A miniature mobile storage device is an umbrella term for any small data storage device that can connect to your computer and retain information. Universal Serial Bus drives, Secure Digital cards and even cellular phones are examples of miniature mobile storage devices.
Since the beginning of computer technology, there have been many iterations of miniature storage devices. In the past, floppy disks could only contain 1,110 kilobytes, but now USB thumb drives that can hold one terabyte in data are available to consumers.
The most common way to connect miniature mobile storage devices to a computer is the universal serial bus port on a computer. These ports were designed to transfer data, supply power and add peripheral controllers to the computer setup.
