Best Switch SD card for game storage?
Why Your Nintendo Switch Needs an SD Card for Game Storage
The Nintendo Switch is a fantastic portable console, but its Achilles’ heel for many gamers is its limited internal storage. With only 32GB (or 64GB for the OLED model), a significant portion of which is reserved for the system, it doesn’t take long for digital game downloads, updates, and DLC to fill up your available space. This is where a high-quality microSD card becomes an indispensable accessory, transforming your gaming experience by providing ample room for all your favorite titles.
Without an SD card, you’ll constantly be forced to delete games to make space for new ones, a frustrating and time-consuming process. Investing in the right SD card ensures you can keep a vast library of games ready to play whenever you are.

Understanding SD Card Specifications for Switch Gaming
Choosing an SD card isn’t just about picking the largest capacity; speed and compatibility are equally crucial for optimal performance on your Switch. Here’s what you need to look for:
Capacity: How Much Storage Do You Need?
- 256GB: A good starting point for casual gamers or those who mostly buy physical cartridges.
- 512GB: The sweet spot for most digital-heavy gamers, offering significant space for numerous AAA titles and indie games.
- 1TB: For the ultimate digital collector, ensuring you virtually never run out of space, even with massive game libraries.
Remember that some games, like The Legend of Zelda: Tears of the Kingdom, can exceed 18GB, and many others hover around the 10-15GB mark. Factor in updates and DLC, and storage fills up fast.
Speed: A1 vs. A2 and UHS-I
The Nintendo Switch supports UHS-I microSD cards, with theoretical read speeds up to 104 MB/s. While faster cards exist, the Switch itself can’t fully utilize UHS-II or UHS-III speeds, so stick to UHS-I for the best value.
- UHS Speed Class (U1, U3): Look for U1 (10MB/s minimum write speed) or U3 (30MB/s minimum write speed). U3 is generally preferred for smoother performance, especially with larger games.
- Application Performance Class (A1, A2): This rating is crucial for gaming.
- A1 cards offer minimum random read speeds of 1500 IOPS and random write speeds of 500 IOPS.
- A2 cards provide significantly better performance, with minimum random read speeds of 4000 IOPS and random write speeds of 2000 IOPS. While the Switch may not fully leverage all A2 benefits, these cards generally offer better overall responsiveness for loading games and in-game assets.
For the best experience, aim for a U3 A2 rated card.
