Insert and format the card, and the console can use it for downloaded games, updates, downloadable content, screenshots, and videos. Game save data remains in the console’s system memory, and Nintendo does not support USB hard drives for expanding game storage.
Using a Nintendo Switch 2? It requires a microSD Express card for downloadable software. A conventional Switch microSD card cannot store Switch 2 games.
Which storage works with each Nintendo console?
| Console | Compatible card | Maximum supported capacity |
|---|---|---|
| Nintendo Switch | microSD, microSDHC, or microSDXC | 2 TB |
| Nintendo Switch Lite | microSD, microSDHC, or microSDXC | 2 TB |
| Nintendo Switch OLED Model | microSD, microSDHC, or microSDXC | 2 TB |
| Nintendo Switch 2 | microSD Express only for software and media | 2 TB |
For the original Switch family, Nintendo lists microSD cards up to 2 GB, microSDHC cards from 4 GB to 32 GB, and microSDXC cards from 64 GB to 2 TB. A microSDXC card may require an internet-connected system update the first time it is used. See Nintendo’s microSD Card FAQ.
Switch 2 has separate requirements: only microSD Express cards can hold Switch 2 games, updates, DLC, screenshots, and videos. Ordinary microSD, microSDHC, and microSDXC cards from an original Switch are not suitable for Switch 2 game data. Nintendo’s compatibility details are in its Switch 2 compatibility FAQ and microSD Express FAQ.

What card should you buy for an original Switch?
Choose compatibility and reliability first
Buy a genuine microSDXC card from an established manufacturer and seller. Nintendo recommends UHS-I cards with transfer speeds of approximately 60–95 MB/s. A card advertising a much higher theoretical speed will not necessarily make games load proportionally faster on the original Switch.
A Nintendo-licensed card is optional. Licensed SanDisk cards offer recognizable branding and a warranty, while standard cards from reputable manufacturers can meet the same technical requirements. Counterfeit capacity, unreliable marketplace sellers, and card failure are greater risks than the absence of a Nintendo logo.
Choose capacity for your library
- 128 GB: Sensible for occasional digital purchases or a mostly physical collection.
- 256 GB: A balanced choice for many owners.
- 512 GB: Better for frequent digital purchases and sizeable DLC libraries.
- 1 TB: Useful for a large digital library, although value depends on how many games you buy physically.
Advertised capacity is decimal, so usable space is lower. Game sizes vary too much to promise a particular number of titles. Physical cartridges also may require downloads, and Nintendo says some physical releases require a microSD card.
Rank #2
- EXPAND YOUR STORAGE. Insert your card to add massive storage up to 1.5TB[1] to your Android smartphones and tablets, digital cameras, and laptops.
- SPACE FOR MORE. With expansive capacities up to 1.5TB[1], capture and store hours of Full HD video[4], movies, music, games, photos, and podcasts.
- MOVE FILES FAST. Use your card with the SANDISK QuickFlow microSD UHS-I Card USB-A Reader[6] to achieve up to 195MB/s[2] read speeds [128GB-1.5TB models] and offload your content fast.
- LOAD APPS IN A SNAP. Rated A1[3], the SANDISK Ultra microSD card is optimized for faster app launch and overall app performance.
- 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 and initialize a microSD card
- Turn the console completely off. Do not insert or remove the card while the system is running.
- Find the slot. On the original Switch it is beneath the kickstand; on Switch OLED it is beneath the wider adjustable stand; on Switch Lite it is under the rear cover area.
- Insert the card in the direction shown by the slot markings. Do not force it.
- Turn on the console. If prompted to format the card, accept only after backing up anything important on it. Formatting permanently erases its contents.
- If the card is microSDXC and the system requests an update, connect to the internet and complete the update.
- Open System Settings → Data Management and confirm that the card is recognized. Menu wording can vary with system software, so follow the labels shown on your console.
Downloaded purchases can generally be redownloaded with the Nintendo Account that bought them, but keep the original card until a replacement or reformat has been verified. Nintendo’s recognition troubleshooting is at this support page.

