The Nintendo Switch 2 isn't compatible with the best Nintendo Switch SD Cards. Instead, the brand-new handheld relies on speedier MicroSD Express Cards, which can be pricey, and not everyone has the means to make the next-gen upgrade right now. If you're not ready to grab the best Nintendo Switch 2 MicroSD Express Cards, sticking with one of the best SD Cards can help rejuvenate your older Switch before you’re ready to make that next-gen leap.
Through our own testing, we worked out that the average first-party original Nintendo Switch game sits at around 6.7GB, so it's fairly easy to work out which size you need based on your current or future library. Indie games tend to be far smaller, so there's wiggle room here as well. The best Nintendo Switch SD cards can expand the older handheld all the way up to 2TB. Of course, very few Ninty fans need that much space, unless you're also fond of taking a lot of screenshots and video clips.
While it's disappointing that one of the best Nintendo Switch accessories isn't compatible with the Switch 2, you can pop your older SD Cards into the Switch 2 to transfer screenshots and clips - so don't throw any of these away just yet if you're thinking of making a next-gen upgrade.
The Quick List
With space for around nine* full-sized first party games (but plenty more indies), this 64GB card is best for those just starting out.
You'll get around 18* first party games on this 128GB card - making it a solid choice for those who dabble in eShop downloads semi-regularly.
Typically, the smaller the storage capacity, the less expensive storage will be, but Amazon takes that to a whole new level with its Amazon Basics microSD line - which is pretty much as cheap as it gets.

This 200GB card will fit somewhere between 25 and 30* full-sized titles, so it's best for those who buy the majority of their games digitally.
1TB is enough space hold roughly 150* first party games. That makes this Silicon Power option best for those who don't want to think about upping their storage in the future.
128GB is still enough space for around 18 first-party games - but this micro SD separates itself from the rest by sporting an official Super Mario design, making it the best looking microSD of the bunch.
While new to the GamesRadar+ hardware team, I've been reviewing and getting hands-on with the Nintendo Switch, and Nintendo tech almost during my entire time as a gaming tech writer. As someone whose Switch library is bursting at the seams, finding the perfect amount of extra storage is a fine art that should be shared.
June 16 - With the Nintendo Switch 2 now in the wild, I updated this page to emphasize the fact that the new handheld cannot read older SD cards, and instead requires microSD Express Cards for additional storage purposes. Additionally, I also upgraded the FAQ section to reflect the new handheld releases and its these new requires if you need extra storage.
May 19 - With the Nintendo Switch 2 closer than ever, the attention has turned to the new microSD Express Cards required for the new handheld. Regardless, I updated the best Nintendo Switch SD Card guide to include the Amazon Basics 256GB card as the best budget option. While it's speeds aren't the fastest, it's one of the most affordable options for those looking for new Switch storage without breaking the bank.
The best Nintendo Switch SD card for a storage boost
✅You prioritize buying physical Switch carts: If you prefer your physical Switch games, an extra 64GB boost is perfectly fine to download any additional updates for your favorite first-party games.
❌You play mostly digital only: If you prefer to buy everything from the eShop, including the latest first-party Nintendo games, you're gonna need something with a larger storage capacity from the get-go.
❌You've got a huge Switch game backlog: Even though you can archive your digital downloads, if you like all your Switch games in one place, 64GB won't be enough for a large mix of both first-party and indie games.
64GB Nintendo Switch memory cards are about as small as you'll want to go. They double the storage space on an OLED device, but in the grand scheme of things they're still pretty restrictive. They are, however, the cheapest way to upgrade your storage.
It's a storage boost for those who generally buy cartridges rather than running full first party titles from the eShop, but still want to download a few smaller indies. If you're going for the big Ninty releases, you'll get somewhere between 7-10 games on here, depending on individual install sizes - but considering smaller experiences can barely leave the 1GB mark there's plenty more room for others.
A 64GB card isn't going to last forever, but if you don't want to spend too much cash on your first upgrade and won't be downloading more than a couple games a month over the next year or so then it's the cheapest way to go.
The best Nintendo Switch SD card for eShop fans
✅You're on a budget: Nintendo Switch-compatible SD cards keep getting more affordable, and fortunately, even with over 100GB of space, a 128GB card is still just a fraction of the cost of a brand-new Switch game.
❌You take a ton of screenshots and video clips: If you like your screenshots and short game clips, 128GB can fill up fast, and won't give you much extra room for your first-party Switch downloads on top of that.
