Cheapest 256 GB microSD card
A 256 GB microSD card is a small removable flash card that adds storage to handhelds, laptops, cameras, and phones. You'll use it for games, photos, video, and apps. Before buying, check three things: the form factor (microSD, not full-size SD), the interface and speed class your device supports, and compatibility — some devices cap capacity or need a specific file format. Our comparison also covers 512 GB and 1 TB cards, plus 11 devices in our catalog that accept one.

Before you buy
- Match the speed class to what you'll do with it. For recording video or loading games, look at the sustained write rating (V30 or higher is a common baseline). If you plan to run apps directly from the card, the A2 application class rating matters more than the headline read speed.
- Check the maximum capacity your device supports before going bigger. A card that physically fits can still be rejected or limited if the device's hardware or firmware caps the size or expects a particular file format such as exFAT.
- Compare sustained write speeds, not just the big read speed on the box. Manufacturers usually quote their fastest read figure; write speed is what you feel when saving large files, recording footage, or installing games. Cards also vary in warranty length, so that's worth weighing too.
Questions
Will a 256 GB microSD card fit my device?
Physically, yes — a microSD card is the same small size regardless of capacity, so a 256 GB card fits any microSD slot. The question is whether your device supports that capacity and format. Our catalog lists 11 devices that accept one, including the Valve Steam Deck, Lenovo Legion Go, ASUS ROG Ally X, ASUS ROG Ally (2023), Nintendo Switch, Nintendo Switch 2, Framework Laptop 13 (Intel 11th–13th Gen), Dell Latitude 5420, Dell Latitude 5430 (Intel 12th Gen), and Dell Latitude 5530 (Intel 12th Gen). Check your manual for the supported maximum.
How fast does a microSD card need to be?
It depends on the job. For storing documents, photos, and music, almost any current card is fine. Recording video and loading games want a sustained write speed — V30 or above is a common starting point. Running apps or moving lots of small files benefits from the A2 application class. If two cards look similar, compare sustained write ratings rather than the peak read speed printed on the label.
Can I buy a used or refurbished microSD card?
You can, but flash memory wears out with each write, and you can't see that wear from the outside. If you go used, test the card before trusting it: copy a large file back and forth and verify the contents match, and check that the full capacity is actually readable. Anything that fails to copy cleanly, shows less capacity than advertised, or behaves erratically should be avoided.
Is 256 GB enough storage?
For most people, 256 GB covers a solid mix of apps, games, and media. It fills faster if you keep large game installs or record long video directly to the card. Think about what you'll store and leave some headroom — cards run slower and are harder to manage when nearly full. If you regularly juggle big installs or video projects, compare the 512 GB and 1 TB sizes alongside it before deciding.
