Media Review

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

"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)."

"Smart defrag is a very well behaved disk defrag software."

"Smart defrag is a very well behaved disk defrag software, operating in the background whenever computer is idle so that you hardly notice it. As a result: drives are permanently defragmented allowing rapid access and less wear and tear. Smart defrag is the best Free disk defragmenter I've ever used and I'll definitely recommend it to my family and friends!"

User Review

"It is easy to use, must have utility, for your hard disc or SSD."

"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!"
