File server data drives typically contain a mix of both small and large files that change frequently and are thus more prone to fragmentation. Perform an initial SMARTPlacement defrag pass to defragment files, and optimize their on-disk placement, as well as to consolidate free space. For peak performance, defragment the drive using SMARTPlacement at least monthly and if conditions warrant, weekly. For the OS drive, perform an initial SMARTPlacement defrag pass as well. Thereafter, defragment the OS drive using SMARTPlacement at least monthly.
