512 GB microSDXC card for Android devices

This ADATA Premier microSDXC card delivers 512 GB of storage for smartphones and tablets. It carries an A1 rating so Android users can install and run apps directly from the card. Read speeds reach up to 100 MB/s and the bundled full-size SD adapter lets you transfer files to a laptop or camera without extra hardware.

UHS-I Class 10 practical limits

The UHS-I interface caps sequential reads at the rated 100 MB/s and sustained writes at the Class 10 minimum of 10 MB/s. Real-world throughput will drop below those peaks when the host device or card reader cannot maintain the bus clock, so large video files may copy more slowly than the headline figure suggests.

Simple install with one common snag

Insert the microSD card into the phone or tablet slot, then format it as portable or adoptable storage in the OS settings. The included SD adapter fits any full-size slot for desktop access. The most frequent issue is a device that only supports cards up to a lower capacity, which will refuse to mount the 512 GB volume.
