ADATA Premier 512GB microSDXC Card

This ADATA Premier microSDXC card delivers 512GB of storage with UHS-I Class 10 performance. It reaches read speeds up to 100MB/s and write speeds up to 25MB/s. The card carries A1 and V10 ratings for app loading and sustained video capture. An SD adapter is included for broader device compatibility.

Suits phones, tablets, drones and action cameras

The A1 rating helps installed applications launch and run smoothly on mobile devices. V10 certification guarantees a minimum 10MB/s write stream for Full HD 1080P recording. Users needing faster sustained write speeds for higher-bitrate formats or 4K capture should look at cards with higher video speed class ratings.

UHS-I Class 10 with A1 and V10 ratings

The combined Class 10, U1, A1 and V10 markings define the card's guaranteed minimum performance tier. Read speeds up to 100MB/s accelerate file offloads to a computer. Write speeds up to 25MB/s handle typical photo bursts and Full HD video. This specification set determines whether the card matches a device's required speed class.

Questions about this item

What device slot do I need for this 512GB microSDXC card to work?

You need a microSDXC-compatible slot; devices that only support microSDHC cannot address the 512GB capacity.

Will the included SD adapter let me use this card in an older camera that only takes full-size SD cards?

Yes, the bundled adapter converts the microSDXC card to full-size SD so it fits legacy cameras, provided the camera supports SDXC capacities.

How can I verify the card is delivering its rated 100MB/s read speed after setup?

Run a sequential read benchmark such as CrystalDiskMark or Blackmagic Disk Speed Test on a UHS-I reader and confirm results approach 100MB/s.
