Image It’s time for another poll. Today we want to ask you about disk defrag tools. What program do you use to defragment your hard drive?

Anyone who’s owned a Windows PC for a long time will probably agree that eventually you have to defrag the hard drive. As you move files around and keep installing new programs your disk gets fragmented. Fragmented files take longer to run and results in slower performance. So if you want to keep the hard drive at its peak performance, make sure to defragment your computer once in a while.

As with any other piece of software, some defrag tools tend to perform a lot faster and better than the other ones. While certain people prefer in-built Windows Defragmention Tool, others (incl. myself) prefer something else. There are also those who are simply not aware of alternatives.

Anyhow, what do you use? Please vote! (you can select up to 2 options)

    I use O&O Defrag; why haven't you got Paragon Total Defrag listed? It has to be one of the most thorough defragmenters on the market.

    Doing the defrag process is so 'old-school'. The new processors and fast hard drives make the results non-noticeable for any end-user speed comparison. I don't do. It just adds extra wear and tear on the HD causing an earlier death, than not doing...

      I dunno... anyone who hasn't defragmented the drive for some months should notice a considerable improvement after defragging. I saw it many times.

        ..would like to see the specs on processor/HD used and the improvement results. Unless you can show an advantage of doing, over paying for a new HD early, from all the extra seeking/rewriting over time completing this process 'x' times, I would say don't do...

    what about the defrag tool in Tune up utilities?

      I decided to include only defrag tools and left out tune-up suites.

    I was under the understanding that NTFS deals quite well with fragmented files and is designed to handle distributed block storage efficiently. Defragmenting a harddrive provides speed gain only with FAT disk systems and only has advantage if you might need to pursue some data recovery.

    Why don't you have Puran Defrag and UltimateDefrag 2008 listed?

    I use Diskeeper 2008 pro on my Vista and XP boxes, and it's awesome. It just has to be installed, and it handles all the defragmentation related tasks on it's own after that. Even with four 500GB drives on the XP machine, it keeps them in excellent shape, working in the background. Defrags are fast and thorough, and it has many useful features like proactive resizing of the MFT to prevent fragmentation, multiple defrag modes (incl VSS defrag for Vista), excellent UI etc. I think Diskeeper is far superior to the other utilities especially if you have a system with more than one HDD in it.

    I've worked for CNET and PCMag. We would get questions about this all the time. Through the years of testing most of the defrag utilities we could not really say that any are any better that the default windows defrag. People's claims of some being faster than others were never seen in the test I've conducted.

    We would always conclude that it was never worth paying for a defrag utility. The free ones are all based on user preference.

      Yes, I have come to this conclusion as well... some have nicer progress dialogues and better interfaces and more features... but pretty much do the same thing

        I would say the main difference is defragging speed. The JKDefrag is abt 5 x times faster then default Windows defrag tool.

    It's worthless and every other defrag app does a much better job and takes less time to complete.

    D47's comment brings nothing to the table, can't you mod comments like this? they really spoil mine and probably others enjoyment of this blog!

    Note : This is not born out of a difference of opinion. Mackenzie Morgan makes a similar point but in a constructive way that's the difference!

    I'm sorry, i use an OS that doesn't fuck up my files, i wouldn't know what you guys are talking about.

    It's Defraggler for me; the tool doesn't slow down my system and allows me to do other stuff simultaneously. :)

    I use Power Defragmenter GUI and I find it very good. I use Page Defrag at every boot too.

      Wasn't JKDefrag fault. Read their information. They use the same API as Windows Default to do any physical movement of data. It is supplied with Windows.

      Now the question would be are you using FAT32 or NFTS format? FAT32 is much less secure and prone to failures.

    On Windows, I always just used the built-in one. On Linux, nothing:

    Ultimate defrag ( - looks and works beautifully for me.

    I choose Contig, but in all actuality I use a front-end for that called "Power Defrag". It works wonders and does a much better job of defragmenting my HD than the default Windows one does.

    I don't Defragment at all

    As most people will know windows defrag is Diskeeper without the extra option, good enough for me!

    you for got UltimateDefrag Free Edition

    I use both the above and "JkDefrag GUI" for my disk defragmenting needs.
