I/O Smart™
This policy takes the concept of run priorities one step further by "throttling" (suspending) the defrag process whenever disk I/O activity is detected on a disk while it is being defragmented. This ensures the defrag process will be transparent to users, no matter how active the disk. When this policy is enabled, defrag will only proceed when there are no other processes requesting disk I/O operations from the volume currently being defragmented. When this policy is disabled, Diskeeper shares disk I/O bandwidth with requests from other processes.
I/O Smart Enhancements
I/O Smart has been enhanced to completely eliminate performance slows related to disk I/Os incurred by defragmentation. I/O Smart technology actively "listens" for I/O requests. During a Diskeeper defragmentation job, if another application or process needs access to the hard drive, Diskeeper intelligently pauses defragmentation until the other program I/O requests are fulfilled. Once that happens, Diskeeper gets the go-ahead to resume defragmentation until another request comes along. Combined with its high-speed engine, Diskeeper can easily defragment using the "spaces" between I/O requests, even on busy servers. This feature is included in all Diskeeper Editions
