Will this card record 4K video?

The U3 and V30 ratings are the classes cameras ask for when recording 4K. Real sustained write speed can fall below the 70 MB/s claim, so test the card before relying on it for long takes.

Is 512GB enough for a Switch or phone?

Yes for most people. 512GB holds a large game library or thousands of photos and hours of video, and microSD is the format both devices accept.

How do I check it is really 512GB?

Run a free capacity test such as H2testw or f3 on a computer. Unbranded high-capacity cards are sometimes programmed to report more space than they hold, and the test exposes that.

Does it work in a dash cam or security camera?

It fits, and the temperature range covers most climates. Continuous recording wears cards quickly, and this one publishes no endurance rating, so check it periodically.

The card itself. A full-size SD adapter is not listed, so buy one separately if you need to use it in an SD slot.

Our take on the 512GB SD Memory Card Flash TF Class 10

This is a 512GB microSD card rated Class 10, U3 and V30, with claimed read speeds up to 100 MB/s and write speeds up to 70 MB/s. Those ratings make it suitable for 4K video recording in phones, action cameras and drones, and for expanding storage in a Switch or tablet. It is a generic, unbranded card, so the headline numbers are claims rather than independently verified figures. Branded rivals from SanDisk, Samsung and Lexar publish tested speeds and back them with longer warranties, which matters most for large sustained writes.
