Short description of Diskeeper Professional Edition 10.0: No matter how powerful your PC is, fragmentation will slow it down—it's just a matter of time. In fact, the harder your system works, the faster fragmentation builds up. Manual, single-pass defragmenters simply can’t keep up—in order to maintain performance; you’d likely spend more time defragmenting than you will using the computer! Diskeeper, the Number One Automatic Defragmenter, simply makes the problems of fragmentation go away forever.
