It's not your imagination, computer systems really do slow down over time, and disk fragmentation is the cause. Disk fragmentation builds rapidly, causing system slowdowns, slow boot times, crashes, freeze ups, and even total system failures. The only way to obtain full-throttle performance is to keep your systems defragmented. You can run yourself ragged manually defragmenting every workstation, desktop, laptop and server on a regular basis; or you can have the problem taken care of automatically with NEW Diskeeper 9!
