Diskeeper with IntelliWrite prevents up to 85% of fragmentation and makes every system faster and more efficient than ever before possible. When fragmentation occurs, I/O resources have already been wasted. Now most fragmentation can be prevented, significantly speeding up file reads and writes, boot-ups, backups and AV scan. Clean fragmentation-proof disks last longer, use less energy, require less cooling and zero administrative support. Diskeeper also includes powerful defrag engines for what isn't prevented and runs in real-time, with zero resource conflicts.
