A new version of popular disk Defragmentation software Diskeeper has been released. Diskeeper 2009 (version 13.0.835) introduces a new feature called InvisiTasking which allows the program to defragment the file system in real time. I-FAAST 2.0 and Frag Shield 2.0 are two more updated features in the new version. This post features the Diskeeper 2009 Pro Premier version which is targeted at power users.

I have not used Diskeeper extensively so I cannot comment on its effectiveness. So far, the reviews I found (for version 2008) on the internet seem to be largely positive. Diskeeper 2009 is so new and currently there aren’t many reviews around for this version.

    O&O Defrag is better. Diskeeper is a resource hog, and the defrag is not as optimal as with O&O. The set it and forget it option is buggy and when it does work, you're pc will be almost unusable.

    Also, Diskeeper supports Scientology!

    I've used Diskeeper professional 2009 since its release last year, and it's one of the best performing and most trouble-free utilities I have on my system. It's unintrusive, doesn't conflict with any other application and simply does a fantastic job of keeping the drives tidy. Highly recommended.
