SanDisk Extreme Go microSDXC 64GB

The SanDisk Extreme Go microSDXC card delivers 64GB of storage for action cameras, drones and Android devices. It carries UHS-I U3, V30 and A2 ratings for sustained 4K video capture and fast app loading. Read speeds reach up to 170MB/s while write speeds hit up to 80MB/s. The card uses NAND flash technology built for durability.

Upgrading from slower microSD cards

This card replaces older microSDHC or basic microSDXC cards that lack U3 or V30 ratings and cannot sustain 4K recording. The jump is worth it when your device demands minimum write speeds of 30MB/s for high-bitrate video or quicker app performance. Cards without A2 classification will not match the random read and write responsiveness shown here. Buyers who need capacities beyond 64GB should consider larger options.

Check your device compatibility

Verify that your host device supports the microSDXC standard and UHS-I speeds before ordering. Confirm the card slot accepts the microSD form factor and that firmware can handle the stated speed classes. Some older hardware may limit performance to lower speed tiers. The card is waterproof, humidity proof, shock proof, X-ray proof and magnet proof for rugged use.

Questions about this item

What device slot does the microSDXC card fit into?

It fits any microSDXC or microSDHC slot that accepts UHS-I cards, such as Android phones, action cameras, drones or a USB card reader.

How do I install the card and what step is often missed?

Power off the host device, insert the card label-side up until it clicks, then format it in the device settings before first use — skipping the format is the common mistake.

When should I replace the card and how do I know?

Replace it if write errors appear, capacity drops below 64GB, or after heavy 4K recording cycles; the NAND flash is rated for durability but not infinite writes.
