File Fragmentation, SANs, NAS, and RAID

This paper explains the behavior and benefit of implementing Diskeeper defragmentation software with intricate modern hardware technologies such as RAID, NAS and SANs. SANs, NAS devices, corporate servers, and even high end workstations and multimedia-centric desktops characteristically implement multiple physical disk drives in some form of fault tolerant disk striping (RAID). Because the purpose of fault tolerant disk striping is to offer redundancy, as well as improved disk performance by splitting the I/O load, it is a common misconception that fragmentation does not have a negative impact.
