1. Why defrag? Although disk fragmentation has little effect on normal work, it will significantly reduce the operating speed of the hard disk. This is mainly because the hard disk needs to jump between multiple fragments to read files, which increases the latency of waiting for the disk to rotate to a specified sector. The seek time required to switch tracks with the head. 2. How often to defrag To reduce the effect of fragmentation, Windows 10 offers a program called “Defragment and Optimise Drives” to help users to defrag their hard drives regularly. But, people also might be a little confused, “how often should I defrag Windows 10 computer? Do I need to defrag every day or every week?...” Normally, we suggest personal users defrag the target disk or drive once every 3 months, however, it depends on how deeply you use your computer. If you use it every day for more than 8 hours, you might need to defrag your computer around once every two weeks. For business, enterprise, or government users, we advise defrag once a month, and if your computer performs quite slowly, you can try to defrag immediately. 2 ways to do automatic defragmentationSince regular defragment can improve the performance of your hard drive, you can use the Windows tool to set a schedule to defragment tasks or a convenient tool to allow your device to automatically defrag. ▌1. Defragment and Optimise Drives from Windows“Defragment and Optimise Drives” is a Windows built-in application that can allow users to set their own defragment plan to defrag the target disks or drives regularly.

When the computer executes the defragment task, the computer may become slow and if you’re running other programs at the same time, some data might lose. Therefore, we suggest you turn off the screen saver and do not do other things on the computer, like listening to music, playing games, etc. Let the computer only run the disk defragmentation program to avoid data loss.
