Yes. An original Nintendo Switch can use a microSD Express card, but it reads and writes data at standard microSD-card speed. Express is useful if you also need the card for a Switch 2; it is not a speed upgrade for the original console.

What happens when you use an Express card in the original Switch?

Nintendo lists microSD Express as compatible with the original Nintendo Switch. The console does not take advantage of Express speeds: Nintendo says the card’s data-reading and writing speed on a Switch is equivalent to that of a standard microSD card. Nintendo’s compatibility guidance therefore supports using the card, but not expecting faster game loading or transfers on this hardware.
