SanDisk Extreme Go 128GB microSDXC

This SanDisk Extreme Go microSDXC card provides 128GB of removable storage for mobile devices and action cameras. It uses UHS-I U3 V30 A2 speed classes to sustain high-bitrate 4K video recording and fast app loading on Android. The card is built with durable NAND flash memory.

For 4K video and Android app performance

The U3 and V30 ratings guarantee minimum write speeds for uninterrupted 4K capture, while the A2 rating speeds up installed applications. Buyers who need higher capacities or faster sustained write speeds for professional video workflows should consider other options.

Up to 240MB/s read speed

The maximum read speed of 240MB/s allows quick offloading of large media files to a computer. Write speed reaches up to 120MB/s. This single figure determines if the card matches your device's bandwidth requirements and your post-production workflow pace.

Questions about this item

Does the SanDisk Extreme Go microSDXC 128GB card come with an adapter or reader in the box?

The card is sold as a single microSDXC unit; no SD adapter or USB reader is included and must be purchased separately if required.

Which speed rating on the Extreme Go 128GB card matters for 4K video recording?

The V30 rating guarantees a minimum sustained write speed of 30MB/s, which meets the requirement for 4K capture on compatible devices.

What does the 240MB/s read speed mean when the card is used in a phone or camera?

It is the maximum sequential read rate under ideal conditions; real-world transfer speeds will be lower and depend on the host device's UHS-I interface and workload.
