Abstract
The storage system includes a controller and a storage drive accessible from the controller. The controller includes a memory and a processing unit. The memory includes a first cache area in which the writing of data by the storage drive is permitted, and a second cache area in which the writing of data by the storage drive is prohibited. A In the first cache area, the storage of data, by staging-in-advance in response to a read request for a sequential read, by the processing unit is permitted, and the storage of cache data in a dirty state by the processing unit is prohibited. In the second cache area, the storage of the cache data in the dirty state by the processing unit is permitted.
