From the developer:
Fragmentation Prevention with OptiWrite®
PerfectDisk's new OptiWrite technology prevents most fragmentation on your drive before it occurs, which prevents your system from slowing down. OptiWrite detects when Windows is going to fragment files and intelligently redirects I/O to stop the fragmentation from occuring. System performance is maintained and the need to utilize CPU and Disk I/O resources to defragment files is greatly reduced.