Sandisk is one of the biggest and best names in MicroSD cards, and this is the best value model you can buy. For about $20 / £20 you get 128GB of storage, a reliable MicroSD card with decent file transfer speeds. Plus, you even get an adapter should you want to use this in an SD-based device like a digital camera or should you have the urge to transfer all of your favorite screenshots and video clips to your laptop. That makes it hugely versatile. Nintendo partnered with SanDisk for the official SD card for Switch, so it's a make Ninty trusts too. And yes, we have tested this MicroSD card and it 100% works with your Switch.
Best budget Nintendo Switch SD Card
✅ You don't care about the aesthetic of your storage: The Amazon Basics line doesn't have 'basic' in the name for no reason. This is a totally un-flashy microSD, which focuses on just providing that 256GB of storage and that's that.
❌ You'd rather get the 1TB version: Amazon has not just the 256GB microSD card at a budget-friendly cost, but this line goes up to 1TB if you need more space for your favorite Switch games.
The Amazon Basics line of microSD cards is as just like the name suggests - basic. The line only comes with all the basic necessitates of any microSD card, a pretty basic design and pretty basic speeds, but that's what helps keep costs low to make it best best SD card available for the original Switch today.
Modern microSD cards by brands like Sandisk can almost double the speeds of this card, even with the iconic storage tech brand's own 256GB equivalent card. But, it's pretty hard to out-do the Amazon Basics line when it comes to being budget friend, as this microSD manages to bring 256GB to the table while keeping costs below $20 / £20.
Again, this card's read and write speeds of 100MB/s and 90MB/s respectively are nothing to write home about. But if you're sticking to your original Switch and not making that next generational leap with the Nintendo Switch 2 because you have a strict budget to stick to, this is an ideal way to still get extra space for your games without breaking the bank.
The best Nintendo Switch SD card for eShop Pros
✅ You play a mix of physical and digital Switch games: Having a 200GB MicroSD card at your disposal is plenty for a mix of both updates for your physical games, and even digital versions of some of the biggest-sized Switch games available on the eShop.
❌You have a massive Switch backlog: If you prefer to keep every game on your Switch, no matter if you played it recently or not, 200GB may still not be enough for your ever-growing backlog of games.
Hitting the ‘Goldilocks window’ for Nintendo Switch SD cards (being more than big enough for most game storage needs, but remaining at a price that’s entirely fair), the 200GB SDXC will evaporate all your storage worries for a long time. For the price of roughly one AAA Nintendo Switch game, you’ll get a home for dozens and dozens more – you could fit Super Mario Odyssey on this thing 33 times. If you’re not on a particularly tight budget, and want a robust Nintendo Switch memory card that still won’t cost the Earth, this is the one to go for. It's worth noting that the cost of SD cards continues to fall, so you can pick this one up much cheaper today than it was 6 months ago, so it's worth stretching your budget a little.
The best Nintendo Switch SD card for future proofing
✅You want the biggest storage possible: MicroSD cards bigger than 1TB are still a bit of an anomaly, so this is your best bet for the largest extra space your Switch can handle. Unless you never archive a game on your Switch and download every first-party title the eShop has to offer, this will more than support your storage needs.
❌You're on a tight budget: MicroSD cards may get more affordable all the time, but 1TB is still going to set you back a lot of hard-earned cash. These high-capacity cards can cost upwards of two brand-new Switch games worth. That's a lot if you're already spending a lot on the latest releases.
If you're ever thinking about being completely, utterly, and totally future-proofed in terms of your Switch's capacity then the Silicon Power 1TB Superior SD card is for you. Yes, the 1TB capacity will mean it is a larger investment by default to begin with but the sheer value here is ridiculous, and you'll literally never have to worry about storage space again. Pop this in and even the most storage conscious of future-proof worried among us will have their minds eased.
With Nintendo still bringing out bangers, even at the tail-end of the Switch's lifespan, 1TB will have you more than prepared, especially if you prefer your digital downloads over physical carts. Whether it's The Legend of Zelda: Echoes of Wisdom, Mario Party Jamboree, or Mario & Luigi: Brothership, you'll be at ease knowing 1TB will more than be enough for Nintendo's recent releases, and then some.
The Superior 1TB SD card also comes with an adapter so you're good to go with any kind of mobile device or laptop should you need to shift gears, and there's a five-year warranty so you can have peace of mind. Simple, massive stuff.
Note: The stock of this Nintendo Switch memory card is fluctuating wildly at retailers right now but it is usually out there, seen in the wild. You may have to bookmark this page and refollow the links after giving it a chance to come back into stock. It'll be absolutely worth it - good luck!
