Best SD Card for Steam Deck: the SanDisk Extreme microSD card against a white background

1. SanDisk Extreme microSDXC

Naturally, the best microSD card for Steam Deck should be as big as possible without sacrificing its read speeds – no disrespect to loading screen tips, but we’d rather be playing the game. The SanDisk Extreme microSDXC 1TB model can’t hit its 160MB/s read speed ceiling because of the Steam Deck’s own limitations, but it still performs better than its competition with heights of 100MB/s. This is the sweet spot with the Steam Deck’s own limitations in mind.

Western Digital claims that the SanDisk Extreme microSDXC card is waterproof, shockproof, and even x-ray proof. We don’t recommend putting any of those claims to the test, but it also comes with a lifetime warranty if you do, which is more than most alternatives. If 1TB is a bit too rich for your taste, it also comes in 512GB, 400GB, 256GB, 128GB, 64GB, and 32GB flavors, although you might struggle with anything in double-digit territory.

Best SD Card for Steam Deck: the Samsung EVO Plus microSD card against a white background

2. Samsung EVO Plus or EVO Select

The Samsung EVO Plus and EVO Select are virtually identical. Amazon has exclusive rights to the Select in some countries, but with the same speeds, classifications, and warranties, it’s worth shopping around for the cheapest one available. Better yet, they’re sometimes available in multi-packs.

The write speeds are slightly slower than SanDisk’s alternative but read speeds contend with the best at 100MB/s. This is plenty for running indie games on the Steam Deck without a hitch.

Best SD Card for Steam Deck: the Lexar Play microSD card against a white background

3. Lexar Play

You’ll save the most money by dropping to a 512GB, 256GB, or even a 128GB model, but the Lexar Play is often the cheapest 1TB microSD card for the Steam Deck on the market thanks to its high sales. It’s designed more with smartphones and the Nintendo Switch in mind, but it’s more than up to the job of running your Steam library without issue.
