Flexibility
Been using since W2K days - love the options for scheduling and how you want your drives defragged.

Con
•••
High price point
The price could very easily put one off. Unlike many other products, PerfectDisk has no free features beyond the thirty day trial. Furthermore, the only way to guarantee unlimited utility past three computers is to purchase a total home license which costs $49.99.

Can be pretty slow
It can take a day to complete defragging. If you run the Windows built in defragger first, then it runs much much faster afterwards.

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

PleasantIxtab's Experience
Very solid and very useful Gaming defragmentation program. Optimizes on schedules and is even intelligent enough to know when you are using your system and when you are not.

•••
As boot time degrag
You can set manual or scheduled boot time defrag.

•••
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.

•••
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
