512GB microSD for action capture

The SanDisk Extreme microSD UHS-I card delivers 512GB capacity with read speeds up to 245MB/s and write speeds up to 170MB/s. It carries A2, U3 and V30 ratings for sustained performance. The card targets enthusiasts and creators using action cameras, drones and Android devices.

Suits 5K and 4K UHD workflows

Users recording 5.3K point-of-view footage or 4K UHD aerial video will benefit from the V30 guarantee. The A2 rating helps apps load quickly on Android devices and handheld consoles. Buyers who need more storage or faster sustained write speeds for professional cinema workflows should look elsewhere.

512GB capacity with V30 headroom

The 512GB space accommodates long 5K and 4K UHD recording sessions plus high-resolution still bursts. V30 ensures a minimum 30MB/s sequential write for smooth capture. The ceiling appears when projects demand higher sustained write throughput or larger capacities than 512GB.

Questions about this item

What device slot is needed to use this 512GB microSD card?

A microSDXC slot that supports UHS-I is required for the card to operate at its rated speeds.

Will this card work in an older camera that only accepts UHS-I U1 cards?

Yes, the card is backward compatible with UHS-I U1 devices, but write speeds will be limited to the host's maximum capability.

How can I confirm the card is delivering the rated 245MB/s read and 170MB/s write speeds after setup?

Run a benchmark tool such as CrystalDiskMark on a UHS-I reader; sequential results should approach 245MB/s read and 170MB/s write.
