The Switch needs a microSD card, and any standard one will work

The Nintendo Switch uses a microSD card to store games, screenshots, and video clips. The console comes with 32 GB of built-in storage, but that fills up quickly — a single large game takes 10 to 50 GB depending on the title. You can use any microSD card rated for the Switch; Nintendo does not lock you into a specific brand or seller.

The card slides into a slot on the back of the Switch, underneath the kickstand. You do not need any special tools or software. The Switch formats the card automatically when you insert it for the first time, and you can swap cards whenever you want without losing data on either one.

Speed matters less than capacity. The Switch reads games from the card slowly enough that even older, cheaper cards work fine. What matters is having enough space for the games you actually want to play at the same time.

Key Takeaways

  • Buy a microSD card with at least 128 GB of capacity; 256 GB or 512 GB gives you room to keep more games installed without deleting and re-downloading.
  • Any brand works — SanDisk, Samsung, Kingston, and store brands all function identically on the Switch.
  • Speed ratings (U3, V30, A1) do not affect game performance on the Switch, so the cheapest card in your target capacity is fine.
  • The Switch formats the card when you first insert it, so you do not need to do anything before using it.

How much storage you actually need

The 32 GB built-in storage holds about two large games or five to eight smaller ones. If you buy digital games instead of cartridges, you will run out of space within a few weeks. A microSD card lets you keep more games installed so you can play what you want without waiting for downloads.

A 128 GB card is the practical minimum. It gives you roughly 100 GB of usable space after the Switch formats it, which holds about three large games or a mix of smaller titles. If you play a wide variety of games or read a lot of indie titles, a 256 GB or 512 GB card is worth the small extra cost — you will not have to delete games to make room for new ones.

The Switch does not use the card for game performance. Whether you use a 128 GB card or a 512 GB card, games load at the same speed and play identically. The only difference is how many games you can keep installed at once.

Speed ratings and why they do not matter for the Switch

MicroSD cards come with speed ratings like U3, V30, and A1. These describe how fast the card reads and writes data. The Switch reads games slowly enough that even older, budget cards keep up without any slowdown. You will not notice a difference between a card rated V30 and one rated V90.

Speed ratings matter for cameras, drones, and other devices that write large amounts of data constantly. The Switch mostly reads games from the card; it does not write much. A cheap card and an expensive card perform identically in the Switch.

This means you can ignore speed ratings entirely and focus on capacity and price. The cheapest 128 GB or 256 GB microSD card you find will work just as well as a premium one.

Brand and where to buy

SanDisk, Samsung, Kingston, and Crucial all make microSD cards that work on the Switch. So do store brands from Target, Walmart, and Amazon. There is no performance difference between them. Pick whichever one is cheapest in the capacity you want.

Buy from a retailer you trust — Amazon, Best Buy, Walmart, or Target. Counterfeit microSD cards exist, especially on third-party marketplaces. A card from an official retailer is almost certainly real. If the price seems too low compared to other sellers, it probably is.

Prices vary by capacity and retailer. A 128 GB card typically costs $15 to $25. A 256 GB card runs $25 to $40. A 512 GB card costs $40 to $70. Prices drop during sales, so if you are not in a hurry, waiting for a holiday sale can save you money.

How to insert and format the card

The microSD card slot is on the back of the Switch, underneath the kickstand. Power off the console first. Gently push the card into the slot until you hear a click — it will spring back out slightly when it is seated correctly. Do not force it.

Power the Switch back on. The console will detect the card and ask if you want to format it. Select yes. Formatting takes a few seconds and erases anything already on the card, so only do this once when you first insert it. After that, the card is ready to use.

You can swap cards whenever you want. Games and saves stored on one card stay on that card. If you move a game to a different card, you will have to re-read it. For most people, one card is enough — you buy it once and leave it in the Switch.

Comparing microSD, microSDHC, and microSDXC

You will see three types listed: microSD, microSDHC, and microSDXC. These are just different capacity ranges. MicroSD cards hold up to 2 GB. MicroSDHC cards hold 4 GB to 32 GB. MicroSDXC cards hold 64 GB and up. The Switch works with all three, so buy whichever type has the capacity you want.

In practice, you will be buying a microSDXC card because they are the cheapest per gigabyte and come in the sizes that actually matter for the Switch — 128 GB and higher. The type name does not affect how it works in your console.

What to do if you run out of space

If your card fills up, you have two options: delete games you are not playing right now, or buy a larger card. Deleting a game frees up space when ready but requires re-downloading it later if you want to play again. Buying a new card is a one-time cost that gives you permanent extra space.

If you switch to a larger card, your old card still works — you can keep it as a backup or use it in another device. The Switch does not tie your games to a specific card. Your Nintendo account and save data stay on the console itself, not on the card, so you will not lose progress if you swap cards.

Frequently Asked Questions

Can I use a regular SD card instead of a microSD card?

No. The Switch only has a microSD slot, which is much smaller. A regular SD card will not fit. You need a microSD card specifically. Some retailers sell adapters that let you use a microSD card in an SD slot, but that does not help you — you still need the microSD card itself.

Do I lose my games if I remove the card?

The games stored on the card are no longer playable if you remove it, but they are not deleted. When you put the card back in, they work again when ready. Your save data and account information stay on the Switch console itself, so your progress is safe no matter what you do with the card.

Is a 128 GB card enough or should I get 256 GB?

A 128 GB card holds about three large games comfortably. If you play a lot of different games or read many indie titles, 256 GB gives you more breathing room and costs only $10 to $15 more. If you mostly play one or two games at a time, 128 GB is fine — you can always delete and re-read when you want to switch.

What happens if I buy a fake microSD card?

Counterfeit cards often fail after a few months or do not hold as much data as advertised. You might lose games or save data. Buy from an official retailer like Amazon, Best Buy, or Walmart to avoid counterfeits. If a price seems too good to be true, it probably is.

Can I use the same card in multiple Switch consoles?

Yes. The card works in any Switch. Your games are tied to your Nintendo account, not to a specific console, so you can move the card between devices. Save data stays on each console, so if you play the same game on two different Switches, each one has its own separate progress.
