512GB is the comfortable sweet spot for a Switch 2: room for a large library of downloads without constant housekeeping, and the price per gigabyte is often better than the 256GB tier. It must be a microSD Express card, since UHS-I will not run Switch 2 games. This table lists only 512GB microSD Express cards on Amazon.com, ranked by price per gigabyte so the best value is easy to find.
