Editors' Review

+

IObit Smart Defrag 4 optimizes your PC to take full advantage of SSD performance while defragmenting your hard disks. Its SSD Trim tool automatically enables system tweaks that typically require experience to apply. Smart Defrag 4's updates include a new defrag engine, specialized Game Defrag, a cool new look, and many more language options (35 and counting).

Pros

Smarter: A new and smarter defrag engine recovers more free space on traditional hard disks but skips solid-state drives (SSDs), which should never be defragmented. The Smart Optimize tool analyzes your system and combines Defrag, Optimize, and Prioritize processes based on speed.

SSD Trim: Smart Defrag 4's Trim tool applies the important TRIM command that helps keep your SSD clean and fast. The Trim tool even has its own disk map.

Accessible disk map: Smart Defrag 4's Settings thoughtfully include an accessible disk map optimized for color-challenged viewers.

Boot Time Defrag: Smart Defrag 4 can quickly defrag drives at boot, and you can easily skip the process and get right to work if you need to. No worries; Boot Time Defrag won't defrag your SSD boot drive.

Cons

SSD DIY: Real power users may still prefer their own SSD tweaks to Smart Defrag 4's Trim tool.

Bottom Line

IObit Smart Defrag 4 is the best defragger we've tried yet.

"Now includes adware."

May 19, 2015  |  By spapadillion

 |  Version: Smart Defrag 4.0.3.725

Pros

Worked as described with some exceptions.

Cons

Actually ADDED 20GB of data during the defragmentation process, as well as installed adware which required reformatting to remove.

Summary

After navigating around the fake download links and shifty programs at cnet.com for 10+ years I'm finally giving up as well. May your death be swift and unnoticed by anyone of consequence.

"written as a Home user"

May 06, 2015  |  By Henry Straley

 |  Version: Smart Defrag 4.0.2.698

Pros

Simple operation, which for most home user is a major plus. One click is all that is needed.
As a home user large fragmented files normally do not occur so is not a problem.

Cons

I do not go looking for problems and as such have not found any. If problems occur will advise soonest.
Oops there is one, this should be part of the main program( Ultimate 8, or Pro) package and updated automatically through it, not as a separate program.

Summary

Very good, with exception not part of main package.

"It used to work, but not for heavy duty HD demands ..."

May 06, 2015  |  By mtodorov69

 |  Version: Smart Defrag 4.0.2.698

Pros

User Interface OK.
Offline defrag.
No problems with reliability.

Cons

Strange lines on interface window resize.
Boot-time defragmentation will give up on heavy fragmented pagefile.sys ...

Summary

It is a dear piece of software, but it can let you down when you need it the most. System was at no time compromised, but heavy fragmented files were left to their own devices.
