Provided is a cache device which can minimize probability of data loss in a storage device in which write data and read data are separately cached. The cache device includes a write cache including a first storing unit that temporarily stores write data to be written in external storage devices and is predicted that a failure occurs at the first time and a second storing unit that temporarily stores the write data and is predicted that a failure occurs at the second time being later than the first time by a predetermined failure handling time or more, and a read cache including a third storing unit that temporarily stores read data to be read from the external storage devices. |
