UltimateDefrag lets you defrag and optimize your hard drive any way you want to. Hard drive file use adheres to the Pareto Rule of 80/20. 80% of the time you only use 20% of the files on your hard drive.
UltimateDefrag lets you place those unused files out of the way onto the slower tracks of your drive.
UltimateDefrag also considers the high performance areas of your hard drive (the outer tracks) and enables you to strategically place the files and folders you want the best performance from to these faster outer tracks.
UltimateDefrag also provides the first true disk display metaphor in a defragger. UltimateDefrag can place Directories next to your MFT for very fast MFT/Directory transactions.
This alone vastly accelerates performance of your hard drive. Includes over 55 total defrag method combinations.
When done right, your hard drive performance will increase by up to 100%.
