We’re often told about the problems that fragmented data can cause and many people wax lyrical about the benefits of defragmenting your hard drive, but does it really make all that much difference?

The answer depends on your hardware specification and varies greatly from system to system. If you’re unlikely to improve performance there’s not much point in running a lengthy defrag.

O&O SpeedCheck helps you to determine this for your computer, taking into consideration all its individual foibles. It does this by simulating the system running in both a fragmented and a defragmented state and then compares the performance. You end up with a percentage score showing how much you could improve performance by running a defrag.

The standalone program requires no installation and runs from wherever it’s situated. Once run it simulates reading a set of files that are fragmented followed by reading the same set of files in a defragmented state.

No real files are used in this process and nothing is written to disk. It simply loads the files from memory, simulating how your system reads files in each state. O&O SpeedCheck runs each reading cycle five times so you get an average and a more accurate score.

Once you’ve got a final score you’re invited to try out O&O Defrag, but you can opt to use any defragmenting program that you like. Alternatively, if the program doesn’t show a significant potential improvement you might like to postpone your defrag session to make better use of your computer’s time.  


Finally you can find out just how much speed you might be able to reclaim by defragmenting your hard drive without laboriously doing so.
