Abstract:
A cache control method for a hybrid hard disk drive (HDD) comprising a nonvolatile cache (NVC) and a hard disk. When the hybrid HDD is operating in a non-parallel mode of operation, the control method sequentially searches the NVC and then reads the hard disk for requested data, but when the hybrid HDD is operating in a parallel mode of operation, the control method simultaneously searches the NVC and reads hard disk for the data requested.
