The 5 Best MicroSD Cards For The Steam Deck

The best microSD cards for the Steam Deck offer the perfect balance of blazing-fast speeds, reliable performance, and ample storage. With this in mind, it doesn’t sound like a complicated decision. Well, for the Steam Deck, it is. Before anything, you should note that Steam deck is a power-focused gadget that runs high-end games and apps.

Valve’s most premium version of Steam Deck runs on a 512GB SSD. That’s quite powerful and fast, but still not enough to run the biggest games without hiccups. So, when adding another layer of storage, it’s wise to choose a MicroSD card that can match the device’s power. Speed, for one, is a big deal. Although the Steam Deck UHS-1 interface limits the maximum speed to about 100 MB/s, the MicroSD card you choose should be able to deliver at least that much.

Most entry-level MicroSD cards can only offer up to 30 MB/s, so looking for cards with higher speeds is essential. Speed aside, storage and A ratings are also critical factors. While you’ll find a 1TB card with decent speeds, One with A2 (Application Performance Class A2) offers better performance than the standard A1.

So, we took time to analyze and compare some of the top MicroSD cards for the Steam Deck and came up with pretty exciting results. Here are the five best MicroSD cards for the Steam Deck:

Best Overall: Lexar Play 1TB MicroSDXC

Offering the perfect balance of speed and capacity is the Lexar Play 1TB MicroSDXC. This high-performance MicroSD card is ideal for any Steam Deck gamer because it uses the UHS-1 interface. The card offers up to 150 MB/s read speed, above the maximum limit of what the Steam Deck can handle.

But that’s okay because it assures you’ll always get a smooth gaming experience no matter how heavy the game you’re playing. And as if that wasn’t enough, the Lexar Play card also comes with an A2 rating for its performance. Basically, an A2-rated MicroSD offers a minimum of 4000 IOPS for random 4K reads and 2000 IOPS for random 4k writes.

Perhaps what we love the most about this MicroSD card is its massive 1TB capacity. That’s enough storage to hold up to 50 AAA games and dozens of smaller titles. But if that’s too much for you, the card comes in 128 GB, 256 GB, and 512 GB storage options. So, no matter your budget or gaming needs, you can always find the perfect card from Lexar.

The high cost of the 1TB versions is a definite drawback here, though. Also, only the 128 GB option comes with an adapter, so you might want to buy that separately. You’ll also need to be careful not to buy a fake Lexar card. It’s not very common, but unfortunately, it does happen.

Speed goes beyond read and write, and the SanDisk Extreme Pro 512GB has it all.

The card also boasts maximum read speeds of up to 200 MB/s, powered by SanDisk’s proprietary QuickFlow Technology.

That means you can transfer large files in no time and get lightning-fast loading speeds in games. Additionally, the card is also U3 rated, meaning it can handle 4K UHD and Full HD video games without any issues. And because of its massive 512 GB storage capacity, you won’t have to worry about running out of space anytime soon.

The card is also waterproof, temperature-proof, X-ray-proof, and drop-proof. Plus, it comes with SanDisk’s Memory Zone app, which makes it easy to manage your memory. We didn’t quite see any downside with this card because it ticks all the boxes. But still, it will cost you around $86.00 for the 512 GB version.

This category was pretty intentional. Because standard gamers don’t need the extra speed and power of an ultra-fast card like the SanDisk Extreme Pro. But at the same time, they don’t want a budget card that lags behind in performance either. Our pick for this category is the Samsung Pro Plus 512 GB.

Performances-wise, this card is quite capable. It has U3 and V30 ratings, indicating that it’s perfect for apps and games. Plus, you get maximum read speeds of up to 160 MB/s and write speeds of up to 120 MB/s. Impressive right? But what really sets this card apart is its massive 512 GB storage capacity. For a standard card, that’s an insane amount of space.

But if you want much lower storage, you can get the 128 GB and 256 GB versions too. The other features are pretty basic; you get the usual water and temperature resistance, shockproof design, and X-ray proofing. But the best part is that you can get it for around $67.99, which is quite affordable considering everything it offers.

How to Pick the Best MicroSD Cards For The Steam Deck: Step by Step

When choosing the best MicroSD card for the Steam Deck, these are the four things to consider:

  • Storage Capacity
  • Read/Write Speeds
  • Durability & Reliability
  • Price

Storage Capacity

Storage capacity is the most crucial factor when buying a MicroSD card. The Steam Deck can support cards up to 1 TB. That’s a lot of games, apps, and movies you can fit on one card. However, if your needs are more modest or you don’t have the budget for a 1 TB card, you can opt for lower storage options. But always ensure the card you choose has enough storage for your needs.

Read/Write Speeds

Read/write speeds are also significant when choosing a MicroSD card for the Steam Deck. Steam Deck supports apps and games that require fast loading speeds, so the card you choose should meet or exceed those expectations.

Check for the Class speeds your card should support – usually, it’s class 10 or higher. Read/write speeds can range from 50 MB/s to 200 MB/s, depending on the card. The faster the read/write speeds, the quicker your games and apps will load.

Durability & Reliability

Durability and reliability are key features to look out for when choosing a MicroSD card. You want to ensure that your data is safe and secure, especially if you’re using it to store games or other expensive applications. 

Look for cards with high-end components, such as shockproof and waterproof designs. Some Samsung cards are X-ray proof too, so they’re great if you travel a lot and need to protect your card from the rigors of airport security.


Finally, price. Always check the price before purchasing a MicroSD card. You can find great cards at reasonable prices, so take your time to shop around and get the best deal for your needs. Often cards with more features and higher storage capacities will cost more. But at the same time, you don’t want to skimp on quality for a lower price, either.

What to Know Before Buying a MicroSD card for the Steam Deck

Before you purchase a MicroSD card for the Steam Deck, there are a few things you need to know. First, ensure the card is compatible with the Steam Deck; some cards might not be. Secondly, you should check the maximum speed of the card; this is especially important if transferring large files.

Also, when it comes to capacity, consider the type of data you will be storing and select the capacity accordingly. Lastly, look for cards with a good warranty, as you never know when something might go wrong.

Using MicroSD Cards for the Steam Deck: What it’s Like

Using a MicroSD card on the Steam Deck is an ideal way to quickly expand your device’s storage capacity. The Steam Deck supports up to 1 TB of expandable storage, and these MicroSD cards can provide a great way to add extra game space. Most MicroSD cards offer fast read and write speeds, making them well-suited for gaming applications.

Plus, they come in various sizes, so you can find the perfect card to meet your needs. And thanks to their durable designs, you can rest assured that your data is safe and secure. All in all, MicroSD cards are an excellent way to expand the storage capacity of the Steam Deck.
