SanDisk Extreme Go microSDXC 256GB

The SanDisk Extreme Go microSDXC card delivers 256GB of storage for Android devices, action cameras and drones. It carries UHS-I U3, V30 and A2 ratings so apps load quickly and 4K video records without dropped frames. The card is built with NAND flash for long-term reliability.

UHS-I U3 V30 A2 speed class

The decisive specification is the UHS-I U3, V30 and A2 rating combination. It guarantees a minimum sustained write speed of 30MB/s for 4K capture and meets the A2 standard for faster app performance on Android. Devices that require UHS-II or higher bus speeds will not benefit from the card's maximum throughput.

Durability and operating conditions

The card is waterproof, humidity proof, shock proof, X-ray proof and magnet proof. These protections keep data safe during outdoor shoots, travel and security screening. No active cooling is involved so the card runs silently and draws minimal power from the host device.

商品問答

What does the 240MB/s read speed mean when the card is inside my device?

The 240MB/s figure is the maximum sequential read speed the card can deliver on a UHS-I host; real-world throughput depends on the device controller and file system overhead.

What does the UHS-I U3 V30 A2 rating tell me about the interface and its practical limits?

UHS-I is the bus standard; U3 and V30 both guarantee a minimum sustained write of 30MB/s for 4K video, while A2 certifies faster app loading on Android.

What do I need to check so the card physically fits and mounts in my gear?

The card is a microSDXC form factor, so it fits any slot that accepts microSDXC or microSDHC; an SD adapter is required for full-size SD slots.
