A spanned volume is a volume that uses more than one physical disk. You can use any unallocated space left on disks to create a spanned volume. It also can include more than one unallocated space on a single disk while free spaces can be of any size. The only benefit of spanned volumes is the use of unallocated space that may have originated from imported disks or specific volume arrangements. The main disadvantage is the risk of losing the volume if one disk participating in the spanned volume fails. A faulty portion means a faulty spanned volume! There are no performance benefits when implementing spanned volumes.
