Abstract:
A storage control device that controls a solid state drive group including two or more solid state drives sharing data storage includes a detector that detects a wear state of each of the solid state drives, a separation controller that separates a solid state drive having a wear value, which represents a wear state, exceeding a first threshold among the solid state drives, and an enlargement controller that, when detecting a solid state drive having a wear value, which represents a wear state, exceeding a second threshold less than the first threshold among the solid state drives in the solid state drive group, enlarges a difference in a wear value, which represents a wear state, between the solid state drive having the wear value exceeding the second threshold and a remainder of the solid state drives.
