64GB microSDXC for Android phones

The SanDisk Ultra microSDXC card provides 64GB of storage for Android smartphones and tablets. Its A1 rating means apps launch faster and run more smoothly directly from the card. Class 10 speed supports Full HD video recording and high-quality photos. The UHS-I interface works with a wide range of mobile devices.

Class 10 UHS-I reliability

Class 10 certification guarantees a minimum sustained write speed for uninterrupted Full HD capture. The UHS-I bus enables read speeds up to 100MB/s for quick file offloading. The compact microSD form factor fits flush inside phone trays or tablet slots. No moving parts mean silent operation and resistance to everyday shocks.

SD adapter included for flexibility

A standard SD adapter is bundled so the card can be read by laptop slots or desktop card readers. This lets you transfer up to 1200 photos per minute to a computer without a separate USB dongle. The adapter also makes the card compatible with cameras that only accept full-size SD media.
