How to Choose a Steam Deck SD Card
There are various types of microSD cards for Steam Deck in the market and they have different features. To choose the best microSD card for Steam Deck, here’re some aspects you should take into consideration.
SD Card Speed Classes, Sizes and Capacities - All You Should Know
SD Card Types
The first thing to consider while choosing the best Steam Deck SD card is finding out the SD card types the Steam Deck requires. According to Valve, the Steam Deck SD card slot can be used to insert a microSD card, microSDHC card, or microSDXC card. The storage capacity of each SD card type is listed as follows:
- microSD: 2GB and under
- microSDHC: More than 2GB, up to 32GB
- microSDXC: More than 32GB, up to 2TB
To install as many games as possible, you’d better choose a microSDXC card with 2TB of storage capacity at most.

SD Card Speed Classes
When choosing the best SD card for Steam Deck, another essential factor is the SD card Speed Classes. The following are four basic ratings of the SD card Speed Class that may change the game installation speed:
- C2 (Class 2): Supports a minimum write speed of 2MB/s
- C4 (Class 4): Supports a minimum write speed of 4MB/s
- C6 (Class 6): Supports a minimum write speed of 6MB/s
- C10 (Class 10): Supports a minimum write speed of 10MB/s
As shown above, C2 is the slowest speed class while C10 owns the highest write speed. Therefore, to speed up the installation of games and make sure you can run games smoothly, it’s recommended that you choose C10.
Apart from the above speed class, the UHS (Ultra-High Speed) Speed Class that indicates the theoretical maximum read and write speeds is also important. There are two grades:
- U1 (UHS Speed Class 1): Supports a minimum write speed of 10MB/s
- U3 (UHS Speed Class 3): Supports a minimum write speed of 30MB/s
Although U3 is the better one, Steam Deck is only compatible with U1 currently. So, you can just choose U1.

Additionally, there is another type of Speed Class rating that is known as video speed classes (from V6 to V90). It’s an important factor to check for a camera SD card. But for your Steam Deck, the best choice is V30. It’s enough to shoot 4K videos and doesn’t cost much.
Reminder: As you can know above, Steam Deck only supports UHS-1 SD cards, which means it is limited to 100MB/S read speed. Therefore, the SD card you select doesn’t need to run faster than 100MB/S.
SD Card Storage Capacity
After ensuring what kind of SD card to choose and which speed class you need, you ought to consider the best storage capacity of the SD card for Steam Deck. That totally depends on how much space you need on your Steam Deck.
However, in case you meet the insufficient Steam Deck storage space issue in the future, it’s best to choose the largest SD card you can afford.
