CNET Editors' review
There are plenty of downloadable defrag utilities to choose from, but it's hard to beat the ease of use and helpful extras in IOBit's Smart Defrag.
With this utility you can quickly analyze your hard drive to check the level of defragmentation before committing to a scan. The interface shows you different colored blocks representing fragmented files, frequently used files, and more, with a helpful key to show what each colored block represents.
When you're ready to pull the trigger, you can choose from a straight defragmentation (fastest), or have Smart Defrag perform either a fast or "deep" optimization after defragmentation. Our test machine has a rather full hard drive, so even using the fast optimization took close to 40 minutes. Depending on your hard drive and level of defragmentation, your mileage may vary.
In addition to the solid defragmentation tools, you can have Smart Defrag automatically defrag the files you use the most without significantly slowing down your system. Even while performing a full defragmention and optimization run, the program barely uses as much as 25MB of RAM, and with just the auto-defrag running continually, it uses about half that amount.
Smart Defrag offers a few extras, including a scheduler so you can set it up to only defrag during downtime on your computer. You can set it to run scans on bootup or even have the app shut down your computer when it's done defragging selected hard drives or partitions.
It's important to note that Smart Defrag is not as essential for those running Windows 7 because the OS defrags continually on it's own. But if you run external drives connected to a Windows 7 computer, this utility will still come in handy for keeping them running smoothly.
Overall, if you want a quick and solid defrag utility to make your computer run more smoothly, with added options for scheduling and other extras, you should definitely download this program. Both beginner and advanced users will have no trouble operating this solid utility.

"Caused a Blue Screen problem on my WIN 7 system"
Version: Smart Defrag 2.3
Pros
Worked fine on an older XP machine.
Cons
SmartDefagDriver.sys turned out to be the source of a recurrding BSD problem. Once uninstalled, the problem went away.
Summary
I'd be wary of installing this again, at least on WIN 7 systems.

"An amazing utility"
Version: Smart Defrag 2.3
Pros
I'm really a user and haven't been paid to rate the product. They impressed me from the start by giving a real trial. Unlike all the others, they fixed most the errors they found resulting in a noticeable increase in my PC performance. Download and installation went without any issues, very small use of resources, and the speed was unbelievable. I thought - this is impossible to do this quickly. So after they finished I used Windows defrag and there was virtually no fragmentation.
Cons
Can't think of any.
