Perfectdisk

We have deployed Perfectdisk by Raxco software on our desktops here. The tool is very easy to use - then again, what disk defragmentation tool isn't simplistic.

One of the cool things that Perfectdisk offers is offline defragmentation, which basically defrags the pagefile and other system files when you reboot. I've noticed immediate performance increases on some machines after only one defrag even after running Window's built in defragging tool.
