512GB MicroSDXC for Gaming and 4K Video

The Gigastone Game Turbo card delivers 512GB of storage in the microSDXC form factor. It targets Nintendo Switch owners, action-camera users and smartphone photographers who need capacity for large game libraries or extended 4K recording sessions. The A2 rating means installed applications launch and run more responsively on Android devices.

UHS-I U3 V30 Durability and Compatibility

Built to UHS-I with U3 and V30 speed grades, the card sustains the write throughput required for uninterrupted Ultra HD video. It is rated waterproof, shockproof, temperature-proof and X-ray proof, so it survives the rough handling common in drones, dash cams and handheld consoles. The microSD form factor fits directly into Switch, GoPro, DJI and Android slots without adapters.

Sequential Read Up to 100MB/s Write Up to 60MB/s

The single specification that decides suitability is the rated sequential performance: read up to 100MB/s and write up to 60MB/s. That write ceiling meets the V30 guarantee for 4K capture but falls short of sustained bitrates demanded by professional cinema codecs. Buyers who need faster sustained write speeds for high-bitrate 4K or 8K workflows should look elsewhere.
