With O&O SpeedCheck you can simulate your Windows system in a fragmented and defragmented state. No data is written in the simulation, it simply reads test data from the hard disk. After completion of the simulation you will be shown a comparison of the two test times, and the possible increase in speed available to you. You can see just how much your PC could be accelerated by regular and thorough defragmentation.
The possible resulting increase in system speed is measured by comparing the respective total times for both runs. In order to nullify as far as possible any side effects caused by the operating system and applications running in the background, both test runs are carried out five times.
We still recommend however that you avoid running other applications during the test runs. File operations in particular can lead to a distortion of the result.
