The files saved on your hard disk will become fragmented for various reasons. Because of this, your hard disk is extra busy gathering data from different fragments located at various locations on the hard disk in order to access your files. This process degrades your hard disk performance and overall system speed which gets gradually worse over time. In addition, the read/write speed of your hard disk varies by location and the files on your hard disk are randomly distributed. Therefore, you lose any potential speed gains from other system optimization programs.

    ULTIMATE DEFRAG is the best of all!!! The features, User Interface (circular hard drive plate is mimicked), different types of defragmentation methods not available from all others, and its capabilities. Tested all these defrags apps mentioned above but nothing comes close to Ultimate Defrag. Its defragmentation manual and 101 alone are even exceptional. The only downside is, it is not that popular. See it for yourself!

    UltraDefrag is not free.
    MyDefrag was last updated in 2009, and the main executable is a password protected archive, so it’s unusable.
