The Switch 2 Has 256 GB of Storage. These Games Don't Care.
Here is what happens when you buy a Switch 2 and download the four most popular games on the platform right now:
Mario Kart World — 23.4 GB. The best-selling Switch 2 game with over 15 million copies sold. Everyone buys this.
Fortnite — 49.4 GB. Free to play, installed on virtually every gaming device that supports it.
Elden Ring: Tarnished Edition — 50 GB. One of the most acclaimed RPGs of the decade, now portable for the first time.
Final Fantasy VII Rebirth — 91.8 GB. The blockbuster that Square Enix rebuilt from the ground up for Switch 2.
Total: 214.6 GB. The Switch 2 ships with 256 GB of internal storage, roughly 220 GB of which is usable after the operating system takes its share. Four games. Your brand-new console is full.
And you have not downloaded a single update, a single piece of DLC, saved a single screenshot, or installed any of the other titles sitting in the eShop that you bought this console to play. You have not touched NBA 2K26 (71 GB), EA Sports FC 26 (75 GB), Cyberpunk 2077 (61 GB), or WWE 2K26 (86 GB). Every one of those is waiting behind a storage wall.
The Switch 2 is a generational leap in performance. It is also shipping with a storage capacity that its own game library outgrew before the console was three months old.
Why Switch 2 Storage Is a Different Problem Than You Think
The original Switch trained everyone to ignore storage. Most Switch 1 games were small — 5 to 15 GB for a typical title. Breath of the Wild was 14.4 GB. Animal Crossing was 7.1 GB. You could install a dozen games on a cheap 128 GB microSD card and never think about it again. The Switch 2 does not work that way. Third-party ports are arriving with asset quality close to their PS5 and Xbox counterparts — not the heavily compressed, resolution-reduced versions that fit on the original Switch. File sizes have multiplied by factors of four to ten.
The biggest Switch 2 games are already approaching 100 GB each. Final Fantasy VII Rebirth sits at 91.8 GB. WWE 2K26 is 86 GB. EA Sports FC 26 is 74.8 GB. NBA 2K26 is 71.2 GB. These are not outliers — they are mainstream, mass-market titles that millions of people will download. And game sizes tend to grow over a console generation, not shrink. The titles releasing in year three and four of the Switch 2's life will be larger than anything available today.
Nintendo's own first-party games are no longer trivially small. Mario Kart World is 23.4 GB — modest by third-party standards, but larger than almost every first-party Switch 1 title. As Nintendo's own studios build for the Switch 2's expanded capabilities — higher-resolution textures, more complex physics, larger worlds — their file sizes will climb further. The days of fitting a dozen Nintendo games in 50 GB are over.
You cannot use your old Switch microSD card. The Switch 2 uses a microSD Express slot — a different physical and electrical standard from the original Switch's UHS-I slot. Your existing microSD card does not fit. Every Switch 2 owner who wants expanded storage needs a new card, period. This is not an upgrade — it is a fresh purchase.
The Suitcase That Fits Four Shirts
Imagine buying an expensive new suitcase for a two-week holiday. It is beautifully designed. Premium materials. Rolls perfectly through an airport. You get home, start packing, and discover that it fits exactly four shirts. Not four outfits — four individual shirts. No trousers, no shoes, no toiletries. Just four shirts and a zipper that will not close if you fold one wrong.
You would not throw the suitcase away — it is genuinely excellent at what it does. But you would immediately buy a packing cube or a second bag, because four shirts is not a packing strategy. It is a constraint you solve before you leave the house, not at the airport gate.
That is the Switch 2's 256 GB of internal storage. The console is exceptional. The storage allocation is not. And unlike a suitcase, you cannot stuff things in and hope for the best — the console will simply refuse to install the fifth game until you delete something you already own. Fix it before you need it, not during a download that fails at 98 percent.
