US Patent 7783854 System and method for expandable non-volatile storage devices

A method and system is introduced to allow expanding the storage capacity of a storage device using other storage device units in a dynamic manner. The expanded device may emulate a single large capacity media device. Files existing on device prior to device expansion may remain valid following device expansion. Capacity of storage devices and digital appliances making use of storage devices may be expanded. Instead of replacing a device with a larger capacity device, storage capacity can be expanded. The device may allow implementing file access policies to protected files.
