Technology
The Lace Level Scale

This true data quality index replaces the dangerously misleading "Disk Maps". Working with it is the only way to avoid slowdowns!

Fragmentation level graph 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!

Which user are you?


  • Unaware User

    Doesn't bother with fragmentation. Gets a new computer every 1-2 years, or lives with a slow machine.

  • Lucky User

    Defrags every once in a while. Sometimes it works great. When it doesn't, the machine turns slow. Eventually it needs to be replaced.

  • Disklace User

    Defrags exactly when required. Saves money on new computers, and never experiences slowdowns. With all files safe and protected, this user sleeps peacefully.

More about the technology behind Lace Watcher

Lace Level is a statistical scalar factor, calibrated by the results of measuring many thousands of real disks of different type and size from users all over the world. The method which implements this factor is patent pending.

The factor data is collected from the physical position of the various file components on the disk and related to the delay caused by this disorder. It also takes into account the distribution of free areas on the disk. This distribution best describes the way the particular computer is being used. The "holes" between the files are the result of deletion of old data on the disk, and therefore reflect the real pattern of the usage of that disk.

A statistical moment factor is calculated for all the elements that cause delay in reading or writing a file. This is then compared to an "ideal" theoretical disk containing the same data as the analyzed disk. The result is shown on a logarithmic scale, similar to the Richter scale method used in measuring earthquakes. The statistical approach ensures usage of the same measurement unit of fragmentation level regardless of the disk size - from tiny USB storage device to 4TB logical disk.
