Which defragmentation software do you use?

[Kuttz]

I believe there is no need to use defrag software and windows will do that automatically during system idle time and SSDs don't like or benefit form defraging either. Gone are the days with windows 98,XP machines you need to defrag your HDD every few weeks.

Well for such regular maintenance then defragmentation is fine but assure that any files which are not under on fast access will not moved due to its nature behaviour; clean any remnants as possible to see if possible to arrange those free space, however time will come where HDD life shell counts which replacement is the only choice.
