This is for those that are looking to increase the performace of their hard drives. This will work on both your boot & connected hard drives.
Using a program from http://www.prosofteng.com/products/drive_genius.php
Called Drive Genius. After running this on my main boot drive & I defrag it, I noticed a system that was more responsive & snappier. While still keeping everything stable. So if your looking to get the most out of your system after long months of usage then surely take a look at this program.
