It is sort of a faith situation.Īll three of these do something better than the other though my over all favorite is DiskWarrior.It is the first to be run in a pinch.Īs for the optimizing I have used all three with equally good results. I can not really say that one optimizes better than the other for I really have no way of examining the files outside of using these three utilities. I use DiskWarrior/OptimizerPlus and TTP also. But for sure you need more than one arrow in your quiver. I have been using Norton for years and with the exception of version 4.5 which broke things not needing to be fixed and visa-versa It has been reliable. Data and files are the same thing to the OS as far as storage is concerned. There is no difference between data and file fragmentation. TechTool Pro and Disk Optimizer both defrag.įile fragmentation and free space fragmentation. Although not as critical as file fragmentation it can eventually lead to file fragmenation if the free space fragments become too many and too small. More often than not, free space fragmentation is spread over many, many areas of the disk. More work ~ more time.įree space fragmentation is where the free space on your disk is spread over more than one contiguous area of your disk.

Thus, when you, or an application, request a file, the read heads of the drive have to work that much more to find the file. This is when a file gets written to a disk in more than one area of the disk. This happens on any disk, on any platform, running any OS. There are two types of fragmentation on a disk. Both products, and yes SpeedDisk too, defrag. To whomever said that TTP and PlusOptiizer don't defrag.
