A host interface module is operable to couple the disk drive to a host device. The host interface module includes a plurality of personality modules, each of the plurality of personality modules, when coupled to the host device, is operable to accept read and write commands and transfer data to and from the host device in a corresponding one of a plurality of host interface protocols. A universal host module decodes read and write commands from the host device and transports data written to and read from the disk drive via a first of the plurality of personality modules. A multiplexer selectively couples the first of the plurality of personality modules to the universal host module in response to a selection signal. A system interface couples the universal host module to a processor and a memory of the disk controller.
