Media Review

"IObit Smart Defrag 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's updates include a new defrag engine, specialized Game Defrag, a cool new look, and many more language options (35 and counting)."


User Review

"I have been using Iobit products for a good many years now. Because I am running an older machine with 6 drives, including 2 external, I find that Iobit's "Smart Defrag Pro" has served me very well. Being an older machine,, my computer system tends to become fragmented quite easily. Having My "Smart Defrag Pro" set to auto defrag, and running a "Defrag and Optimize" once a week, keeps my system running smooth and well. Iobit is constantly upgrading and striving to make the product even better as time goes by. I am well pleased with this product."

"I run a combination of RAID 0 SSDs and RAID 0 HDDs and use Smart Defrag Pro to analyse, defrag and keep my drives running at peak performance. As with all IObit software it is easy to install, use and very reliable. Just set it up and forget it. Smart Defrag has a very small memory foot print so it won't slow down your system. Definitely recommended!"

"I use Smart Defrag since its creation on several PCs and from the beginning with the members of my computer club we were able to see the continuous improvements. It was perfect for them, except the English language. So I invested for IObit in the French translation. From now on, the French IT magazines strongly recommend Smart Defrag, including with Windows 10 Optimiser, for a more robust and accurate diagnosis with options to speed up the system startup."

"I don't know how I could be more satisfied with Smart Defrag. It works like a charm everytime, and all I have to do is run the program and everything is clean and I'm absolutely 100% satisfied, not only with the program, but also with the quick reply when I needed advice on how to manage the problems I might have had. That I appreciate very much."
