Abstract:
Provided is a storage medium management system, in which when the same data as that stored in a first physical storage area is stored in a second physical storage area, a storage system connected to a host computer compares the number of remaining rewritable times for the first physical storage area and the number of remaining rewritable times for the second physical storage area with each other. When the number of remaining rewritable times for the first physical storage area is less than the number of remaining rewritable times for the second physical storage area, the storage system writes data written from the host computer to the second physical storage area and copies the data written in the second physical storage area to the first physical storage area.
