Windows 11, 10, 8, 7 has built-in disk defragment tools, including Disk Defragmenter and defrag Command Line. Where is disk defrag in Windows 7, 8, 10, 11and how to run it? If you want to optimize the performance of SSD, you can try other methods. Since the SSD can efficiently read the data in the cluster, it is not necessary. But you should not defrag SSD, due to the different working principles of HDD and SSD, doing that will reduce its lifespan. Defragmentation is very necessary for HDD. Instead, it sorts out the data address and changes the address of the data from discontinuous to continuous, so that when the computer reads the data, it shortens the search time and improves the speed. Its purpose is not to extend the storage space. Defragmentation is to re-arrange discontinuous data consecutively on sectors so that the hard drives can work more efficiently.
