Samsung is renowned for its storage media, and the Samsung Evo+ 256GB UHS-I microSDXC U3 memory card is no exception. This SD card isn’t the fastest on this list, though with 95MB/sec read speeds and 90MB/sec write speeds, it’s perfectly acceptable, and the one I’d trust most readily with my data. It’s rugged, reliable, and offers a respectable quantity of storage space. It’s water, temperature, X-ray, and magnet proof, so you don’t have to worry about losing your games no matter what punishing conditions this card is used in.

What We Like
  • Certified by Nintendo

  • Fast loading for games

What We Don't Like
  • Expensive

This bright yellow switch branded SanDisk card really stands out from the crowd, and for good reason. The SanDisk 256GB MicroSDXC UHS-I Memory Card is purpose made for the Nintendo Switch and is certified by Nintendo. That’s as big of a guarantee of maximum compatibility with your Switch as you’re likely to find, and it’s backed up by an excellent warranty from SanDisk.

Additionally, this SD card is no slouch when it comes to speed, with 100MB/s read and 90MB/s write speeds, so you won’t have to wait around for games to load. The only downside to this card is that the Nintendo branding comes with a price hike over a standard SanDisk card.

What’s surprising is just how cheap this card is, costing little more than a 256GB card and offering half again the capacity. This is easily the best value card you can buy for the Switch.

SanDisk Ultra PLUS 256GB
What We Like
  • Plenty of capacity

  • Tough design

  • Good warranty

What We Don't Like
  • A little slow

It’s easy to recommend the SanDisk Ultra PLUS 256GB microSDXC UHS-1 memory card if you’re looking for this level of capacity. SanDisk makes great, trustworthy products and this SD card is no exception. It’s backed up by SanDisk's excellent warranty and is ruggedly designed to resist drops, submersion in water, extreme temperature, and even X-rays. Though not amazingly fast, its 95 MB/sec data transfer rate keeps load times to a minimum and 256GB is plenty of capacity in which to store games, photos, videos, and more.

Biggest Capacity: SanDisk 1TB Extreme MicroSDXC UHS-I Memory Card

What We Like
  • Nearly bottomless capacity

  • Blazing fast

  • Durable

What We Don't Like
  • Costs more than a Nintendo Switch Lite

If you want the best of the best and money is no object, then the SanDisk 1TB Extreme MicroSDXC UHS-I Memory Card is the obvious choice. It’s hard to fathom just how bottomless a full terabyte of storage space truly is—with this SD card you’ll easily be able to fit your entire Switch game library onto it with room to spare for years worth of screenshots and video clips of your best gameplay moments. That’s not all, though, as this card will give you blazing fast 160MB/s read speeds that’ll make accessing those reams of data no problem. It’s tough, as well, with resistance to shocks, water, and everything else the world can throw at it.

The only downside is the eye-watering price tag. At more than $230, this card is more expensive than a brand new Nintendo Switch Lite, but for the dedicated gaming enthusiast with deep pockets and a huge game library, this is the obvious choice.

Capacity: 1TB | Read/Write Speeds: 160/90MB/s | Class: U3

Fastest Card: PNY 128GB Elite-X Class 10 3 V30 microSDXC

What We Like
  • Class 10 U3 microSD card

  • Supports 100MB/s read speed

  • Allows apps and games to run and load faster

What We Don't Like
  • Overkill for most Switch users

While the Nintendo Switch is hardly a demanding console, if you want the peace of mind of making sure that your games won't suffer from stuttering or slow loading, you can't do better than the PNY 128GB Elite-X. It's a Class 10 U3 microSD, meaning it has an impressive 100MB/s read speed. That should give you the ability to load games and move files within the blink of an eye. Aside from the Nintendo Switch, it's fast enough that you can use it for sharing content between devices, 4K video recording, and use in devices like the GoPro.

Capacity: 128GB | Read/Write Speeds: 100MB/s read, write unspecified | Class: 10 U3

Best Durable: Netac 128GB MicroSD Card

What We Like
  • Durable

  • Fast read speeds

  • Inexpensive

What We Don't Like
  • Write speed is on the slower side

There are few things more irritating as a gamer than losing progress. Whether it's due to a hardware lock up, a game crashing, a server hiccup...or splashing your drink on an SD card. This little wonder from Netac is designed to avoid exactly that horrifying situation; it's not just waterproof, but also shockproof, temperature-proof, and even X-ray-proof, so it won't get accidentally wiped when you take your Switch on vacation. Because while losing progress is a pain, it's nothing compared to losing an entire card full of games, saves, and screenshots.

