512GB microSDXC card for action cameras and phones

This Lexar High-Performance 633x microSDXC card delivers 512GB of storage for smartphones, tablets and action cameras. It carries UHS-I, U3, Class 10, A2 and V30 ratings with read speeds up to 100MB/s and write speeds up to 70MB/s. The card records 1080p full-HD, 3D and 4K video without dropping frames.

Ideal for mobile creators needing app performance

The A2 rating lets the card run apps and games directly on Android devices, while V30 sustains the write throughput required for 4K video. Buyers who need sustained write speeds above 70MB/s or capacities beyond 512GB should consider other options. It is not suited for professional cinema workflows demanding higher bitrates.

SD adapter enables quick offload to laptops

An SD adapter is included so the microSD card fits full-size SD slots on laptops, card readers and cameras. This allows fast file transfers at up to 100MB/s without a dedicated microSD slot. No extra software or cables are bundled with the card.

Questions about this item

Does my device need a microSDXC slot and UHS-I support to use this 512GB card?

Yes, the host must accept microSDXC cards and UHS-I speeds to reach the rated 100MB/s read and 70MB/s write performance.

Will this card work in an older camera that only supports Class 10 speeds?

It is backward compatible with Class 10 devices, though speeds will be limited to that device's maximum capability.

How can I confirm the card is delivering its rated V30 and A2 performance after setup?

Run a benchmark tool to verify sustained write speeds of at least 30MB/s and check that apps launch smoothly from the card.
