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.

"Perfection is difficult to improve on...!!!"

March 27, 2015  |  By ClintonBacon

 |  Version: Smart Defrag 4.0.2.690

Pros

Clean and simple, quick to defrag and easy to use. The new defrag 4 adds peace of mind.

Cons

That I have licenced all the ACS products; now defrag 4 wants me to buy a license even though I have a license for defrag 3 that is still remaining.

Summary

I started using defrag years ago, then I started using advanced systemcare. Eventually I bought a license for advanced systemcare and enjoyed the product so much that I now buy a license every year for all the IObit products. Except now defrag 4 has come out and I can not use the balance of my defrag 3's license fro defrag 4.
It is difficult to improve on perfection, yet somehow every time IObit release a new product or an upgrade they do improve on perfection.

Well done development team, keep up the good work.

Your biggest IObit fan. (..my licensing history is proof of this)

"Wonderful Support Experience"

March 26, 2015  |  By bjpaffd

 |  Version: Smart Defrag 4.0.2.690

Pros

I have used Smart Defrag for years and initially I had issues with Smart Defrag 4. It was crashing. I contacted IObit support and they were very responsive and helpful in getting it corrected. I was surprised that for a free product I would get this level of attention., It seems today you can't even get it on "paid" products.

Cons

I have no con

Summary

I highly recommend this product and the wonderful support they provide.

"Reduced my free drive space by 42 Gb"

March 24, 2015  |  By Zzdee

 |  Version: Smart Defrag 4.0.2.690

Pros

None, the interface is confusing

Cons

Severely reduced my free drive space by 42 GB instead of increasing it. This is HUGE!!! How in the world did this happen?

And does not shut down the computer after operation despite I telling it to.

Summary

One word - Garbage.

And beware: They only offer the latest version for download even though it is still in BETA. That means YOU are the guinea pig.

Updated on Mar 24, 2015

Everything I said is 100% true. I am not a shill or troll. This is my real experience with Iobit's Smart Defrag 4. I totally regret installing and using it.

I have since installed Auslogic DiscDefrag but it cannot recover back the 42 GB lost. Its free BoostSpeed7 managed to recover 1 GB back, but that is all.

"A Fast and Stylish disk defraggler, and it's free!"

March 21, 2015

 |  Version: Smart Defrag 4.0.2.690

Pros

× Fast;
× Automatic defrag at given time;
× Defrag at boot time;
× Disk health reports;
× Select one or more drive to work on;
× 3 Defrag modes: Normal, +Fast optimization, +Full Optimization;
× Analyse of the disk before starting the defrag, useful to know the disk health;

× Skinable interface;
× User can select the "Map" colors;
× The settings window have a good quantity of options;
× Many Languages;
× Can exclude folders from defrag;
× Can chose the max file size, when to start/pause the defrag if the CPU is idle/high;

Cons

Nothing to say, it do it's job greatly.

Summary

I tested a lot of disk defragglers, PC Health management suites that install many others app's, or fishy softwares that's really slow?
But I tested the iobit softwares, and they are really good, like the SmartRam Booster in the iobit advanced system care suite, Smart Defrag is really a great and usefull app.
The bonus is the automatic defrag when boot, you can power your pc and the work will be started before launching windows, and it's fast too.
What's more is that it's a Freeware software ! and this is very great !
