Chromebook-Ready microSDXC Card

The SanDisk Ultra microSDXC 128GB card carries UHS-I, U1, Class 10 and A1 ratings. It is tested and certified to work seamlessly with Chromebooks, making it a straightforward storage upgrade for those devices. Read speeds reach up to 120MB/s for moving photos and files quickly. The A1 rating helps Android apps launch and run faster on compatible hardware.

For Chromebook Users and Basic Media

This card suits Chromebook owners who need more space for documents, photos and Full HD video playback. Android app performance benefits from the A1 classification. Buyers who require sustained write speeds beyond the U1 minimum for high-bitrate recording workflows should look at a different card class. The 128GB capacity also limits users building large local media libraries.

UHS-I U1 Speed Class Decides Fit

The single specification that determines suitability is the UHS-I U1 speed class, which guarantees a minimum sequential write of 10MB/s. This supports Full HD video recording and smooth app operation but does not meet the demands of 4K capture or professional burst photography. Match this rating to your device requirements before purchasing.
