128GB microSDXC card for Android devices

The SanDisk Ultra microSDXC card delivers 128GB of storage with read speeds up to 140 MB/s. Its Class 10 rating supports Full HD video recording and the A1 specification enables faster app loading on compatible smartphones and tablets.

Ideal for expanding phone storage and media capture

This card suits Android users who want more space for photos, videos, music and apps with quicker launch times. It is not suited for buyers who require higher sustained write performance for 4K recording or professional camera workflows.

Class 10 and A1 ratings define the use case

The Class 10 speed class guarantees minimum write performance for Full HD video while the A1 rating certifies random read and write speeds for app operations. These two specifications determine whether the card matches your device and workload requirements.

Questions about this item

Does my phone need a microSDXC slot to use this 128GB card?

Yes, the host device must support the microSDXC standard to recognise the full 128GB capacity.

Will this card work in a device that only reads Class 4 cards?

The card is rated Class 10 and will operate at the host's maximum supported speed, so it functions in older slots but at their lower rate.

How can I confirm the card is delivering its rated 140MB/s read speed?

Run a benchmark tool such as CrystalDiskMark or the SanDisk Memory Zone app; sequential read results should approach 140 MB/s on a UHS-I interface.
