a company called HyperX or something like that was manufacturing three sizes of card for the Switch, one of them being 256.
And to this day, even though I've asked, I've never been told if the Switch can use a 256 GB SD card or not.
Oh my bad, I mistook you're second post as a reply from OP
