I also have that same 400GB Sandisk MicroSD card inside my Switch, and it works perfectly fine. My own benchmark shows a 95MB read and over 50MB write, which means it’s more than enough for Switch’s internal SD reader. So don’t overspend by purchasing the Extreme/Pro/Elite variants of these MicroSD cards as your Switch’s bus reader cannot take advantage of of the extra performance provided by those higher-end Micro SD cards.
Do realise though that this same card was priced at less than $45 in the US around less than a month ago during Prime Day, and I suspect it will go even lower during Blackfriday week in the US. So if you’re not in rush, then I’d say it might be better to wait until then.
