If you're looking for the best microSD card for Nintendo Switch, the SanDisk Ultra Micro SDXC 256GB is our top recommendation. It offers a reliable balance of speed, capacity, and price, making it ideal for storing games, updates, and screenshots.
Running out of space on your Nintendo Switch is a common problem. Between game updates, save data, and eShop downloads, the console's internal storage fills up quickly. Adding a microSD card is the easiest solution.
Why You Need a MicroSD Card for Your Nintendo Switch
The Nintendo Switch comes with only 32GB of internal storage, and a portion is reserved for system files. After a few game downloads, you'll likely see a "storage full" message. A microSD card expands your storage, letting you keep more games installed and ready to play.

Not all microSD cards are created equal, though. The Switch requires a card with at least UHS-I speed and a Class 10 or U1 rating for smooth performance. Using a slower card can lead to longer load times and potential game hiccups.

1. SanDisk Ultra Micro SDXC 256GB – Best Overall
The SanDisk Ultra Micro SDXC 256GB is our top choice for most Switch owners. It offers ample space for a large game library and delivers read speeds up to 150 MB/s, which is more than enough for the Switch's requirements.

It's also A1-rated for app performance, meaning it can handle the random read/write operations that games often require. The card is widely available and often priced competitively, making it a great value.
2. Samsung EVO Select 256GB – Fast and Reliable
Samsung's EVO Select is another excellent option. With U3 and Class 10 ratings, it's designed for fast data transfers and can handle large files with ease. It's a bit faster than the SanDisk Ultra in write speeds, which is useful if you frequently transfer screenshots or videos to your PC.
The EVO Select is also backed by a solid warranty and has a proven track record for reliability.
3. SanDisk Extreme 128GB – For Performance Seekers
If you prioritize speed, the SanDisk Extreme is a step up. It offers read speeds up to 160 MB/s and write speeds up to 90 MB/s, along with a V30 rating for sustained video recording. While the Switch won't fully utilize these speeds, it ensures future-proofing and smooth performance.
This card is ideal if you also plan to use it in other devices like a camera or drone.
4. Kingston Canvas Select Plus 128GB – Budget-Friendly
For budget-conscious gamers, the Kingston Canvas Select Plus is a solid choice. It provides read speeds up to 100 MB/s and comes with a Class 10, U1 rating, meeting the Switch's requirements. It may not be the fastest, but it gets the job done for storing and playing games.
If you mainly play physical games and only need extra space for updates and a few digital titles, this card offers great value.
5. Lexar Play 256GB – Gaming-Optimized
The Lexar Play is specifically designed for gaming devices, with an A2 rating for high random read/write performance. This means faster game load times and smoother multitasking. It offers read speeds up to 150 MB/s and comes in capacities up to 1TB.
It's a bit pricier than the SanDisk Ultra, but the A2 rating can make a noticeable difference in game performance.

What to Look for in a MicroSD Card for Nintendo Switch
When choosing a microSD card, keep these key factors in mind:
- Capacity: 128GB is a good starting point, but 256GB or higher is better if you download many games.

- Brand: Stick with reputable brands like SanDisk, Samsung, Kingston, or Lexar for reliability.

- Warranty: A long warranty (e.g., 10 years) is a sign of quality.
