microSD card prices
A microSD card is a fingernail-sized removable flash storage card used to add or expand storage in handhelds, laptops, cameras, and other devices. It's an easy way to carry games, photos, music, and files without opening your device. Before you buy, check three things: the form factor (microSD, microSDHC, microSDXC, or microSDUC), the speed class your device expects, and the maximum capacity the device supports. Our catalog lists 21 devices with a microSD card slot, including the Valve Steam Deck, Nintendo Switch, and Dell Latitude 5420.

Before you buy
- Check the maximum capacity your device supports before choosing between 256 GB, 512 GB, and 1 TB. Every card on this page shares the same physical shape, but a device can still stop at a lower capacity than the largest card you can find. The specification sheet or manual lists the supported limit, and it's worth confirming before you order.
- Match the speed markings to what you actually do. U1/U3 and V10/V30/V60/V90 describe minimum sustained write speeds, which matter most for recording video or saving large game installs. A1/A2 describe how the card handles lots of small files, which matters if the card will store apps. Faster isn't always necessary, but a card that's too slow can hold up loading and saving.
- Plan for how the card will be used and cared for. Format the card in the device itself rather than on a computer so it uses the file system the device expects. If you'll swap the card between devices or copy files often, a card reader helps. Keep a copy of anything irreplaceable somewhere else, since any storage device can fail.
Questions
How do I know a microSD card will fit and work in my device?
Physically, almost every card on this page looks the same: all sizes of microSD card share one form factor, so a 1 TB card fits the same slot as a 256 GB card. The real question is support. Check the microSD format your device lists (microSDHC, microSDXC, or microSDUC), its capacity limit, and its required speed class. Our catalog shows 21 devices with a microSD slot, including the Valve Steam Deck, Lenovo Legion Go, ASUS ROG Ally X, Nintendo Switch, Nintendo Switch 2, Dell Latitude 5420, ASUS ROG Ally (2023), Framework Laptop 13 (Intel 11th–13th Gen), Dell PowerEdge R240, and Dell PowerEdge R740 — but always confirm the details for your own unit.
What speed class do I need?
It depends on the job. Speed classes are minimums, so a higher class is guaranteed to at least that level of sustained write performance. U1 and V10 are fine for photos, documents, and music. U3 and V30 are the usual choice for video recording and game installs. V60 and V90 are aimed at high-bitrate video. A1 and A2 are separate ratings that describe handling lots of small files, which is what matters when a card holds apps. Check which markings your device recommends before deciding.
Is a used or refurbished microSD card worth buying?
Used cards are cheaper, but flash memory wears a little every time it's written to, and there's no simple way to see how much life is left in a card someone else used. If you go used, test it right away by copying a large amount of data across and checking that everything arrives intact, and be ready to return it if anything looks wrong. For anything you'd be upset to lose, a new card plus a backup elsewhere is the safer route.
How much capacity do I need — 256 GB, 512 GB, or 1 TB?
Think about what the card will hold and how often you'll offload it. 256 GB suits documents, photos, and a modest media or game library. 512 GB is comfortable if you install several large games or record a lot of video. 1 TB makes sense when you want a big library with you and rarely want to delete or move files. Also keep the price per gigabyte in mind, and remember that larger cards give you room to grow — as long as your device supports the capacity.
