1. Disk volumes need to be defragged.
2. I prefer PerfectDisk (defraggler seems to work nicely too) - both are faster than Diskeeper, and all three are many times better than the Default Defragger.
3. Disk defrag is separate from Index defrag. Idx defrags must also be done.
4. In addition to defrag, you should verify cluster sizes and paritition alignment of your database volumes. These will also have significant impact on disk performance.
5. I would also recommend shutting down SQL services - but it is not required.
