Ready for Chromebook and Android

The SanDisk Ultra microSDXC card offers 256GB of storage and is tested and certified to work seamlessly with Chromebooks. Its A1 rating means Android apps launch faster and run more smoothly. Class 10 performance supports Full HD video recording and playback directly from the card. Read speeds reach 150MB/s for quick file transfers.

Check your device slot and speed needs

Verify that your phone, tablet, Chromebook or other host accepts microSDXC cards before ordering. The card uses the UHS-I interface, so maximum read speed of 150MB/s requires a compatible UHS-I reader or slot. Write speed is below 150MB/s, which may limit burst photography or high-bitrate video capture. Ensure your device can make use of the A1 application performance class.

Durable build with everyday protection

The card is waterproof, temperature-proof and X-ray-proof, so it survives spills, airport scanners and extreme climates. Its compact microSD form factor fits flush in most slots without protruding. No adapter is mentioned in the specifications, so plan for a microSD-to-SD adapter if your reader only takes full-size cards. The rugged construction suits daily mobile use.
