Abstract: Provided are a device and method of controlling a dish cache, wherein a time of seeking a disk cache may be shortened and a hit rate of a disk cache may be increased. The device includes a main memory including a buffer cache, a flash memory including a flash cache, and a controller controlling the buffer cache and the flash cache, wherein the buffer cache and the flash cache are enabled to cache a data block stored in a disk, and the controller identifies a position where the data block is cached using metadata.
