The harm of defragmentation to the hard disk:

Disk defragmentation will frequently erase and write to the hard disk, which will greatly reduce the life of the Flash inside the SSD. Because disk defragmentation will perform a read and write operation similar to the entire disk for the entire disk space. The built-in garbage collection mechanism of the solid-state disk is already a good "disk defragmentation". The SSD controller has its own software (algorithm) to clean up the Flash space.

Suggestion:

The disk defragmentation function of Windows is a product of the era of mechanical hard disks and is not suitable for SSDs. My suggestion is that SSD users don't have to use disk defragmentation. Therefore, when using SSD solid state drives, it is strongly recommended to turn off the disk defragmentation scheduled task in the Windows scheduled task.
