I got this from ZDNet this morning. I thought I would pass it along. Basically it deals with the speed of virus/malware scans before and after a defrag, but it does seem to show that defragging does have a use that may outweigh the wear and tear on a disc during the defragmentation process.

The white paper.

*as a note, it is put out by a company that produces defrag software.
