Abstract
A storage system is provided that has a plurality of flash packages and a storage controller that controls read/write processing between a host and the flash packages. When data identical to data written in a second address of a second flash package of the plurality of flash packages is written to a first address of a first flash package of the plurality of flash packages, the storage system may store the second address in the first package in association with the first address, and perform deduplication. When the first flash package stores the second address in association with the first address and a read request for the first address is received from the storage controller, the first flash package may return the second address to the storage controller. In response to receiving the second address, the storage controller may acquire target read data from the second flash package.
