Abstract: A hybrid storage device comprises at least one storage disk, a disk controller configured to control writing of data to and reading of data from the storage disk, a non-volatile electronic memory, and a bridge device coupled between the disk controller and the non-volatile electronic memory. The disk controller comprises a plurality of high-speed serial interfaces. In one embodiment, the high-speed serial interfaces include a first high-speed serial interface configured to interface the disk controller to a host device, and a second high-speed serial interface configured to interface the disk controller to the non-volatile memory via the bridge device. The non-volatile memory may comprise a flash memory, and the bridge device may comprise a flash controller. The disk controller may be implemented in the form of an SOC integrated circuit that is operative in a plurality of modes including a hybrid mode of operation and an enterprise mode of operation.
