O&O SpeedCheck portable 2017

O&O SpeedCheck allows you to simulate your Windows system in a fragmented and defragmented state. As the application runs in a simulated state no data is written, rather it reads test data from the hard disk. On completion of the simulation you are shown a comparison of the two test times, and the possible increase in speed available to you. You can then see how much your PC may be accelerated by undertaking a system defragmentation. portable 2017 free download
