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.

    "I'd recommend that everyone considering this software buy an SSD instead" - ummm, SSD's are a LITTLE on the over-priced side for the amount of disk space provided (think I'll wait a year or two and use a free defragger instead). Agree with eman, not enough improvement/change to justify a version upgrade.

    I don't like defragmentation software. That's why I bought an SSD with TRIM support. I'd recommend that everyone considering this software buy an SSD instead. Then you won't need to waste your money on defragmentation software.

    I hope this was an authorized posting of the PD11 beta.

    I've been testing it too, but unlike people who have no idea how to test software, I've found several bugs, one of which is pretty bad (but only for some users).

    The duplicate finder is ... "OK" but it would be nice to know whether it's doing a full binary compare, or is using some crappy algorithm like CRC32. (I won't trust it for real use until I know the answer.) Using a hash algorithm--any hash algorithm--would make no sense since to calculate the hash, you need to read the whole file anyway, so you may as well do a binary comparison.

    This version does analyze and defragment faster than prior versions, which is a nice improvement, but hardly enough to justify a full version increment. The ability to select/customize SMARTPlacement algorithms (in Pro and above) is another nice addition.

    Five stars not for a perfect product (it's far from it), but for a defragger that improves performance more than any other, and which helps prevent future fragmentation better as well, and for a company that offers very good support.

    I like the duplicate cleaner in version 10, the ease of installation compared to Diskeeper, it's made in America, and it works.

    I've been Beta testing version 11 & the Beta's have been much faster than version 10. I haven't had any issues except certain features relating to graphics haven't been implemented yet. The best defragger bar none.

    Gyrolin I disagree with you 100% & ask what defragger do you use that's better?

    emanresU deriseD, I've been Beta testing on PC's since the 286 & spend my working life in comms rooms. I still have no found any major flaws yet, & have sent the minor issues/bugs to Raxco via the survey & the forum. It will be a good prog on final.
