Think about Defragmentation!!! in Usage of IObit Products Posted December 10, 2008 There is a free version and a paid version of Ultimate Defrag. The paid version will allow you to allocate files for "High Performance" and also to allocate files for "Archiving". The high performance files are placed at the outer track of your HDD (fastest) and the archived files are placed on the inner tracks. I have tested Ultimate Defrag (both free and paid) for a few months now and have come to a conclusion. If you have extreme amounts of Data such as on a server, then perhaps Ultimate Defrag would be good, but for a normal Home PC, Ultimate Defrag is way overkill. Even Disktrix, the developer of UD states that most users would benefit the most using the "Auto" feature of the program. I can tell you that it is possible to spend days and days trying to configure UD to determine what files should be "high performance" and what should be archived. For instance, you can allocate all "DLL" files for high performance and all "ZIP" files to be archived. The bottom line on all this is that we are talking "Mille-seconds" speed improvements for a Home PC. It has been my experience that a good defragment AND optimize program is all a Home PC needs. Let me put it this way: with Ultimate Defrag, I have scheduled every day to simply defragment. Every other day to defragment by "Consolidation", and once a week to defrag by "File and Folder Name". I see NO speed difference after doing all this with UD than I do with simply running Smart Defrag's "Defrag and Optimize"---and trust me on this---Smart Degrag is MUCH easier to use. So, I now use only Smart Defrag and occasionally I use the free version which I found of Paragon Partition Manager. Paragon has a boot-time defrag and also an MFT defrag option, which very, very few programs offer. In the event my Page file gets split up, I use the free Pagedfrg developed by Mark Rusinovich of Sysinternals (which is now part of Microsoft). It works perfectly. Anyway, if you are like me, go ahead and try Ultimate Defrag but you must use the paid version to get the benefits you are asking for. Disktrix will NOT answer any tech questions for their free version. Eventually I think you will find that a good and easy to use program like Smart Defrag works just as well. For years I used Diskeeper and Vopt, then I used O&O and PerfectDisk. I've used the "Defragler" program and the free Auslogics program and I've used a myriad of others. As I stated in another Post, my favorite feature of Smart Defrag is a personal one. If I want, I can start the defrag and optimize running-----and go to bed! Smart Defrag will shut down my system when it is finished. This is what I have started doing. After a long day of PC use, every night I set the Smart Defrag program to do its thing and then shut down my System. When I awake the next morning--I am good to go for another day. Sometimes SIMPLE is BEST!
