Traditional mechanical disk drives need to be defragmented for optimum performance, although Windows now does a good job of doing this automatically. Some software companies claim that their tools can “optimize” SSDs, just as disk defragmenters could speed up mechanical drives.

The reality is that modern operating systems and solid-state drive controllers do a good job of keeping themselves optimized if you use a solid-state drive properly. You don’t need to run an SSD optimization program like you’d run a disk defragmenter.
