Abstract:
A storage device includes a drive selection section (1), a hard disk drive (HDD) (2), and a non-volatile memory drive (3). When an instruction such as a data I/O instruction is issued from a host such as a CPU (5) and an ATA controller (6) to the hard disk drive (HDD) (2), the drive selection section (1) receives the address value. If the address value is included in the address space predefined, the non-volatile memory drive (3) is made to execute the instruction. Otherwise, the hard disk drive (HDD) (2) is made to execute the instruction.
