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 it builds fragmentation. Manual, single-pass defragmenters simply can't keep up - in order to maintain performance, you'd likely spend more time defragmenting than you did using the computer! Why bother with a time-consuming manual process, when Diskeeper 9 Professional Edition simply makes the problems of fragmentation go away forever? Diskeeper 9 Professional Edition allows custom configuration tailored to the way you use your system. Fine-tune Diskeeper to your likings or select the default options then Set It and Forget It, and you'll never need to worry about fragmentation again!
