The Lexar 512GB microSD Express card adds storage for the Nintendo Switch 2, which accepts only microSD Express cards and not ordinary microSD cards. It gives you 512GB of room for downloaded games, updates and captures, in the microSDXC Express format that Lexar lists for the Switch 2. The card is IPX7 water resistant and built to cope with shocks, drops, vibration, magnets and airport X-ray exposure. It also works in devices with a standard UHS-I slot, but only at UHS-I speeds, since top speeds need a microSD Express host. This is a new, sealed microSD Express card.
