Our take on the Samsung Pro Plus 512GB MicroSD Card
The Samsung Pro Plus is a UHS-I microSD card aimed at action cameras, drones, phones and handheld consoles that need fast, durable storage. Its 512GB capacity holds hours of 4K video or a large game library. It is rated for high read speeds and comes with a full-size SD adapter. Against UHS-II cards it is slower on paper, but it costs far less and works in almost any device. Owners rate it as dependable, though sustained write speeds drop during long recordings.

- Rated for water, temperature, X-ray and magnet resistance
- Includes a full-size SD adapter

- Yes. It fits both, and the 512GB capacity holds a large game library. Both devices run it at UHS-I speeds.
