Abstract
According to one embodiment, a storage device includes a storage configured to store data and a controller configured to control the storage. When receiving an instruction to read data from the storage is received, the controller determines whether or not a failure is in the storage device which is a target of the data read. When a failure is acknowledged, the controller refers to a different storage device storing the data including the same data as the data, acquires the same data from the different storage device, and outputs the acquired data to a source of the instruction.
