What to Look for in a Switch microSD Card

Before diving into our recommendations, let's cover the key specs that matter for Nintendo Switch homebrew:

Speed Ratings Explained

  • Read Speed: How fast data can be read from the card. Look for 100MB/s or higher.
  • Write Speed: Important for installing games. 60MB/s+ is ideal.
  • UHS-I: The Switch only supports UHS-I, so don't overpay for UHS-II cards.
  • Application Performance Class (A1/A2): A2 is better for running apps directly from the card.

How Much Storage Do You Need?

For homebrew users, we recommend at least 256GB. Here's why:

  • 128GB: Bare minimum, fills up quickly
  • 256GB: Sweet spot for most users (our recommendation)

Tips for Buying microSD Cards

⚠️ Beware of Counterfeits!

Always buy from reputable sellers (Amazon direct, official brand stores). Fake cards are common and can corrupt your data.

  1. Buy from authorized retailers: Amazon (sold by Amazon), Best Buy, official brand websites
  2. Check reviews: Look for recent reviews mentioning authenticity
  3. Test your card: Use H2testw (Windows) or F3 (Mac/Linux) to verify capacity
  4. Format correctly: Use FAT32 for cards over 64GB (the Switch requires this for some homebrew)

Frequently Asked Questions

Does the Nintendo Switch support 1TB microSD cards?

Yes, the Nintendo Switch officially supports microSD cards up to 2TB. However, 512GB is usually more than enough for most users and offers better value.

Do I need a fast microSD card for the Switch?

While the Switch can use slower cards, faster cards (100MB/s+ read speed) will significantly improve game loading times and installation speeds. We recommend UHS-I cards with at least 100MB/s read speed.

Should I format my microSD card before using it?

New cards usually work out of the box, but for homebrew use, you may need to format to FAT32 for cards larger than 64GB. The Switch's built-in formatter can also be used.

How do I know if a microSD card is fake?

Buy from authorized retailers, check for suspiciously low prices, and test the card with verification software like H2testw or F3. Fake cards often show the wrong capacity and corrupt data.

Conclusion

For most Nintendo Switch homebrew users, we recommend the Samsung EVO Select 256GB as the best overall choice. It offers the perfect balance of speed, reliability, and capacity. If you're on a tighter budget, the SanDisk Ultra 256GB is an excellent alternative.
