NONVOLATILE STORAGE DEVICE, ACCESS DEVICE, AND NONVOLATILE STORAGE SYSTEM

摘要

An access device (100) includes an access speed reporting unit (112) for reporting an access speed required for data recording by the access device (100) to a nonvolatile storage device (200). The nonvolatile storage device includes an access condition decision unit (212) for deciding an access condition required for satisfying the reported access speed and an access region decision unit (213) for deciding an access region according to the decided access condition. The access device (100) reports the required access speed to the nonvolatile storage device (200) in advance so that the access condition decision unit (212) and the access region decision unit (213) in the nonvolatile storage device (200) realize data recording which satisfies the access speed reported in advance upon the data recording. Thus, it is possible to access all the nonvolatile storage devices at a desired speed regardless of difference in characteristics of the recording speed of each of the nonvolatile storage devices.