What can the card store?
| Can store | Cannot store |
|---|---|
| Downloaded games and applications | Game save data |
| Software updates | Save-data backups |
| Downloadable content | A plug-and-play game library for another Switch |
| Screenshots | Games launched from a USB hard drive or SSD |
| Captured gameplay videos |
Installing software on a card does not make its progress portable. Save data stays in the console’s system memory. Removing the card can stop software from launching until it is reinserted or the software is redownloaded, but it does not remove the save file from system memory.
Move software and free space
Use System Settings → Data Management. Depending on the title and whether a card is inserted, the console may offer options to move software between system memory and the microSD card, delete software, or archive it.
Rank #3
- 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.
Moving software
Select the software-management option, choose a title, and select the available move command. System-managed data does not always expose identical options, so use the commands presented for that title.
Archiving versus deleting
- Archive software: Removes downloaded program data to free space while retaining the HOME Menu icon and save data. Select the icon later to redownload.
- Delete software: Removes the downloaded program data. Save data is normally retained, but do not confuse this command with Delete Save Data, which is a separate and potentially irreversible action.
Archived or deleted purchases can generally be downloaded again from the HOME Menu or Nintendo eShop using the purchasing account.

You can also copy screenshots and videos to a computer through the Switch’s USB connection. This USB function is for media transfer, not for installing or running games from a drive. Nintendo’s instructions are at Screenshot and Video Management. Deleted media cannot be recovered through the console, so back it up before deleting or formatting.

Nintendo’s official card-to-card procedure is intended for the same console and specifically recommends Windows. You need the old card, the new compatible card, a microSD reader or adapter, and enough computer storage.
- Insert the new card into the Switch and format it if prompted, then turn the console off.
- Remove the new card and insert the old card. On a Windows PC, copy the old card’s entire contents to a folder on the computer.
- Safely eject the old card, insert the newly formatted card, and copy the complete folder structure to it. Do not copy only selected files, merge folders, or rename them.
- Insert the new card into the same Switch and confirm that software and media appear.
- Keep the old card untouched until the replacement has been tested.
Nintendo warns that this copy may not work correctly in environments other than Windows. Do not combine the contents of multiple cards later; Nintendo recommends using one card with one console. Follow the full procedure at Nintendo’s microSD transfer instructions.

Can the card be used in another Switch?
Not as a plug-and-play library. Nintendo states that software downloaded to a microSD card on one system will not be playable on a different system merely by moving the card. The new console may need to redownload the software under the purchasing Nintendo Account.
Save data requires a separate process:
- Use a nearby-console save transfer when moving a file directly between consoles. This moves the save rather than creating an independent duplicate, and Nintendo Switch Online is not required for that feature.
- Use Nintendo Switch Online Save Data Cloud where the user and game support it; not every title necessarily does.
- Use a full system transfer when replacing a console and the situation calls for one.
See Nintendo’s save-data transfer instructions.
Why a USB drive will not expand Switch storage
Nintendo currently does not support external USB hard drives, USB flash drives, or USB SSDs as expandable game storage on either the original Switch family or Switch 2. The USB-C port supports specified functions such as copying screenshots and videos to a computer; it is not a general-purpose external-drive interface for installing and running Switch games. Nintendo documents this limitation in the Data Management FAQ and the Switch 2 Data Management FAQ.
Troubleshoot an unrecognized card
- Check that the card type matches your console. Switch 2 requires microSD Express for game data.
- Power the console off completely, remove the card, and reinsert it carefully.
- Install the latest system update. A microSDXC card may not work until its required update is installed.
- Back up any readable screenshots, videos, or other content.
- Format the card in the console if necessary, remembering that formatting erases everything on it.
- Test another genuine, compatible card from a reliable seller.
- If several known-good cards fail, the card slot or console may need service.
Unusually cheap cards from marketplace sellers are especially worth treating with caution because counterfeit cards can report false capacities or fail under load.
Switch 2: the important difference
Do not buy a conventional UHS-I microSDXC card for Switch 2 game storage. Switch 2 accepts microSD Express cards up to 2 TB; its save data still remains in system memory, and external USB drives remain unsupported. Nintendo says an Express card’s speed on an original Switch is equivalent to that of a conventional microSD card, so an expensive Switch 2 Express card is not a worthwhile upgrade for an original Switch solely because of its headline speed.
