Diskeeper Pro Premier Every system, every network, every company suffers from the effects of fragmentation. When fragmentation occurs, the system has already wasted precious I/O resources by writing fragmented files to many spaces on the disk instead of contiguously to one spot. With Diskeeper 2010 performance software, now you can prevent up to 85% of the fragmentation written to disk. Your system runs at maximum performance levels on a clean, fast and efficient disk.
