The Switch 2 comes with 64GB of built-in storage, but you'll use less than half of that for actual games

The Nintendo Switch 2 has 64GB of internal storage. However, the system itself takes up about 27GB, which means you have roughly 37GB available for games, screenshots, and video clips when you first turn it on. That sounds like enough until you start downloading games — most modern titles take 10GB to 50GB each, so you'll fill that space quickly.

The real solution is a microSD card. The Switch 2 accepts microSD, microSDHC, and microSDXC cards up to 2TB in size. In practice, you'll want at least a 256GB or 512GB card, which cost between $20 and $50. A 1TB card runs $60 to $100 depending on the brand and speed rating. This is not optional if you plan to own more than two or three games.

Key Takeaways

  • The Switch 2 has 64GB built-in, but the system uses about 27GB, leaving you roughly 37GB for games and saves.
  • Most modern Switch games range from 10GB to 50GB each, so the built-in storage fills up after downloading just a few titles.
  • You can expand storage with a microSD card up to 2TB, and a 256GB or 512GB card is the practical minimum for regular gaming.
  • microSD cards are cheap enough that skipping one is a false economy — a 512GB card costs less than a single full-price game.

Why the built-in storage runs out so fast

Game sizes have grown significantly. A Nintendo Switch game from 2017 might have been 5GB or 10GB. Current titles regularly hit 30GB to 50GB. The Legend of Zelda: Tears of the Kingdom is 16.3GB. Doom Eternal is 27GB. If you download four or five games, you've used most of your available space.

The system also reserves space for game updates. When a game receives a patch, it needs temporary room to download and install the update before replacing the old version. Without enough free space, the update fails. Nintendo recommends keeping at least 10GB to 15GB free at all times for this reason.

Screenshots and video clips also take up room. The Switch 2 can record up to 30 minutes of gameplay video, and each minute of video takes roughly 200MB to 300MB depending on the game. If you record regularly, this adds up.

Choosing the right microSD card size

A 256GB card holds roughly 200 games of average size (assuming 10GB to 15GB per game). A 512GB card holds roughly 400 games. A 1TB card holds roughly 800 games. Most people never own that many games, so 256GB or 512GB is the practical choice.

Speed matters less than capacity. The Switch 2 reads from microSD cards at a fixed speed, so a faster card won't load games any quicker than a slower one. Any card labeled "microSDXC" will work fine. Brands like SanDisk, Kingston, and Samsung are reliable and widely available. Avoid extremely cheap cards from unknown sellers — they often fail or have less actual storage than advertised.

Check the card's speed class rating if you plan to record video. A card rated "U3" or "V30" is fast enough for video recording without stuttering. Most modern cards meet this standard.

How to install a microSD card in your Switch 2

The microSD card slot is on the bottom of the Switch 2, behind the kickstand. Power off the console completely before inserting or removing a card — doing it while the system is on can corrupt your data.

Open the kickstand and look for a small slot on the bottom edge. Insert the microSD card with the gold contacts facing into the console. Push gently until you hear a click. The card should sit flush with the console when fully inserted. To remove it, push the card in slightly until it clicks and pops out.

When you insert a new card, the Switch 2 will format it automatically. This erases anything already on the card, so make sure it's blank or that you've backed up any files you need. The formatting takes a few minutes.

Managing storage when your card gets full

The Switch 2 lets you see exactly how much space each game uses. Go to System Settings, then Storage, then Manage Software. You'll see a list of every installed game with its size. Delete games you're not playing to free up room.

You can also archive a game instead of deleting it. Archiving removes the game files but keeps your save data, so you can reinstall the game later without losing progress. This is useful for games you might return to but don't want to keep installed.

If you're running low on space and don't want to delete anything, the only solution is a larger microSD card. You can swap cards at any time — just power off, remove the old card, insert the new one, and the console will recognize it immediately. Your save data stays on the console's internal storage, not on the card, so switching cards won't affect your progress.

Can you use multiple microSD cards?

You can only use one microSD card at a time. The Switch 2 has a single card slot, and you can't use two cards simultaneously. However, you can swap cards whenever you want. Some people keep multiple cards and rotate them depending on which games they want to play, though this is inconvenient and most people just buy one large card instead.

If you do swap cards, the console will recognize whichever card is inserted. Games installed on one card won't appear when you insert a different card, so you'll need to reinstall them or keep track of which games are on which card.

Storage comparison: Switch 2 vs. the original Switch

The original Nintendo Switch came with 32GB of storage. The Switch 2 doubles that to 64GB. However, game sizes have also grown significantly since the Switch launched in 2017, so the extra 32GB doesn't go as far as it sounds. Both consoles require a microSD card for practical use if you own more than a handful of games.

The Switch 2 supports larger microSD cards than the original Switch. The original Switch maxed out at 2TB in theory but had practical limits with older cards. The Switch 2 officially supports up to 2TB with no practical limitations, so you have more flexibility if you want to buy a very large card.

Frequently Asked Questions

Do I have to buy a microSD card right away?

No, but you'll need one within a few weeks if you download more than two or three games. You can start with the built-in storage and add a card later without any problem. Your existing games and saves will stay on the console.

What happens if my microSD card fails?

Your save data is stored on the console itself, not on the card, so you won't lose progress. You'll lose any games installed on that card, but you can redownload them to a new card. This is why buying a reliable brand matters — a failed card is inconvenient but not catastrophic.

Can I use a microSD card from my old Switch on the Switch 2?

Yes. The Switch 2 is backward compatible with microSD cards from the original Switch. Just insert your old card and the console will recognize it. You don't need to reformat it or do anything special.

Is a 256GB card enough or should I get 512GB?

A 256GB card is enough for 15 to 20 large games plus screenshots and video. If you own more games than that or plan to keep a large library installed, 512GB is worth the extra $15 to $20. Most people are fine with 256GB.

Do faster microSD cards make games load quicker?

No. The Switch 2 reads from microSD cards at a fixed speed regardless of the card's rated speed. A faster card won't improve load times. Buy based on capacity and reliability, not speed rating.
