If you want to add more storage to your Nintendo Switch 2, you’ll need a new microSD Express card. Here’s what you should know before you buy one.
The Nintendo Switch 2 comes with 256GB of built-in storage, eight times more than the original Switch and four times more than the Switch OLED. But the new console’s improved performance means that some games will hog a ton of that space: Cyberpunk 2077 is a 60GB download, for one, while Split Fiction checks in at 73GB. Other titles aren’t nearly as big, but chances are you’ll eventually want to add more room to the device.
When you do, you’ll need a microSD Express card. These are not the same as the standard microSD cards you may have bought for the first Switch or other gaming handhelds — they’re newer, faster and significantly more expensive. But if you want more space, they’re your only choice. If you’re looking to grab one today, we’ve laid out the best microSD cards for the Switch 2 and broken down what you should know before you buy.
The Switch 2 is the first mainstream device to require microSD Express for storage expansion, so there aren’t many options available to buy just yet. To make things easy, here’s a list of every microSD Express card we’ve seen at retailers at the time of writing:
Remember: You’re looking for microSD Express, not “Extreme,” a la the branding SanDisk uses for some of its conventional microSD cards. A microSD Express card will have a big “EX” logo printed on it — if you see that, you should be good to go.
Nintendo says the Switch 2 technically supports cards with a capacity up to 2TB, but we haven’t seen any microSD Express model go beyond 1TB just yet. It’s also worth noting that GameStop and Onn (Walmart’s in-house electronics brand) aren’t manufacturers, so it’s unclear who exactly is making their cards.
Currently, stock for each of these cards has been extremely spotty. SanDisk’s microSD Express Card has also increased in price since it first went up for sale in February; originally, it cost $45 for 128GB and $60 for 256GB. Either way, all of these cards are far pricier than traditional microSD options. The Samsung Pro Plus, for example, costs $17 for 128GB, $25 for 256GB, $43 for 512GB and $90 for 1TB as of this writing.
We’ve already tested SanDisk’s Express card and the Lexar Play Pro for our broader guide to the best microSD cards. Between the two, SanDisk’s card has much faster sequential read speeds — up to 899 MB/s vs. 712 MB/s in CrystalDiskMark, to name one benchmark — which theoretically makes it better equipped to reduce load times.
The Play Pro is quicker for sequential writes (up to 720 MB/s vs. 650 MB/s), available in more sizes and should be cheaper at 256GB whenever it’s in stock.
