In some embodiments, a storage system may include, but is not limited to, a master volume, one or more link volumes, a master data read frequency determination unit, a load state determination unit, a copy target determination unit, a copy destination determination unit, and a copy controller. The copy target determination unit determines copy target data in the data stored in the master volume on the basis of the read frequency when the load state determination unit determines that the master volume is in a high load state. The copy destination determination unit determines at least one of the one or more link volumes as a copy destination link volume of the copy target data on the basis of the load state of each of the one or more link volumes. The copy controller copies the copy target data into the copy destination link volume.
