How to Expand Nintendo Switch Storage with a microSD Card

Expand storage on Nintendo Switch, Switch Lite, or OLED with a supported microSD card. Learn what to buy, what moves to the card, and how to upgrade safely.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

For Nintendo Switch, Switch Lite, and Switch OLED, add storage by inserting a microSD card. The practical choice is a microSDXC UHS-I card: Nintendo supports microSDXC capacities from 64 GB to 2 TB and recommends UHS-I cards with transfer speeds of 60–95 MB/sec. A system update is required to use microSDXC. These recommendations do not apply to Nintendo Switch 2, which requires microSD Express for game storage.

Which microSD card should you buy?

Choose a card labeled microSDXC and UHS-I. Check the package or card specifications before buying; a full-size SD or miniSD card will not fit the Switch’s microSD slot. Cards are sold separately.

Nintendo’s supported types and capacity ranges are:

Card type Capacity listed by Nintendo Notes
microSD Up to 2 GB Supported.
microSDHC 4–32 GB Supported.
microSDXC 64 GB–2 TB Supported; a system update is required.

Nintendo recommends UHS-I compatibility and gives 60–95 MB/sec as its high-speed guideline. It says a higher transfer speed can improve the gameplay experience, but the card’s advertised peak speed is not a promise of the speed the console will achieve. Capacity is a matter of how much downloaded software and captured media you expect to keep; Nintendo’s specifications do not establish one best capacity or value pick. See Nintendo’s microSD Card FAQ for compatibility details.

#1 Best Overall

  • Compatible with Nintendo-Switch (NOT Nintendo-Switch 2)
  • Incredible speeds in a microSD card officially licensed for the Nintendo Switch, Nintendo OLED, and Nintendo Switch Lite systems

What does a microSD card store?

With a card inserted, downloadable software is saved to it by default. A microSD card can also store software update data, downloadable content (DLC), screenshots, and captured video.

Game save data is different: it remains in system memory and cannot be copied or saved to a microSD card. Adding a card expands room for software and media, not game saves. Nintendo states this in its microSD Card FAQ.

  • EASY CONTENT MANAGEMENT. Easily back up, organize, and transfer your photos and videos with the SANDISK Memory Zone desktop or Android mobile app[5].

How to install a new card

  1. Turn off the console before inserting the card.
  2. Insert the microSD card into the console’s microSD card slot, following the console’s orientation markings.
  3. Turn the console on. If the card is microSDXC, install the required system update if prompted.

Once the card is recognized, new downloadable software uses it as the default storage location. Existing software data in system memory does not simply move to the card. If you need to free system memory, Nintendo’s guidance is to delete the software and redownload it with the card inserted; downloadable software can be downloaded again from the account that purchased it. Details are in Nintendo’s microSD Card FAQ.

How to upgrade from one card to a larger card

If you want to keep installed content while replacing a card, copy the old card’s contents to the new card using a computer. You will need compatible cards and either a computer SD slot or a commercially available microSD card reader. This reader is for the transfer process; it is not needed for ordinary installation in the console.

Samsung microSD Express Card – 256GB for Nintendo Switch™ 2
  • Nintendo Switch 2 uses a new standard of expandable memory card called microSD Express (sold separately). This kind of memory card is needed for faster access speeds and to ensure games will run smoothly.
  • Please note: Nintendo Switch 2 is only compatible with microSD Express cards. If the microSD cards you have used for Nintendo Switch do not support microSD Express standards, you cannot use them with Nintendo Switch 2.
  1. Turn off the console and remove the original card.
  2. Connect the original card to a computer and copy its entire folder to the computer. Do not erase or alter the original card.
  3. Connect the new card and copy the entire folder onto it.
  4. Safely eject the new card, insert it into the console, and check that the console recognizes the card and the content you intended to preserve.
  5. Keep the original card unchanged until you have confirmed the new card works.

Follow Nintendo’s full transfer instructions for the required folder-copy process. Nintendo recommends using one card with the console: software stored on separate cards cannot later be combined into one, so rotating cards is not a seamless way to build a single library.

Does this advice apply to Nintendo Switch 2?

No. Nintendo Switch 2 uses microSD Express for game storage. An Express card used in an original Nintendo Switch reads and writes at ordinary microSD speeds, and the original Switch’s microSDXC recommendation does not add game storage to Switch 2. Check Nintendo’s microSD Card and microSD Express Card Compatibility guidance for the distinction.
