The storage device is provided with a synchronization controller to realize synchronization control of information for the other storage devices when information is updated. This synchronization controller is further provided with a synchronization level registration table for registration and management of synchronization levels for every class of information and a synchronization interval registration table for registration and management of synchronization intervals of information pieces for the synchronization levels. Consequently, a load of communications may be alleviated by realizing common sharing/synchronization of information pieces among different systems and particularly by realizing loose common sharing/synchronization of information pieces depending on the characteristics of the information.
