Which tool fits?
O&O Defrag 32
Review O&O Defrag 32 if you want to select optimization methods explicitly and inspect file-access simulations with SpeedCheck. Choose methods for the detected media type.
IObit Smart Defrag Pro
Smart Defrag Pro suits users who want Auto Defrag, Large Files Defrag and Game Optimize in a dedicated drive utility. Game Optimize targets file organization; it does not establish a guaranteed frame-rate improvement. Explore IObit Smart Defrag Pro.
Our selection advice is based on task coverage. Analyze the relevant drive, record the workload you want to improve and compare results under similar conditions. An application delay may have causes unrelated to fragmentation.
Edition scope and maintenance checks
This comparison uses the Pro edition without assuming a release number. IObit reserves Auto Defrag and some boot-time selections for Pro. Its manual excludes SSDs from Boot Time Defrag.
Review enabled drives and actions before scheduling work. Save open work before a boot-time task and keep a current recovery copy. Drive maintenance does not create a backup.
