Abstract: A data storage system configured to perform a data rebuild operation via a reduced number of read requests includes a host and a redundant array of independent disks (RAID) device including a plurality of data storage devices. When the host receives data of a first region and data of a second region of a read-requested region of each of the data storage devices in response to a rebuild request, the host receives failed address list information of the second region. The first region is a normal region, and the second region is a faulty region. The host rebuilds the data of the second region based on the failed address list information.
