Its 256 GB of internal UFS storage is partly reserved for system use. Older, ordinary microSD, microSDHC and microSDXC cards from the original Switch cannot store or run Switch 2 games, although they can import Switch screenshots and videos.
Downloaded games, updates, downloadable content, screenshots and captured videos can use a microSD Express card. Game save data stays in the console’s system memory. Nintendo requires an internet system update the first time you use a microSD Express card.

What storage does Nintendo Switch 2 support?
Switch 2 has 256 GB of internal UFS storage, but Nintendo reserves part of that capacity for system use. The usable amount for games and captures is therefore lower than 256 GB; Nintendo does not state a universal usable figure in the cited technical specifications.

For expansion, the console supports microSD Express cards up to 2 TB. Nintendo’s support guidance says any card that meets the microSD Express standard and stays within the 2 TB limit can be used. A card being labeled only “microSDXC,” even at a large capacity, does not establish compatibility.
#1 Best Overall
- 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.
microSD Express is a storage standard designed for faster access than conventional microSD cards. Nintendo identifies that faster access as necessary for smooth game operation on Switch 2. No independent speed comparison or ranking is established here, so a more expensive compatible card should not be assumed to improve frame rates or gameplay performance.
Which card types work, and which do not?
| Card type | Can it store or run Switch 2 games? | Other supported use |
|---|---|---|
| microSD Express | Yes, up to 2 TB, provided it meets the microSD Express standard | Downloaded software, updates, DLC, screenshots and captured videos |
| Ordinary microSD | No | Can import screenshots and videos made on an original Nintendo Switch |
| microSDHC | No | Can import screenshots and videos made on an original Nintendo Switch |
| microSDXC | Not by the label alone; it must explicitly meet the microSD Express standard | Legacy cards can import screenshots and videos, but cannot hold Switch 2 game data |
| External USB hard drive | No | Nintendo’s Data Management FAQ says USB hard drives are not currently supported |
This distinction matters when reusing a card from the original Switch. The card is not completely useless, but Switch 2 cannot use a conventional card as a game-storage replacement. It can import compatible screenshots and videos from that card.
What can be saved to a microSD Express card?
Downloaded software, updates and DLC
Nintendo says downloaded software becomes the default save location for a microSD Express card once one is inserted. Software update data and downloadable content can also be stored there. This is the card’s principal purpose: expanding space for digitally delivered software without replacing the console’s internal memory.
Game save data stays in system memory
Save data is separate from the installed game. Nintendo states that game save data cannot be copied to a microSD Express card. Removing the card, changing cards or replacing a full card therefore does not move your progress to removable storage.
Nintendo’s data-management guidance identifies Nintendo Switch Online cloud backup as an option for supported titles. Cloud backup availability depends on the game and service support; it is not the same as copying saves to the microSD Express card.

Screenshots and captured video
Screenshots and captured videos can be moved between system memory and the microSD Express card. This makes the card useful for managing capture space even though it cannot hold game saves.
How to use a microSD Express card for the first time
- Check the marking before buying. Confirm that the product explicitly says “microSD Express.” Do not choose solely by capacity, a microSDXC label or a claim that it worked in the original Switch.
- Stay within the supported capacity. Switch 2 supports cards up to 2 TB. Cards above that limit are outside Nintendo’s stated compatibility guidance.
- Insert the card into the console. Follow the console’s on-screen instructions after insertion. Nintendo requires an internet system update the first time a microSD Express card is used.
- Allow the update to finish before managing software. The first-use update is a requirement from Nintendo, not an optional performance tweak.
- Check where content is stored. Downloaded software uses the inserted card as its default location. Save data remains in system memory, while screenshots and videos can be moved between locations.
Nintendo’s published guidance does not establish a universal menu path, formatting procedure or recovery workflow for every system-software version. Use the labels shown by the console rather than relying on instructions written for the original Switch.
How much capacity should you buy?
There is no capacity that Nintendo identifies as best for every owner. Select a card by comparing the size of your planned digital library and capture collection with the card’s capacity, then check the current price and availability in your region.
- Mostly physical games: internal storage may cover more of your downloaded updates and DLC, but the card can still provide room for digital purchases and captures.
- Mostly digital games: prioritize enough capacity for the library you expect to keep installed at the same time. Nintendo does not publish a fixed number of games per capacity, and game sizes vary.
- Frequent screenshot or video capture: include capture storage in your estimate because those files can be moved to the card.
- Long-term planning: compare one larger card with the cost of replacing a smaller card later. A larger card does not move save data off the console.
Do not treat the internal “256 GB” figure as 256 GB available for games. Some space is reserved for system use, and Nintendo does not provide a single usable-capacity number that applies to every console state.
Can you use multiple microSD Express cards?
Nintendo recommends using one microSD Express card. If it fills up, Nintendo says you can copy all data to a larger card. However, downloadable software stored across multiple microSD Express cards cannot later be combined into one card.

