SanDisk SanDisk Ultra 128GB SDXC UHS-I Class 10 U1 Up to 140MB/s Read Memory Card
The SanDisk Ultra 128GB is a SDXC memory card using the UHS-I interface. This exact SKU carries the Class 10 U1 ratings.

The combination of capacity, format, interface and confirmed class markings is what distinguishes this exact model from neighbouring capacities and earlier or later revisions.The specification deliberately separates read speed, write speed and class markings because each describes a different aspect of card performance.
