Ranked in these QuestionsQuestion Ranking
Pros

You can set multiple defrag schedules and have Smart Defrag simply exit, shut the PC down, or continue monitoring.

You can set manual or scheduled boot time defrag.
Pro Can set defrag pauses on specific programs
You can set Smart Defrag to watch for specific programs to be running and then pause any running defrag until this program is no longer running, such as games or game launchers.
Pro Benefits solid state and mechanical drives alike, including systems with both types
The standard TRIM function is used to maintain solid state drives while the defragment function services the needs of the spinning platter drives
Cons
Con Attempts to install additional software alongside it, and installs IObit Uninstaller or other IObit software if the user selects 'default' or simply selects 'ok' without paying attention.
The package is becoming more bloated and encumbered with efforts to monetize it as it matures. The free version will continue to advertise purchasing the PRO version and other IOBit software until purchased which is understandable but annoying.
