Abstract
The efficiency of the maintenance of a storage apparatus including a plurality of flash drives can be enhanced. In a storage apparatus including a plurality of SSDs and a CPU, the CPU specifies, based on lifetimes of the SSDs depending on amounts of data written to the SSDs, the SSD to be replaced on a scheduled maintenance date, gives notice of the SSD specified to be replaced, and copies data in the SSD to be replaced to another SSD by the scheduled maintenance date on which the replacement is to be performed.
