For an Android tablet, I purchased this to expand its storage capacity. I purchased Lexar based on its reputation as the greatest high-speed memory device for DSLR cameras. The tablet immediately identified the memory card and asked whether I wanted to format the card and use it just for storage, or if I wanted to use it for both storage and applications. I chose the second option. I decided to go with applications and cloud storage. The tablet's system memory has increased from 32 gigabytes to 64 gigabytes, according to the tablet's settings. Simply perfect.
