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).

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.

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

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