512GB microSDXC card for 4K capture

This Gigastone microSDXC card delivers 512GB of storage with UHS-I U3 and V30 ratings. Sequential read speeds reach 100MB/s and write speeds reach 60MB/s. The A2 class supports faster app loading on smartphones and tablets. It is built for 4K video recording and gaming on compatible devices.

Action cameras, drones and handheld consoles

The card suits creators using GoPro, DJI drones or Nintendo Switch who need sustained 4K write performance. It also expands storage for Android phones, tablets, laptops and dash cams. Devices limited to the microSDHC standard cannot accept this 512GB capacity. Users who require UHS-II or V60 speeds for higher-bitrate workflows should consider other options.

U3 V30 sustained write guarantee

The V30 rating guarantees a minimum sequential write speed of 30MB/s, which is the spec that ensures uninterrupted 4K recording. U3 provides the same 30MB/s floor for UHS-I devices. If your workflow demands a higher guaranteed minimum, this card does not meet it.