The best looking Nintendo Switch SD card
✅You want your microSD card to look its best: For those who need all of their gaming accessories to look the part, SanDisk created a line of cards officially licensed for the Switch that feature charming designs based on Nintendo properties, like this red Super Mario mushroom microSD card.
❌You don't want to pay more for a nice design: While this microSD card may look great, picking it up means you're paying slightly more just for the cute design. If you care more about the actual storage requirements and speeds, especially as you'll rarely see the SD card once it's actually in your Switch, then picking up the non-officially licensed equivalent is a better plan.
When it comes to the best microSD cards, how the card actually looks likely won't matter to everyone - especially where the Nintendo Switch is considered. Once you've inserted your microSD card into any model Switch, you're never going to see it again unless you frequently swap between multiple cards at a time.
Regardless, SanDisk and Nintendo thought of everything and have a whole line-up of officially licensed cards for those who care. This Super Mario mushroom design is just one of a whole array of microSD cards based on Nintendo properties, varying in all the usual storage variants you can imagine. Outside of the flashy designs, there's not much going on that separates them from their non-licensed counterparts.
This red microSD card still sports read and transfer speeds up to 100MB/s, write speeds up to 90MB/s, and 128GB worth of space for all your eShop game downloads. The only difference you'll find here is in its design, and if your microSD needs to look as flashy as your Switch case, then this, and the rest of the officially licensed Nintendo Switch memory card line, are the best looking cards you can get your hands on.
*Based on an average of 6.7GB per title, allowing for unusable storage space on the card itself
The best Nintendo Switch SD Cards Coming Soon
Nintendo: The Nintendo Switch 2 is finally here, and launched worldwide on June 5, 2025. As I briefly touched on within the introduction to this guide, the new handheld relies on new, speedier microSD Express Cards for extra storage. While you can technically pop in your older SD cards, you won't be able to store any Switch 2 games on them, and can only use them to transfer over screenshots and original Switch game clips instead.
With that in mind, the focus has shifted to these new microSD Express Cards. These new cards are available up to 1TB so far, with only 256GB officially licensed models from SanDisk and Samsung currently on the market. Of course, as microSD Cards aren't just for Nintendo hardware, there was already a wealth of additional microSD Express Cards available to purchase right well before the new handheld's release from brands like PNY and Lexar.
Upcoming Nintendo Switch SD Card reviews: With all the focus on the new Nintendo Switch 2, you can imagine that means there's less new storage solutions for the current Switch on my testing bench - and you'd be right. Currently, I have a 256GB microSD Express Card at my disposal, which is being put through its paces with the new console.
The focus on the new form of SD cards doesn't mean the original family of Switch handhelds will be forgotten, of course. Especially as the introduction of more Switch 2 aimed cards will likely mean that we'll see SD cards for the original Switch get even cheaper in the near future.
How to choose the best Nintendo Switch SD card
When it comes to choosing the best Nintendo Switch SD card for your Switch, you'll want to make sure you're getting the right memory card size for your playstyle and existing library.
For example, if you generally stick to indie games and smaller releases you'll be able to get away with a 64GB or 128GB card a lot easier than someone who plays all the first party games. Official Nintendo Switch games generally scale between 5GB and 10GB of space, and some can go a little beyond this as well. However, if you already know you prefer to buy most of your games physically you can scale down your required storage a little.
We'd recommend a 128GB or 200GB card for most users, giving you a good spread of first party downloads and bags of space for smaller installs. That's with a handful of physical games thrown in - if you're going all digital and regularly pick up new releases you might want to invest in a one-and-one 1TB option.
Of course, if you're a die-hard Nintendo collector, you can also pick between one of the official cards. The licenced SD cards feature iconography from the Super Mario Series, Animal Crossing and The Legend of Zelda, but I'd only recommend choosing these above the rest if you're a dedicated Ninty fan. They make look better than other cards, but their flashy looks comes at a higher price point than those of the exact same storage size.

SanDisk is partnered with Nintendo to bring official versions of its MicroSD cards to market. There are a range of different sizes on offer, starting at 64GB and now spanning all the way up to 1TB, all featuring icons from different Nintendo franchises on the card itself. These official Nintendo Switch memory cards just aren't worth it, though. Besides from some fancy colors they're essentially the same as SanDisk's main range, but generally cost a little extra. You won't see that cute Animal Crossing leaf when it's whirring away inside your console, after all.
