Disclosed is a method and apparatus for a storage system comprising at least one mobile random access storage device capable of storing first or second data. At least one docking station is associated with an address wherein the address is identifiable by at least one host computer. A first and second sub-address is associated with the at least one docking station wherein the first and second sub-addresses are identifiable by the at least one host computer. The first sub-address corresponds to a first virtual device adapted for storing the first data on a first virtual media. The second sub-address corresponds to a second virtual device adapted for storing the second data on a second virtual media wherein the second virtual media is a different media type from the first virtual media. The at least one docking station is adapted to be responsive to the at least one host computer as available for storing the first data at the first sub-address or the second data at the second sub-address when the at least one docking station is operatively linked with the at least one mobile random access storage device.
