The time required for starting up drives in a storage device mounted with both hard disk drives and solid state drives is shortened. A storage controller of the storage device identifies the type (HDD/SSD) of the mounted drives before starting up the drives. The storage controller thereafter performs staggered spinup to the HDDs in several batches. After the startup of HDDs is complete, the storage controller collectively starts up the SSDs. The storage controller determines the drive startup processing based on a pre-set drive startup policy such as reduction of the peak current reduction or shortening of the startup time, and the drive type identification result.
