STORAGE DEVICE OF COMPUTER

PROBLEM TO BE SOLVED: To prevent a memory of a storage device limited in write cycles from being unnecessarily consumed, the memory storing data to be written and controlling the number of rewrites by false writing to control the lifetime, in a computer that treats the data as files and converts file-writing to storage-writing, where write addresses are dynamically allocated. SOLUTION: The storage device of a computer that temporarily stores, in response to a write request from an application program 100, data in a memory 103 before being stored in a silicon disk storage device 102, and migrates the data from the memory to the silicon disk storage device at every predetermined period. The memory stores the content to be stored as file name and data, and converts them to the address of the silicon disk storage device and data during migration to the silicon disk storage device.
