512GB microSDXC for Android & action cameras

The SanDisk Extreme Go microSDXC card delivers 512GB of storage with UHS-I U3, V30 and A2 ratings. Read speeds reach up to 240MB/s and write speeds up to 160MB/s. It is built for 4K video capture and fast app loading on Android devices.

Simple slot insertion with rugged protection

Installing the card only requires placing it into a compatible microSDXC slot. The card uses NAND flash technology and is waterproof, humidity proof, shock proof, X-ray proof and magnet proof. The most common issue is using a device limited to UHS-I speeds below the card's maximum capability.

Verify host device supports microSDXC and UHS-I

Before ordering, confirm your device accepts microSDXC cards up to 512GB and supports the UHS-I interface. Check that the host can utilise U3 and V30 speed classes for 4K recording. Devices limited to microSDHC or lower speed classes will not fully benefit.

Questions about this item

How can I verify the card is delivering the rated 240MB/s read and 160MB/s write speeds after setup?

Run a benchmark tool such as CrystalDiskMark or AJA System Test on a PC with a UHS-I card reader; sequential results should approach 240MB/s read and 160MB/s write.

What is included in the box and do I need to buy a reader or adapter separately?

The package contains the 512GB microSDXC card only; a microSD-to-SD adapter or USB card reader must be purchased separately if your device lacks a microSD slot.

Which speed-class version should I choose for 4K video and app performance on Android?

This model carries UHS-I U3, V30 and A2 ratings, making it suitable for 4K capture and fast app loading on Android devices.
