Hybrid hard disk drive having a flash storage processor

摘要

An apparatus is described that is configured to control operations in a hybrid hard disk drive. In an implementation, the apparatus includes a hybrid flash storage processor connected to the host interface that is configured to communicatively couple a flash storage component and to a hard disk integrated circuit chip. The integrated circuit chip includes a read/write channel device configured to communicatively couple to a hard disk drive assembly and a hard disk drive controller operatively coupled to the read/write channel device. The hard disk drive controller is configured to operate the read/write channel device to store and to retrieve data on the hard disk drive assembly. The flash storage processor is configured to furnish a command to the integrated circuit chip when the command represents an instruction for accessing the hard disk drive assembly and is configured to access the flash storage component when the command represents an instruction for accessing the flash storage component.