The Netac is fast, too, with read speeds up to 100MB/s, and each card is individually factory tested to ensure quality. It's also relatively inexpensive, so you can save your money for what actually matters: buying more games.

Capacity: 128GB | Read/Write Speeds: 100/30MB/s | Class: 10 U3

Best Budget: Lexar Professional 667x 128GB microSDHC

Lexar Professional 1000x 32GB microSDHC UHS-II Card (LSDMI32GCBNA1000A)
What We Like
  • Cheap

  • Extremely fast load times

  • Includes data recovery software

What We Don't Like
  • Small capacity

  • Poor value for capacity

If you’re on a tight budget, the Lexar Professional 1000x microSDHC 128GB UHS-II/U3 provides blazing-fast performance at a very affordable price point. Compared to much larger capacity cards mentioned on this list, 128GB seems like nothing, but keep in mind that with this much capacity you're more than doubling the native capacity of the Switch. With that said, it’s worth considering that, though this is a cheap budget option, it does represent poor value given its price to capacity ratio.

What makes this SD card really special is its 100MB/sec read speed, which is great. It drastically reduces load times and beefs up data transfer speeds to make short work of any task to which it’s turned. Lexar also provides increased peace of mind by offering an excellent warranty and a free downloadable copy of their Image Rescue Software so that if something does go wrong you can recover your data.

Capacity: 128GB | Read/Write Speeds: 100/90MB/s | Class: 10 U3

Final Verdict

The Samsung Evo+ 256GB UHS-I microSDXC U3 (view on Amazon) beats out faster cards and higher capacity cards by offering the perfect middle ground between price, capacity, and performance. The Samsung brand and the pedigree that comes with it make this card a no brainer default Switch card. However, if you’re looking for maximum speed, the SandDisk Extreme 1TB Extreme MicroSDXC UHS-I Memory Card (view on Amazon) is second to none, so long as you can stomach the sky-high price.

  • How much does a microSD card cost for the Nintendo Switch?

    A microSD card doesn't have to break the bank. If you plan to get mostly physical cartridges, then a microSD card slot as small as 32GB is fine since all you need to do is accommodate any save game files and screenshots. But if you plan on doing a mix of digital download and physical, we'd recommend at least a minimum of 128GB. Our most affordable card on this list is the 32GB Lexar Professional which costs just $40.

  • How to reset a microSD card?

    If you want to use an existing microSD card on your Nintendo Switch, reformatting it is an easy matter. Insert your microSD card into an SD card adapter (or microSD card slot on your laptop if it has one), then put it in your PC. Hit Start>Computer and right-click the microSD card. Then hit format. You'll get asked if you want to reformat is, just say yes, and all the old data on your microSD card will be wiped and it'll be good as new for your Switch.

  • Where does a microSD card go in the Switch?

    The microSD card slot is hidden behind the Switch's stand. Make sure your Nintendo Switch is off, open up the stand, and you should see the microSD card slot right there at the bottom. Just insert your card with the microSD card logo facing away from the console and you should be good to go.

What to Look For in SD Cards for Nintendo Switch


Look around any internet storefront and you’ll find more obscure brands of SD cards than you can shake a stick at. However, it’s always a good idea to stick with a trusted brand with proven reliability. Saving a few bucks on a sketchy off-brand card isn’t a good value if you end up losing all your data. When in doubt, buy from a recognizable brand like Samsung, SanDisk, or PNY. Amazon, in particular, has become somewhat known for having cards that aren't legitimate, so it's always worth doing a test of read/write speeds to make sure you're getting the card that's advertised.


Your budget is really your only limit to storage capacity on SD cards. However, it’s not always wise to shell out hundreds of dollars for terabytes of data. Often super high capacity comes at the cost of speed, and you probably don’t need that much storage space anyway. A 256GB card offers a good balance between price, performance, and storage capacity. If your needs are more modest, a 64GB card could cut it. If you plan to have an all-digital library, then a 512GB or even 1TB card wouldn't be amiss.


Most modern SD cards offer enough speed, but as a rule of thumb 90MB/s should be considered the minimum for read and write speeds. Remember that the faster the card the quick the load times and the better your Switch will function. Write speeds tend to be lower than read speeds, but for gaming purposes, the read speeds are more important. Most of the cards on this list are Class 10 and many are U3, meaning they offer read/write speeds that are three times as fast as regular U1 Class 10 cards.