Your Switch 2 at Every Storage Tier: What Actually Fits
Here is what your game library looks like at each storage level. "Large titles" means games in the 50–90 GB range — which now includes most major third-party releases and several sports franchises:
Storage Setup | Total Capacity | How Many Top Titles Fit | After One Update Cycle | The Reality |
256 GB internal only | ~220 GB usable | 3 large games — fewer if one is FF7 Rebirth (92 GB) | One major patch pushes you over the edge | You are managing storage by your second week of ownership |
Internal + addlink 256 GB microSD Express | ~470 GB | 6–8 large titles comfortably | Breathing room for a full season of releases | Buys real time, but a heavy download year fills it |
Internal + addlink 512 GB microSD Express | ~730 GB | 10–12 large titles without juggling | Multiple update cycles pass before you notice | The sweet spot — most players never outgrow this |
Internal + addlink 1 TB microSD Express | ~1.2 TB | 16–20+ large titles with room to spare | Storage becomes invisible for the console's lifetime | Your entire Switch 2 library fits. Period. |
The jump from the first row to the third is the difference between a console you manage and a console you play. Expanded storage does not make the Switch 2 faster or prettier — it removes the one constraint that turns a great portable console into a rotating door of installs and deletes.
Why microSD Express Matters — and Why Your Old Card Cannot Help
The original Switch used microSD cards on a UHS-I bus — a standard that maxes out at roughly 100 MB/s. At that speed, loading a large game took noticeably longer from a card than from a cartridge. The Switch 2 changes the interface entirely. Its microSD Express slot uses PCIe Gen 3 — the same bus technology that drives NVMe SSDs in laptops and desktops. The speed ceiling jumps from 100 MB/s to over 800 MB/s. That is not an incremental improvement. It is a platform change.
The addlink Turbo Play microSD Express reads at up to 880 MB/s and writes at up to 750 MB/s. At those speeds, load times from the card are functionally identical to internal storage — the bottleneck shifts from the storage bus to the game engine itself. Available in 128 GB, 256 GB, 512 GB, and 1 TB, the Turbo Play uses the SD 7.1 specification and PCIe Gen 3 NVMe interface that the Switch 2 requires. When inserted in a non-Express device, it falls back to UHS-I mode automatically — a detail that matters if you also use a card reader for file transfers.
For gamers who also play on PS5 or PC: the storage conversation does not stop at portable. If your PS5 expansion slot is empty or your PC build is running a single drive, you are facing the same file-size pressure on a different screen. The addlink A93 NVMe SSD covers the Gen4 console and desktop side at 7,400 MB/s sequential read — and pairing it with an addlink DDR5-5600 memory kit closes the last bottleneck in a multi-platform setup. Storage solved on the Switch 2, storage solved on the desktop. One vendor, both problems handled.
How to Set Up Your Switch 2 Storage the Right Way
Step 1 — Check your current situation before you buy anything. On your Switch 2, go to System Settings → Data Management and look at how much internal storage is free. If you have already downloaded three or more large games, you are likely under 50 GB of free space — which means the next major release will trigger a storage management prompt before it can install. Knowing the number before you shop prevents buying a card that is too small for what you actually need.
Step 2 — Choose your capacity based on how you play, not how you play today. If you mainly play Nintendo first-party titles with occasional third-party downloads, the addlink Turbo Play 512 GB gives you roughly 730 GB total — enough for the full Switch 2 lifespan without storage stress. If you download aggressively, keep everything installed, and play across multiple genres, the 1 TB card gives you over 1.2 TB total and removes storage from the conversation permanently. Think about year three of the console, not month three.
Step 3 — Install the card and set it as the default download location. Power off the Switch 2. Insert the microSD Express card into the slot on the top of the console — it clicks into place. Power on, and the console detects and formats the card automatically. Then go to System Settings → Data Management and set the microSD Express card as the default save location for new downloads. This ensures every future game install goes to the expansion card first, keeping internal storage free for system operations and save data.
Step 4 — Move existing games to the expansion card. In Data Management, select the games currently installed on internal storage and move them to the microSD Express card. At 880 MB/s write speed, transferring a 50 GB game takes about a minute. Once moved, the games load and run identically — there is no performance penalty. This frees internal storage for system updates and new saves while your entire library lives on the expansion card.
