FAQs
Yes, the Switch supports up to 2TB via the SDXC standard. But 256GB hits the value sweet spot for most libraries unless you collect heavily digital.
No, the Switch only reads at UHS-I speeds, so paying for UHS-II is wasted on this console. A solid A1 or A2 rated UHS-I card delivers the maximum the Switch can use.
