    Disk fragmentation is generally main cause of slow and unstable computer performance. Smart Defrag helps defragment your hard drive most efficiently. Smart Defrag not only defragments computer deeply but optimizes disk performance. With 'install it and forget it' feature, Smart Defrag works automatically and quietly in the background on your PC, keeping your hard disk running at its speediest. Smart Defrag is complete free for home, organization, and business.

    be careful with this one - Iobit is accused of stealing AV and malware signatures from Malwarebytes - see the discussion on WOT:

    Iobit is not to be trusted anymore.

    Its a nice program, but I don't think it defrags in the back ground very well. I also don't think it defrags the best. I think JKdefrag or the windows one (for best boot times, I think) work better. Especially JKdefrag.

    JKDefrag is indeed lighter on system resources than SD, but I still prefer SmartDefrag.

    Its user interface is more friendly and it features more options than JKdefrag.

    I would recommend using SmartDefrag on new and fast computers and using JKdefrag on older/slower computers, and using

    Maybe not as good as some of the other defraggers out there, but is the first on my netbook (Asus 1000H) that works without bringing it to a grinding halt.

    This one's great, and a lot better than standard windows defrag. I see a lot of people saying JKDefrag is good as well, so i'll give that one a try too.

    Same with BSWE1987 and ogre. Tried SD for a while, and initially satisfied with it. Few hours after that, tried JkDefrag and I got even more satisfied!
