Product details
The officially licensed storage fix for a Nintendo Switch that's out of room. This 128GB microSDXC is designed, tested, and approved for Switch consoles, with up to 100MB/s reads and 90MB/s writes so eShop downloads and updates land quickly and games load smoothly. It's the straightforward capacity bump for a growing digital library — no settings to tweak, no compatibility guessing — and a lifetime limited warranty means it's the last card your Switch will need for a long while.
The search this answers is simply "Nintendo Switch memory card" or "Switch microSD 128GB." This is SanDisk's Nintendo-licensed line — designed, tested, and approved for the Switch family — so compatibility is guaranteed by the two companies whose names are on the box, not by a forum thread. For a mostly-physical collector who downloads some eShop titles, demos, and updates, 128GB is the sensible first expansion.
Performance is matched to the console: up to 100MB/s reads and 90MB/s writes over UHS-I with a U3 rating, which is the speed envelope the Switch can actually use for installs and loading. The image supplied is SanDisk's official family gallery image from the Nintendo Switch microSD product page (character art varies by capacity in this licensed series). Lifetime limited warranty.
