PerfectDisk redefines enterprise disk defragmentation addressing an issue that Microsoft, in various published artices, states is often the cause of poor system performance on a system. Provides the most comprehensive solution for defragmentation by optimizing virtually every file on the system, including the Master File Table ($MFT), all metadata, paging files, and directories. Patented SMART Placement technology arranges files on a disk to ensure that free space is consolidated and the future rate of fragmentation is minimized.

    This is THE best defragger on the market. It is the only one that does not work AGAINST the Windows prefetch system. Auto update can be turned off, I do so on all my installs. I have no problem with having to configure software after installing it.

    I use 12.5 and it is the best. I don't know what these guys are talking about, I can exclude my SSD from any action if I choose to, even though PD has it's own defrag mode for SSD. I can switch off auto update or just be notifed if there is one available. I can set my own defrag level at whatever percentage I want, and it all runs automaticaly. Set it and forget it, great program.

    There are free defraggers just as good, & messing with a solid state drive will shorten its life.

    Why on earth this program runs in the background even if you never do scheduled defragging is just plain stupid & you cannot turn this off.

    OK - if you really want a defragger as fast as PD, cheaper & uses Prefetch try 'Auslogics Pro'. It does not have services running in the background either.

    It's also 3.3 meg against PD's 40 meg. PD's total install on Program Files is 142 Meg against Auslogics 12 Meg - PD also installs in Common Files & in Users - Talk about bloatware?

    Leave this product alone. You can not stop the auto-update process.
    You are not in control anymore. From now on Perfectdisk will decide for you.
    How good software can turn into bad. Pity, Pity.

    Defragging is not as useful as it once was, SSD's don't need defragging and Windows Vista/7 already come with a good defragger, Why waste money when you don't need to?
