This true data quality index replaces the dangerously misleading Disk Maps. Working with it is the only way to avoid slowdowns!
Our patented technology indicates your hard drive's actual state of fragmentation. Like the Richter scale that measures earthquakes, this is a logarithmic scale: each notch indicates a state of fragmentation that is X10 in severity than the previous one.

Hard drives are vulnerable. If you let them reach an advanced fragmentation level (indicated in red), defrag will no longer work as intended. That point of no return is to be avoided: past that threshold, the hard disk performance will decrease, until it eventually becomes unusable.

Our solution is simple and effective. We monitor the hard disk, and let you know exactly when to defrag. This preventative measure might add a year or more to the life of your computer!
