Abstract
A storage control device is connected to a disk device that retains write commands including area specifying information specifying areas as write targets and including write object data as write objects and performs writing onto a disk based on the retained write commands. The storage control device includes a controller cache memory in which data read from the disk device is cached, and controller circuitry that generates a write command for writing write object data of a write command received at a second point of time later than a first point of time and gap data between an area specified by area specifying information included in the write command received at the second point of time and an area specified by area specifying information included in the write command received at the first point of time, and outputs the generated write command to the disk device.