Frequently Asked Questions
1. Can I use my old Nintendo Switch microSD card in the Switch 2?
No. The Switch 2 uses a microSD Express slot, which is physically different from the standard microSD slot on the original Switch. Standard UHS-I and UHS-III microSD cards will not work. Nintendo has confirmed this incompatibility directly. If you have a large microSD card from your original Switch, it will not transfer to the new console — you need a microSD Express card specifically. The addlink Turbo Play microSD Express is built to the SD 7.1 specification that the Switch 2 requires.
2. Why are Switch 2 game files so much larger than original Switch games?
The Switch 2 runs games at significantly higher resolutions with more detailed textures, higher-polygon models, and more complex audio. The original Switch rendered most games at 720p in handheld mode and 1080p docked. The Switch 2 targets 1080p handheld and up to 4K docked. Higher resolution means larger texture files, which are typically the single biggest contributor to install size. Third-party ports — titles like Cyberpunk 2077, Final Fantasy VII Rebirth, and Elden Ring — are arriving with asset quality much closer to their PS5 and Xbox versions, not the heavily compressed Switch originals. The file sizes reflect that upgrade.
3. Does game performance differ between internal storage and a microSD Express card?
For most games, no. The Switch 2's microSD Express slot uses PCIe Gen 3 — the same bus technology as internal storage. A microSD Express card running at 800 MB/s or above delivers load times functionally identical to internal storage for the vast majority of titles. This is a generational leap from the original Switch, where microSD cards ran at 100 MB/s on UHS-I and created noticeably longer load times compared to cartridges. With microSD Express, the performance gap is effectively closed. The addlink Turbo Play reads at up to 880 MB/s — close enough to internal speeds that you will not notice a difference in practice.
4. I mostly play Nintendo first-party games. Do I still need expanded storage?
First-party games are smaller, but they still add up. Mario Kart World is 23.4 GB. Donkey Kong Bananza is 10 GB. Super Mario Party Jamboree is 7.7 GB. Those three alone are over 41 GB — and that is just the launch window. Over the console's five-to-seven-year lifespan, Nintendo will release dozens of first-party titles, and later entries in the generation tend to be larger as developers push the hardware further. If you also download system updates, DLC, screenshots, and any free-to-play titles, the internal storage fills faster than you expect. A 256 GB or 512 GB microSD Express card gives first-party-focused players room to grow without ever managing storage.
5. What happens to my save data if I run out of storage?
Save data lives on the Switch 2's internal system memory and cannot be moved to a microSD Express card. Running out of storage does not delete your saves — but it does prevent you from downloading new games, installing updates, or downloading DLC until you free space by deleting installed software. The console will prompt you to delete something before it can proceed. Your saves are safe, but your ability to play new content stops until you make room. An expansion card prevents this bottleneck entirely by keeping game installs off the internal storage.
The Verdict: What to Buy Before Your Storage Runs Out
Here is the short version:
If you play a mix of first-party and third-party games and want room to grow: The addlink Turbo Play 512 GB microSD Express is the sweet spot for most Switch 2 owners. At 880 MB/s read speed on PCIe Gen 3, load times match internal storage. 512 GB of expansion plus 256 GB internal gives you roughly 730 GB total — enough for ten to twelve major titles without juggling installs. This is the card that lets you stop thinking about storage and start playing.
If you download everything and delete nothing: The addlink Turbo Play 1 TB microSD Express is the set-it-and-forget-it option. Over 1.2 TB of total storage means your entire Switch 2 library — first-party, third-party, free-to-play, DLC, updates — lives on the console at once. No rotating installs. No "which game do I sacrifice" decisions. This is for the player who buys games faster than they finish them and never wants to see a storage warning.
If you game across Switch 2 and PS5 or PC: Pair the addlink Turbo Play 1 TB microSD Express for your Switch 2 with an addlink A93 NVMe SSD for your PS5 or PC build. The A93 handles Gen4 console and desktop loads at 7,400 MB/s — and when you add a DDR5-5600 memory kit for the PC side, your multi-platform setup is covered from portable to desktop without a storage bottleneck on any screen.
The Switch 2 is the most capable portable console ever made. Its storage capacity is the one thing that does not match the ambition. Fix it once, fix it early, and never think about it again. Browse the full addlink microSD Express lineup at addlink.com.tw.
