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 consider PD Pro to be the best defragmenter available.

    Not the best defragger overall... Sure, unless you look at whether the product in question can actually do its job. If you want a defragger stuck in 1999 (e.g. JustKiddingDefrag), by all means, go for it.

    This version of PerfectDisk (and I'm talking about the major version, that being 10) is a significant improvement over its predecessor in how it handles automatic defragging. The prior version sometimes would never run at all; this version can adjust itself automatically. And of course, unlike JustKiddingDefrag, it supports the features that were added to Windows after 1999, as well as locked files and NTFS metadata.

    What I don't like is the slow interface and the fact that you can't stop a running schedule all at once.

    Probably the most reliable defragmenter if you're buying for your business, but it's not the best defragger overall. Go get JKdefrag for a great, free, set-and-forget algorithm, or UltraDefrag (not their piece of crap new defragger, DefragExpress) from Disktrix. UD is the best defragger, combining MFT placement and size optimization with actually useful file placement (most accessed files to fastest portion of drive, least accessed to slowest area, giving room in the middle for file growth and new data.

    Incidentally, this defrags USB and FW drives perfectly, both pen drives and USB 2.5" and 3.5" enclosures.

    Except for its boot time defragmenter, all others are disapointing.

    Defragging a USB drive is a sure way to purchase a new one. Do not defrag a USB drive, you'll destroy it!

    PD is the finest software made for HD defragmenting
