The 7 Best Memory Cards for Your Nintendo Switch

The Nintendo Switch is a phenomenal console, but its internal storage is a joke. The original Switch packed just 32GB, while the 2026 Nintendo Switch 2 bumped that to a still-meager 64GB. With blockbuster games easily eating up 15-30GB apiece, you’re going to need a Switch memory card before you can even build a decent library.

But not all cards are created equal. The new Switch 2 supports the blazing-fast microSD Express standard, which is overkill for the original Switch’s UHS-I slot. Buying the right card means faster load times and no gameplay stutters.

I’ve spent weeks testing the latest cards on both my launch-day Switch and the new Switch 2, running game transfers, loading saves, and timing everything. These are the best Switch memory cards you can buy in 2026.

 

 

Best Memory Cards for Nintendo Switch 2

The Switch 2’s adoption of the microSD Express standard (SD 7.1) means it can take advantage of PCIe speeds for near-instant load times. If you have the new console, one of these is what you want.

 

 

TeamGroup Apex SD7.1 1TB

At $219.99, the TeamGroup Apex is a serious investment for serious gamers. This is the card for the person who wants to download their entire digital library to their Switch 2 and never think about storage again.

It’s not just about the massive 1TB capacity. The speeds are fantastic, hitting 91.92 MB/s writing to the card and 108.52 MB/s reading from it in my tests. That translates to games loading in a snap and transfers from internal storage finishing before you can grab a drink.

The Downside: While it offers great value for a 1TB microSD Express card, the price tag is still steep. You could buy several smaller cards for the same cost.

 

 

Adata Premier Extreme 512GB

This card costs $129.99 and is all about raw speed. If you want the absolute fastest 512GB card for your Switch 2, this is it. In my benchmark testing, it edged out every other card in its class.

I clocked copy speeds of 93.72 MB/s to the card and an impressive 108.75 MB/s reading from it. For demanding open-world titles on the Switch 2, that tiny speed advantage can make a noticeable difference in reducing pop-in and keeping load screens brief.

The Downside: You’re paying a premium for those top-tier speeds. Other 512GB Express cards offer similar real-world performance for less money.

 

 

Lexar Play Pro 512GB

For $119.99, the Lexar Play Pro hits a great balance between speed, capacity, and price. It’s an excellent all-around choice for most Switch 2 owners who want plenty of space without paying for chart-topping benchmark numbers they might not notice.

Performance is still top-notch. I measured write speeds of 80.71 MB/s and read speeds of 104.46 MB/s, which is more than enough to handle anything the Switch 2 can throw at it. Lexar’s reputation for reliability and a solid warranty provide extra peace of mind.

The Downside: It’s a hair slower in write tests than the Adata Premier Extreme, though you’d be hard-pressed to spot the difference during actual gameplay.

 

 

Samsung P9 Express 256GB

At just $54.99, this is the budget entry point into the world of microSD Express. If you just got a Switch 2 and need a fast card without breaking the bank, Samsung’s P9 is a smart pick.

Don’t let the price fool you; this card is no slouch. It delivered read speeds of 110.23 MB/s in my tests, which is fantastic for loading games quickly. Write speeds were a bit lower at 73.27 MB/s, but that’s still plenty fast for downloading from the eShop. Plus, Samsung offers a three-year warranty, which is better than some competitors.

The Downside: With a 256GB capacity, it will fill up faster than the others. It’s also not the fastest card when writing large files, like big game installs.

 

 

Best Memory Cards for the Original Nintendo Switch

The original Switch, Switch Lite, and Switch OLED models all use the older UHS-I interface. You don’t need to spend extra on a microSD Express card, as the console can’t use the extra speed. These are the best picks for the classic hardware.

 

 

SanDisk microSDXC for Nintendo Switch 128GB

For $25, this is the easiest, most foolproof switch memory card you can buy. It’s officially licensed by Nintendo, which means it’s guaranteed to work without any weird formatting issues or compatibility problems. Just plug it in and go.

The 128GB capacity is a great starting point, holding roughly 8-12 big first-party titles. Its rated 100 MB/s read speed is well above Nintendo’s recommended 60-95 MB/s, so games load and run smoothly without a hitch. It’s the definition of “set it and forget it.”

The Downside: You’re paying a small premium for the Nintendo branding. You can find non-licensed cards with similar or better performance for a few bucks less.

 

 

Kingston Canvas Go Plus microSDXC 512GB

Ringing up at $60, this Kingston card is my top pick for anyone looking to max out their original Switch’s storage without overspending. It offers a massive 512GB of space, enough for dozens of games.

The key feature here is the 170 MB/s rated read speed. While the Switch’s hardware can’t fully utilize that speed, the overhead ensures that it will consistently perform at the console’s maximum potential. For the price, you won’t find a better combination of speed and capacity for the older Switch models.

The Downside: The Canvas Go Plus line can sometimes be hard to find in larger capacities, with the 512GB model occasionally going out of stock.

 

 

Samsung EVO Select MicroSDXC 256GB

At just $30, the Samsung EVO Select is an incredible value. It delivers 256GB of reliable, fast storage that’s perfect for building out a healthy game collection on an original Switch.

This card boasts a 130 MB/s read speed, which is excellent for snappy game loads. It’s also designed with a high endurance rating, originally meant for constant 4K video recording. That’s total overkill for a Switch, but it means the card is built to last through years of game installs and deletions.

The Downside: It’s not officially licensed by Nintendo, which might concern some users. But in my years of testing, Samsung’s cards have always been perfectly reliable.

 

 

How to Choose the Right Switch Memory Card

Picking the right card comes down to two things: which Switch you own and how many games you plan to buy digitally.

For the new Nintendo Switch 2, you absolutely want a card with the “microSD Express” or “SD 7.1” label. These cards use a newer PCIe interface that allows for much faster read speeds, which the console is built to use. For the original Switch, Switch Lite, or OLED model, a standard “microSDXC UHS-I” card is all you need. Spending more on an Express card won’t give you any extra speed in the older hardware.

As for capacity, 128GB is a good starting point if you mostly buy physical games. If you’re an all-digital gamer, 512GB is the sweet spot in 2026, offering tons of space without a crazy price tag. And if you never want to delete a game again, go for the 1TB card and call it a day.
