Once a card is inserted, downloadable software normally goes there by default. Your game saves are different: Nintendo says save data stays in System Memory and cannot be copied to a microSD card. A card is therefore optional if you have enough internal space, but useful for a larger digital library.
The short answer
On the original Nintendo Switch family—Nintendo Switch, Nintendo Switch Lite and Nintendo Switch OLED—downloaded games, patches and downloadable content can occupy System Memory or a microSD card. The console’s built-in storage can also hold game saves. A microSD card expands the space available for software, screenshots and captured video; it does not expand the place where game progress is saved.

Nintendo’s support wording is explicit: “On Nintendo Switch, game save data is stored on the console’s System Memory.” It also says, “Game save data cannot be saved or copied to a microSD card.” This remains true whether you play from a game card or download the title.

What each storage location actually contains
System Memory
System Memory is the storage built into the console. It can contain downloaded games and their related software, but it is also the required location for save data. Your completed levels, settings, unlocked items and other progress remain there even when the playable software is stored on a microSD card.

microSD storage
A compatible microSD card is removable storage for downloadable software data. It can hold downloaded games, updates, downloadable content, screenshots and captured videos. Nintendo states that when a card is inserted, it becomes the default save location for downloadable software. In that sentence, “downloadable software” means the game data and related files—not the game’s saved progress.
Game-save data
Save data is tied to the console’s System Memory. Moving a game’s software files to a card does not move its saves, and deleting or archiving downloaded software does not remove those saves. If you reinstall the software later on the same console, the existing save data remains available unless it was separately deleted.
Is a microSD card necessary?
No. You can keep digital games in System Memory if the console has enough free space for the title and its updates. Nintendo does not prescribe one universal card size because storage needs depend on the number and type of games and other content you choose. Check the current eShop listing for a digital game’s required space before downloading; requirements can vary by game and can change when software is updated.

| Situation | Practical choice |
|---|---|
| There is enough free System Memory for the game and its updates. | Download to System Memory; a card is optional. |
| You want several large digital games installed at once. | Consider a compatible microSD card for software capacity. |
| You need to protect or move game progress. | A microSD card is not the solution; saves remain in System Memory. |
| You mainly use physical game cards and have little downloadable content. | Start without a card and add one only if free space becomes a problem. |
Compatible cards for Nintendo Switch, Switch Lite and Switch OLED
Nintendo lists three microSD categories for the original Switch family. The capacities below describe the supported card classes, not a promise about how many games will fit. Actual usable space and each game’s requirement vary.
| Card type | Capacity listed by Nintendo | Important condition |
|---|---|---|
| microSD | Up to 2 GB | Supported by the original Switch family. |
| microSDHC | 4 GB–32 GB | Supported by the original Switch family. |
| microSDXC | 64 GB–2 TB | A system update is required before using this category. |
Nintendo recommends a UHS-I-compatible card with a transfer speed of 60–95 MB/s. The support guidance says that higher transfer speed gives a better gameplay experience, but that range is compatibility guidance, not an independent ranking of retail cards. No single “fastest” card or universally correct capacity is established by Nintendo’s support information. Cards are sold separately.
If you decide you need more space, look for a product explicitly described as a Nintendo Switch-compatible microSDXC UHS-I card, then match its capacity to the games and media you expect to keep installed. Do not buy a card solely because it has a large number printed on the package; confirm that it follows the Switch compatibility guidance.
How downloads choose their location
With no microSD card inserted, downloadable software uses available System Memory. After you insert a compatible card, Nintendo says the card becomes the default location for downloadable software. This applies to new downloads; it does not mean that existing software is automatically relocated.

The console still uses System Memory for save data. A title can therefore have its game files on the card while its progress remains in the console. Updates and downloadable content are software files and may use the available software-storage location, although some update data can have movement restrictions.
Check space before buying or downloading
- Check the console’s free space: open System Settings and go to Data Management. Review the available System Memory and microSD capacity shown by the console.
- Check the title’s requirement: read the current eShop listing, or the storage information on the physical package where applicable. Nintendo advises checking this because requirements differ between games.
- Allow for updates and downloadable content: the listed download is not necessarily the only software that will be installed over the life of the game.
- Choose a storage location: use System Memory when it has sufficient room, or insert a compatible card when you need additional software capacity.
If the console reports that there is not enough room, Data Management lets you review installed software. You can archive or delete software that you are not using, or add a compatible microSD card. Archiving or deleting downloaded software leaves its save data unaffected.
Moving existing software between System Memory and a card
Nintendo’s current US instructions provide a migration command for eligible software data. It does not move everything on the console, so treat the menu as a selective tool rather than a way to transfer an entire installation, including saves.

- Select Data Management.
- Choose Move Data Between System / microSD Card.
- Select the direction—System Memory to microSD Card, or microSD Card to System Memory—then choose the eligible software data to move.
- Confirm the operation and wait for the console to finish before removing the card or powering down.
Game save data cannot be migrated by this process. Nintendo also identifies some update data as unable to move. The exact list of eligible items can depend on the software and the console’s current system software.

Nintendo regional support pages do not all describe the process identically. One regional article advises deleting or archiving software and redownloading it with the card inserted, while the current US instructions expose the move-data menu for eligible files. If the menu is unavailable or a particular title is not listed, use the supported fallback: preserve the save data, archive or delete the software, insert the compatible card, and redownload the title from your account.
What happens when you archive or delete a game?
Archiving removes the installed software files to free space while leaving the game’s save data on the console. Deleting downloaded software also does not erase the save data. You can redownload software associated with your account later, provided you have enough space on System Memory or the inserted microSD card.
Because saves are separate, moving or removing software is primarily a storage-management decision. It is not a method for transferring progress to another console or creating a card-based backup. Nintendo Switch Online save backups are a separate subject from download storage and should not be confused with microSD capacity.

Original Switch versus Switch 2
The card guidance above applies to Nintendo Switch, Switch Lite and Switch OLED. Do not apply it to Switch 2. Nintendo’s microSD FAQ says Switch 2 accepts only microSD Express cards. A standard microSD, microSDHC or microSDXC card selected under the original-Switch guidance is not the stated card type for Switch 2.

Before purchasing storage, identify the console model first. The correct decision is therefore:
- Original Switch, Switch Lite or Switch OLED: use a supported microSD, microSDHC or microSDXC card; microSDXC use requires a system update.
- Switch 2: use microSD Express, following Nintendo’s Switch 2 compatibility information.
Common decisions and pitfalls
“My game is on the card, so my save must be there too.”
It is not. Software files and save data are separate. The game can run from microSD while the save remains in System Memory.
“I need a card for every digital game.”
You do not. A card is needed only when the available System Memory is insufficient or you want to keep more software installed than the built-in storage allows.
“A 2 TB card means I can install 2 TB of games.”
The listed capacity is the card’s supported class, not a guarantee of usable space after formatting or of any particular game count. Use the eShop requirement for each title and the free-space reading in Data Management.
“Any fast card will work.”
Use Nintendo’s compatibility guidance: for the original Switch family, choose UHS-I compatibility and the recommended 60–95 MB/s transfer-speed range. Do not assume that a card designed for another device or a different console generation meets the requirement.
“Moving the game will move its progress.”
The move-data command concerns eligible software data. Saves remain in System Memory, and some update data cannot be moved.
A simple buying and storage rule
First check the game’s current storage requirement and the console’s free System Memory. If the title fits and you do not need a larger installed library, keep using internal storage. If repeated downloads, updates or captures leave too little room, add a card that matches your console generation and Nintendo’s compatibility specifications. Treat the card as expandable software storage—not as a save-data backup.
