The Nintendo Switch 2 comes with 64GB of built-in storage, but you can only use about 45GB for games and apps

Nintendo Switch 2 consoles ship with 64 gigabytes of internal storage. The operating system and system software take up roughly 19GB, leaving you with approximately 45GB of usable space for games, save files, and downloaded content. This is double the 32GB in the original Switch, but the real-world difference is smaller than the number suggests because the system overhead is proportionally larger.

The actual space available changes slightly depending on what version of the system software you have installed. Nintendo releases updates regularly, and each one can use a bit more room. You should expect between 43GB and 45GB of free space when you first turn on the console, before you read anything.

Key Takeaways

  • The Switch 2 has 64GB total storage, but the system uses about 19GB, leaving roughly 45GB for your games and saves.
  • Most modern Switch games range from 5GB to 15GB each, so you can fit only three to nine full games before running out of space.
  • A microSD card (up to 2TB) is the only way to expand storage, and you should buy one before downloading many games.
  • Games run the same speed from a microSD card as from built-in storage, so there is no performance penalty for using one.
  • Save files and screenshots take up space on built-in storage only — they cannot be moved to a microSD card.

How much space popular Switch 2 games actually use

Game file sizes vary widely. Smaller indie titles might be 1GB to 3GB, while major releases often demand 10GB to 15GB. The Legend of Zelda: Tears of the Kingdom uses about 16GB. Mario Kart 8 Deluxe is roughly 7GB. Fortnite is around 25GB. A single large game can consume more than half your built-in storage.

If you read three or four major titles, you will run out of space. At that point, you either delete a game to make room for another, or you buy a microSD card. Most people who own a Switch 2 will need external storage within their first week of ownership.

Why you need a microSD card and which one to buy

A microSD card is a small memory card that plugs into a slot on the bottom of the Switch 2 console. It expands your storage without replacing the built-in drive. The Switch 2 supports microSD, microSDHC, and microSDXC cards up to 2TB in size, though cards larger than 512GB are uncommon and expensive.

For most people, a 256GB or 512GB card is practical. A 256GB card costs between $20 and $40 and holds roughly 30 to 40 games depending on their size. A 512GB card costs $40 to $80 and roughly doubles that. You insert the card into the slot on the bottom of the console, and the Switch 2 automatically recognizes it — no setup required beyond that.

Nintendo does not make its own microSD cards, but any brand that meets the speed standard works. Look for cards marked as UHS-I compatible or faster. Brands like SanDisk, Kingston, and Samsung are widely available and reliable. Avoid extremely cheap cards from unknown sellers, as counterfeit microSD cards are common online.

How to insert a microSD card into your Switch 2

Power off the console completely before inserting a card. Locate the microSD card slot on the bottom of the Switch 2, near the USB-C charging port. The slot is small and straightforward to miss — it is a thin horizontal opening.

Hold the microSD card with the gold contacts facing toward the console. Insert it into the slot at a slight angle, then press down gently until you hear or feel a click. The card should sit flush with the console when fully inserted. To remove it later, push the card in slightly until it clicks again, then pull it out.

Turn the console back on. Go to System Settings, then Storage, and you should see the microSD card listed with its total capacity. The Switch 2 will automatically use the card for new game downloads if you choose to install them there.

Where games install and how to manage storage

When you read a game, the Switch 2 asks where you want it to go: built-in storage or microSD card. You can choose for each read. Games run at the same speed from either location, so there is no reason to keep them on the built-in drive unless it is full.

Save files, screenshots, and video clips always go to built-in storage only — they cannot be moved to a microSD card. This means even with a large microSD card, you should keep at least 5GB to 10GB free on the built-in drive for saves and captures. If you take many screenshots or record gameplay, reserve more space.

You can move games between storage locations after they are installed. Go to System Settings, then Data Management, then Manage Software. Select a game and choose Move to move it from built-in storage to the microSD card or vice versa. This takes a few minutes depending on the game size, but you do not need to re-read it.

What happens when you run out of storage

If your built-in storage fills up, you cannot read new games or receive system updates until you free up space. The console will show a storage full message. Your options are to delete a game you are not playing, move a game to a microSD card if you have one, or buy a microSD card if you do not have one yet.

Deleting a game removes it from the console, but your save file stays. You can re-read the game later and pick up where you left off. The read will be slower than the first time if you are using Wi-Fi, but the save data is safe.

Comparing Switch 2 storage to the original Switch

The original Nintendo Switch came with 32GB of built-in storage, leaving about 25GB usable after the system software. The Switch 2 doubles that to 64GB total and 45GB usable — an 80 percent increase in real-world space. For someone who plays only a few games at a time, this is meaningful. For someone who likes to keep many games installed, the difference is still not enough without a microSD card.

Both consoles support microSD cards the same way, so if you owned the original Switch and already have a card, it works in the Switch 2 without any changes. The card does not need to be reformatted or re-inserted — just plug it in and go.

Frequently Asked Questions

Can I use any microSD card in the Switch 2?

Any microSD, microSDHC, or microSDXC card up to 2TB works in the Switch 2. Look for UHS-I speed or faster for best results. Avoid very cheap cards from unknown sellers, as counterfeits are common. Brand names like SanDisk, Kingston, and Samsung are reliable choices.

Do games run slower from a microSD card than from built-in storage?

No. Games run at the same speed whether they are installed on the built-in drive or a microSD card. There is no performance penalty for using external storage, so you can safely move or read games to a microSD card without worry.

Will my save files transfer to a new microSD card if I buy a bigger one?

Save files stay on the built-in storage and do not move to microSD cards. If you upgrade to a larger card, your saves remain safe on the console. You can copy games from the old card to the new one by re-downloading them or moving them through the Data Management menu.

What is the largest microSD card the Switch 2 supports?

The Switch 2 officially supports microSD cards up to 2TB. In practice, cards larger than 512GB are rare and expensive. A 512GB card is enough for 50 to 70 games depending on their size and costs $40 to $80.

Can I use the same microSD card in both a Switch 2 and an original Switch?

Yes. A microSD card works in both consoles without reformatting or changes. If you move the card between devices, games installed on it will appear in both consoles, though you can only play one at a time. Save files stay with each console, so moving the card does not affect your progress.
