O&O SpeedCheck for Windows

The description of O&O SpeedCheck - Play With New Friends

Defragmentation is a necessary operation for any stable system. But its result may vary from system to system depending on each configuration. You can get a long process duration and it may not be distinguishable. So instead of doing it anyway and losing time, you may want to check if your system really needs such an operation and what are the results in case you may want to apply such an operation.
