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.

Data storage system configuration to perform data rebuild operation via reduced read requests

A storage device includes a non-volatile memory including a plurality of memory blocks. The storage device performs an alignment operation in response to receipt of an align command. The alignment operation converts a received logical address of a logical segment into a physical address and allocates the physical address to a physical block address corresponding to a free block. The storage device is further configured to performs a garbage collection in units of the physical block address that indicates one memory block.
