Abstract: A storage system includes a host, a back plane including a switching block and connected to the host, a plurality of storage sets connected to the back plane to receive power from the host, and a battery module connected to the back plane to supply spare power to at least one storage set of the plurality of storage sets through the switching block, when an abnormal power drop is detected in the at least one storage set of the plurality of storage sets. The battery module controls the at least one storage set to perform a data flushing operation, when power less than or equal to a threshold value is detected in the at least one storage set after supplying the spare power.
