A data storage device may comprise a controller, first and second host-addressable logical units and a communication interface. The first logical unit may comprise a first data storage, first endpoints associated with the first data storage and a first bus interface coupled between the first data storage and the first endpoints. The second logical unit may comprise a second data storage and second endpoints. The second endpoints may be associated with the second data storage and may be separate and distinct from the first endpoints. A second bus interface may be coupled between the second data storage and the second endpoints. The communication interface may be coupled to the first and second host-addressable logical units and may be configured according to communicate with the host according to a predetermined communication protocol.
