A storage controller for a host device comprises a control module that receives data storing and data retrieving requests from the host device. A disk drive that is controlled by the control module and that selectively stores user data received from the control module and selectively retrieves the user data for the control module. Non-volatile semiconductor memory is controlled by the control module and selectively stores user data received from the control module and selectively retrieves the user data for the control module. The control module selects at least one of the disk drive and the non-volatile semiconductor memory for storage and retrieval of the user data.
