512 GB microSDXC card for cameras and phones

This ADATA Premier Pro microSDXC card provides 512 GB of storage for devices that accept the microSDXC form factor. It carries UHS-I U3, Class 10, V30 and A2 ratings, so it supports Full HD 1080p and Ultra HD 4K video capture as well as faster app loading. The card includes an SD adapter for use in full-size slots.

Replaces slower or smaller microSD cards

If your current card cannot sustain 30 MB/s write speeds or lacks the A2 rating for app performance, this model removes those bottlenecks. The jump is worth it when you record 4K footage continuously, run apps directly from the card, or need the 512 GB capacity for extended sessions without offloading.

Check device compatibility and speed requirements

Verify that your device supports microSDXC cards up to 512 GB and can use the UHS-I interface. Confirm it requires at least V30 or Class 10 for your recording mode. The card operates from -25 to 85 °C and meets IPX7 waterproof, shockproof, X-ray proof and magnet-proof standards for harsh environments.

Questions about this item

Does the 512GB microSDXC card include an SD adapter for full-size slots?

The card ships with an SD adapter so it can be used in full-size SD slots on cameras, laptops or card readers.

What file system should I format the card to before first use in a dash recorder?

Format the card as exFAT in the recorder or on a PC; exFAT supports the 512GB capacity and the sustained 30MB/s V30 write speed required for 4K recording.

How often should I run a full error-scan on the card used for daily in-car recording?

Run a full scan every few months or after any crash; the card includes automatic ECC, but periodic checks catch early wear from constant overwrite cycles.
