ABSTRACT:
A write medium is selected so as to realize the fastest operation after data including a write command has been received from the host device. A storage device comprises a host interface, a cache memory interface, a hard disk interface, a flash memory interface, a command analyzing section which analyzes the contents of a command inputted from the host interface, a state determining section which determines into which of the cache memory and flash memory data can be written faster based on the relationship between the write data size and the free space of the cache memory if the command analyzed in the command analyzing section is a write command, and a media selecting section which determines a data write destination according to the determination result of the state determining section.
