Best MicroSD Cards (2026)

What We Tested

We benchmarked nine microSD cards using CrystalDiskMark and real-world file transfers across phones, a Nintendo Switch, a Steam Deck, and a GoPro camera. We tested sequential read and write speeds, random 4K performance, and reliability over hundreds of insert-and-remove cycles.

MicroSD cards are commodity storage, but not all of them perform the same in every device.

Our Top Picks

Best Overall: Samsung EVO Select 256GB

The EVO Select is Samsung’s value-tier microSD, and it performs well above its price. You get consistent 130 MB/s reads, A2 app performance class for smooth phone storage expansion, and the kind of reliability Samsung is known for. The included full-size SD adapter is a nice touch for moving files to laptops and cameras.

Write speeds are slower than Samsung’s Pro Plus line, which matters if you are recording 4K video continuously. But for phones, tablets, and gaming handhelds, the EVO Select is the card to buy.

Best Value: SanDisk Ultra 256GB

SanDisk has been making flash storage longer than almost anyone, and the Ultra reflects that experience. Read speeds hit 150 MB/s, and the card works reliably across an enormous range of devices. The 10-year warranty gives you confidence the card will outlast the device it goes in.

The A1 app performance rating means it is slightly slower than A2 cards when running apps directly from the card. But for photo storage, music libraries, and general file transfer, the SanDisk Ultra is a safe, affordable choice.

Best for Gaming: Lexar PLAY 256GB

Lexar designed the PLAY card specifically for gaming handhelds, and it shows. A2 performance means games load quickly on Switch and Steam Deck, and 150 MB/s reads keep loading screens short. The card is validated for compatibility with the devices gamers actually use.

Lexar does not have the name recognition of Samsung or SanDisk, which makes some buyers hesitant. But in our benchmarks, the PLAY card matched or beat both competitors in gaming-specific workloads. If your primary use is a gaming handheld, the Lexar PLAY is the right pick.

Bottom Line

The Samsung EVO Select is the best all-around microSD card for the money. The SanDisk Ultra is the safe, proven budget choice. And the Lexar PLAY is purpose-built for gamers. At 256GB for under $20, all three are outstanding value — just match the card to your primary use case.
