The best Nintendo Switch SD cards in 2024

Whether you're prepping for an eShop haul or just want to future proof your console, Nintendo Switch SD cards can vastly expand your system's memory on the go. Not only that, but they're a must-have if you consider the Switch's limited internal storage. 

We've worked out that the average first party Nintendo Switch game sits at around 6.7GB (though there are outliers on either side of that figure), so it's fairly easy to work out which size you need based on your current or future library. Indie games are tend to be far smaller, so there's wiggle room here as well. 

The best Nintendo Switch SD cards can expand your system all the way up to 2TB. Of course, very few Ninty fans need that much space. In fact, many can get by on 128GB if splitting between downloads and game carts, potentially upgrading to 200GB or 256GB further down the line. While this is one of the best Nintendo Switch accessories to pick up on day one, you don't need to future proof yourself too much thanks to those relatively low prices.

Nintendo Switch memory cards: FAQ

What size Nintendo Switch SD card should you buy?

Nintendo Switch games typically take up between 5 and 10GB of storage , though larger titles like The Legend of Zelda: Breath of the Wild can use up far more space. 

We'd recommend a 128GB SD card for most users; this will give you enough room for about 15-18 Nintendo Switch games on your console, but it's worth noting that smaller indie titles will take up far less space. If you're going to be playing mostly with physical games, and you don't envision yourself buying too many larger titles from the eShop, you should be able to get by on 64GB. However, if you're going all-digital, a 256GB card will see you through around 35 full sized games.

Are official Nintendo Switch SD cards worth it?

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. 

What is the maximum Nintendo Switch SD card size?

The Nintendo Switch can only run up to 2TB of additional storage in an SD card. However, it should be noted that that's a ton of space, so you'll certainly have to be an eShop pro to fill it to the brim.

Which SD cards are compatible with Nintendo Switch?

The Nintendo Switch is compatible with microSDXC cards over 64GB and microSDHC cards between 4GB and 32GB. That really means that pretty much any SD card you have will slot neatly into your console already. However, if you're buying new it's always recommended to grab one with a Class 1 UHS Speed (you'll see a small bucket with a one inside it on the card itself) for the best experience. 

Nintendo Switch memory card glossary

Even smaller plug and play SD cards like the kind used in the Nintendo Switch can come with a plethora of terms to make the whole buying process more difficult. We're breaking down common jargon here, to make sure you know exactly what you're buying. 

Application Performance (A1 / A2)
The Application Performance Class is denoted on a Micro SD card using 'A1' or 'A2' and refers to the speed at which your memory card can run random read and write functions while also saving as a storage device. The Nintendo Switch is designed to be used with A1 cards, but can use an A2 card (though the user won't experience a benefit). 

GB
A gigabyte is the most widely used unit of digital storage. It equates to 1,024 megabytes. The average first-party Nintendo Switch game sits at between 4 and 7GB.

Read speed
Read speed refers to how quickly a memory card can access the information stored on it. The higher the read speed the better, and results are recorded in megabytes per second. Read sped influences load times. 

SDXC
SDXC is the most commonly used SD card format for Nintendo Switch. The SDXC is similar to an SDHC card but has a higher storage capacity, both can be used in the system.  

UHS (U1 or U3)
The phrase UHS refers to the speed class of a Nintendo Switch memory card, denoted on a card with the letter 'U' and either a 1 or a 3 inside it. A U1 card can run at a minimum write speed of 10MB/s where as a U3 bumps things up to a minimum of 30MB/s. In general, a U3 card is faster than U1, but because the Switch is a fairly lightweight device both cards will run pretty similarly.

Write speed
Your write speed is how quickly your memory card can save information to itself, measured in megabytes per second. This has an influence in how quickly you can save and install downloaded files.
