This degree of fragmentation is still acceptable for data drives but frequent accessing of such data requires a lot more time than under ideal conditions. This degree of fragmentation is still acceptable for a system drive and indicates that your system is running at an almost ideal level of performance. This is the ideal condition and can only be achieved and maintained by running a defragmentation at regular intervals. LevelĪlmost all files are optimally arranged on the hard disk. Even values of around 15% indicate that the performance of your system is seriously affected, and that a defragmentation is strongly recommended. A value close to 100 is really a worst case scenario – your files are almost completely fragmented. This level can lie between 0% and 100% whereby a lower value (ideally 0%) indicates that your data is not fragmented. O&O Defrag creates a detailed status report about the fragmentation level once the analysis has been completed. Conflicts with shadow copies during defragmentationīy analyzing hard disks, you can get an overview of how files are arranged on a drive, and how heavily fragmented they are.Why is the ClusterView different on HDDs and SSDs?.
