Capacity and Use Cases

This SanDisk Ultra microSDXC card provides 128GB of storage for Android smartphones, tablets, cameras, drones and Nintendo Switch consoles. The included SD adapter extends compatibility to full-size SD slots in laptops and card readers. It is rated A1 for faster app loading and Class 10 for Full HD video recording.

Speed and Interface Limits

The card uses a UHS-I interface with a maximum read speed of 120MB/s, allowing rapid transfer of up to 1000 photos per minute. Write speeds are lower than the quoted read figure, so sustained burst shooting or large file writes will not reach the peak rate. The A1 rating guarantees minimum random read and write performance for applications, not sequential throughput.

Compatibility Checks

Verify that your device supports the microSDXC standard and the UHS-I bus to achieve the stated speeds; older hardware limited to microSDHC will not recognise the 128GB capacity. Confirm the host has a microSD slot or use the supplied adapter for full-size SD slots. The SanDisk Memory Zone app for file management requires Android and the Google Play store.

Questions about this item

Which capacity should I pick — 16GB, 32GB, 64GB, 128GB or 512GB?

Choose the size that matches your storage needs; this listing is the 128GB model, while the same series also offers 16GB, 32GB, 64GB and 512GB options.

What does the 120MB/s read speed actually deliver in my phone or camera?

The 120MB/s figure is the maximum transfer rate for moving files off the card; real-world throughput depends on your device’s UHS-I implementation and file sizes.

How does the UHS-I interface affect performance?

The card uses a UHS-I bus, which supports the quoted 120MB/s read speed and guarantees at least 10MB/s sustained write for Full HD video capture.
