Cheapest 512 GB microSD card
A 512 GB microSD card is a small removable flash memory card that adds storage to any device with a microSD slot—handheld gaming systems, laptops, tablets, and cameras. It's an easy way to make room for games, apps, photos, and video. Before you buy, check three things: the form factor (microSD, not full-size SD), the speed class your device requires, and whether your exact model lists microSD support. Our catalog currently shows 11 devices that accept this card.

Fits these devices
Before you buy
- Check the slot, not just the label. A full-size SD card will not fit a microSD slot, and some laptops offer only a full-size SD slot that needs a separate adapter. Look up the slot type for your specific model before you order.
- Match the speed rating to what you'll do with the card. For recording video or running apps and games from the card, look for higher sustained write ratings (such as V30 or U3) and, for app use, A1 or A2 ratings. Slower, less expensive cards are fine for storing documents, music, and photos you only read back.
- Compare capacities side by side. Our pages show 256 GB, 512 GB and 1 TB options together, so you can see whether stepping up a size makes sense for how much you store. If your device documents a maximum supported capacity, stay within that limit.
Questions
Will a 512 GB microSD card fit and work in my device?
If your device has a microSD slot, a 512 GB card will physically fit. Whether it works at that capacity depends on the device—some models publish a maximum supported size, and some older ones don't handle the largest cards well. Our compatibility list shows devices in our catalog that accept microSD; check your model's specifications to confirm the supported capacity.
How fast does a microSD card need to be?
It depends on your use. For file storage and photo backups, most cards are quick enough. For recording video or launching apps and games from the card, look at the sustained write rating (V30, V60, and so on) and, for apps, the A1/A2 ratings. Note that real-world speed also depends on your device's card reader.
Is it safe to buy a used microSD card?
A used card can work, but you have less information about how much wear it has had and how well it has been kept. If you buy used, test it right away by filling it with data and reading it back, and check that the reported capacity matches what you paid for. New cards usually include a warranty, which is worth weighing against the savings.
How much microSD capacity do I actually need?
Count what you plan to store: large game installs and video files add up fastest, while documents, music, and photos use much less space. If you keep only a small library, 256 GB is often plenty. A 512 GB card is a comfortable middle ground, and 1 TB suits anyone with a large game or media collection. Our size comparison pages let you weigh the options.