Note that actual usable storage may be slightly less due to system formatting and a portion reserved for card management functions, which is a standard industry practice to ensure optimal performance and reliability.
That limitation affects planning. Rotating cards can leave your library divided, requiring you to keep track of which card contains each installation. A single card also gives you one place to manage downloaded software and capture files. Regardless of how many cards you use, game saves remain in system memory rather than following the software.
Moving to a larger card
- Obtain a larger card that meets the microSD Express standard and remains within the 2 TB limit.
- Copy all data from the existing card to the larger card using Nintendo’s supported data-management process and the instructions displayed by your console.
- Keep the original card until you have confirmed that the copied software and captures are recognized.
The important condition is that Nintendo describes copying all data to a larger card; it does not describe merging separate cards into one library.
Nintendo-listed microSD Express examples
Nintendo’s Japanese product page lists licensed examples. These are examples, not a ranking and not the only compatible products. Nintendo’s compatibility rule remains the microSD Express standard plus the 2 TB maximum.
| Manufacturer and capacity | Nintendo-listed release date | What the listing establishes |
|---|---|---|
| SanDisk 256 GB | June 5, 2025 | A licensed example listed for Switch 2 |
| Samsung 256 GB | June 5, 2025 | A licensed example listed for Switch 2 |
| SanDisk 512 GB | October 1, 2026 | A later licensed example listed for Switch 2 |
Those dates describe Nintendo’s product-page release information, not current stock or a guaranteed price. Availability, pricing, warranty terms, endurance and comparative reliability can vary by country and retailer and are not established by Nintendo’s compatibility statement.
How to compare two compatible cards
Once both products explicitly meet the microSD Express standard, use practical criteria rather than assuming a brand or capacity is automatically superior.

Buying a large conventional microSDXC card
Symptom: the card has a high capacity but is not recognized as suitable for Switch 2 game storage.
Fix: check for the explicit microSD Express designation. Capacity alone cannot substitute for the required standard.
Expecting saves to appear on the card
Symptom: installed software is on the card, but saved progress remains on the console.

Assuming an old Switch card can run Switch 2 games
Symptom: a card that worked in the original Switch cannot be selected for Switch 2 game storage.
Fix: use the old card only for importing compatible screenshots and videos. Buy a microSD Express card for Switch 2 software.
Using several cards and later trying to merge them
Symptom: software is divided across cards and cannot be consolidated automatically.
Recommended Free Tools
Fix: Nintendo recommends one card. If you need more room, copy the data to a larger single card rather than expecting multiple cards to merge.
Skipping the first-use update
Symptom: a new card does not work immediately after insertion.
Fix: connect the console to the internet and complete the required system update for first-time microSD Express use.
What the card does not change
- It does not increase the console’s internal 256 GB capacity; it adds separate expansion storage.
- It does not relocate game save data from system memory.
- It does not guarantee higher frame rates, better graphics or faster gameplay than another compatible microSD Express card.
- It does not make an ordinary legacy microSD, microSDHC or microSDXC card suitable for Switch 2 game storage.
- It does not make an external USB hard drive a supported storage option under Nintendo’s current FAQ guidance.
Bottom line for choosing a card
Buy a microSD Express card, not a conventional microSD card, and keep the capacity at 2 TB or below. Choose the size by the digital games, updates, DLC and captures you expect to keep installed, while remembering that some of Switch 2’s 256 GB internal storage is reserved and that saves remain in system memory. Nintendo recommends one card and supports copying its data to a larger card later, but it does not support combining software spread across several cards.
