Switch storage full? Best SD card for digital games?
Is Your Nintendo Switch Storage Bursting at the Seams?
For many Nintendo Switch owners, the joy of a growing digital game library eventually gives way to a familiar frustration: the dreaded “storage full” message. With many AAA titles easily exceeding 10GB, and the Switch’s internal 32GB (or 64GB for OLED models) filling up rapidly, an expandable storage solution isn’t just a luxury – it’s a necessity for any serious gamer. Fortunately, the Switch supports microSD cards, making storage expansion a straightforward process.
But with a dizzying array of options on the market, how do you choose the best SD card for your digital games? This guide will walk you through what to look for and recommend top picks to ensure your gaming adventures are never interrupted by a lack of space.

Why You Need a MicroSD Card for Your Switch
While the Nintendo Switch’s internal storage is fine for a few smaller titles or physical game saves, it’s simply not enough for a substantial digital library. Games like The Legend of Zelda: Tears of the Kingdom, Pokémon Scarlet/Violet, or Mortal Kombat 11 can each take up significant chunks of space. Downloading multiple large titles quickly exhausts the internal memory, forcing you to constantly delete and re-download games – a time-consuming and frustrating cycle.
A microSD card provides seamless, high-capacity storage that integrates perfectly with your Switch. Once inserted, the console treats it as an extension of its own memory, allowing you to download new games directly to the card without a second thought. This means more games, less hassle, and uninterrupted gaming.
Key Factors When Choosing a Switch MicroSD Card
Not all microSD cards are created equal, especially when it comes to gaming. Here’s what you should prioritize:
1. Capacity: How Much Space Do You Need?
- 128GB: A good starting point for casual gamers or those who mostly buy physical games.
- 256GB: The sweet spot for most gamers, offering ample space for a diverse digital library without breaking the bank.
- 512GB: Excellent for avid digital collectors. You’ll likely never worry about space again.
- 1TB: The ultimate choice for serious digital hoovers. While more expensive, it offers maximum peace of mind.
Remember, it’s always better to go a little larger than you think you need. Games only get bigger, and your library will grow.
2. Speed: Read and Write Performance
This is crucial for smooth gaming. Look for:
- UHS-I (Ultra High Speed Phase I): The Switch supports UHS-I cards, with a theoretical maximum speed of 104 MB/s. Don’t bother with expensive UHS-II or UHS-III cards; the Switch can’t utilize their higher speeds.
- Speed Class (U1 or U3): U3 cards offer a minimum sequential write speed of 30 MB/s, while U1 offers 10 MB/s. For games, U3 is preferable for faster load times and smoother performance, though U1 is often sufficient.
- Application Performance Class (A1 or A2): This rating indicates how well a card handles random read/write operations, which are vital for game loading and saving. An A2 rating is ideal for gaming as it provides better random performance than A1, leading to quicker game launches and reduced loading screens.
In summary, aim for a UHS-I U3 A2 rated microSD card for the best performance on your Switch.

3. Brand Reliability
Stick with reputable brands like SanDisk, Samsung, or Lexar. These brands are known for their quality, durability, and robust warranty support. Counterfeit cards are a real problem, so always buy from trusted retailers.

To manage your data:
