    "Great freeware software, the ultimate disk optimizer"

    November 20, 2011  |   By danwat1234


    The most configurable disk defragmenter and optimizer available. Sorting your computer's system drive file system results and superior rebooting speed, application launch speed, security scan speed and more.
    O&O defrag does this as well, but ultimate defrag also has the ability to put select files and folder as the beginning of the drive volume for the fastest speeds possible, and this high performance selection can be optimized (if desired) differently from the other selections).

    There is also a archive section so you can tell Ultimate Defrag to put files that you hardly use or doesn't need high I/O speed to be put at the end of the drive volume so it does not slow down the speed of data that need high I/O speed.


    The only downside to this software is high CPU usage when it comes to NTFS compressed file systems. As in, when you select a large majority of your files on your NTFS file system to be comrpessed using NTFS compression.
    Even on a high end 3GHZ+ Core 2 duo system, the CPU is often the bottleneck, not the hard drive.
