All I know is what was in the blurb they sent me.
Here's a copy.
This is not an endorsement of the product - I have absolutely no experience of it, only knowledge of this promotional material.
Many users ask us why they should decide to buy O&O Defrag 11 Pro when Windows has its own defragmentation program. The basic principle is the same with both the Windows defragmentation and
O&O Defrag 11 Pro:
Fragments of single files are packed together so that the disk write-read heads decrease their overall movement while reading a file, reduce the revolution time and thus reduce the time taken to read-access files.
However,
O&O Defrag 11 Pro offers you so much more: the integrated automated background monitor and defragmenter ensure an optimal level of computer performance. The O&O ActiveGuard Pro function keeps your computer defragmented without impacting your work or gaming experience, since only available resources are tapped into while defragmenting.
To suit all needs: 5 defragmentation methods used by O&O Defrag 11 Pro
O&O Defrag 11 Pro combines five different defragmentation methods. There's a method to suit every user, depending on computer usage and your specific needs while defragmenting.
The STEALTH-Method
The STEALTH method is the fastest of all methods and is a great resource saver. Since the defragmentation is aimed at achieving the highest possible speed, it is not quite as thorough as some of the further methods below.
The SPACE-Method
The SPACE method can be seen as an extension of the STEALTH method. The basic difference lies in the enlargement of the continuous available storage space. In other words, the user is literally able to store data in the front of the hard disk so that the space in the end is available for new data.
The COMPLETE-Methods
The COMPLETE method not only defragments your data, it also re-organizes it. As a result, accessing data becomes much faster, since the data last used (COMPLETE/Access method) or changed (COMPLETE/Modified method) is saved in the area, where the write-read head of the hard disk can access them the quickest. In addition, you can also reorganize your data according to their names (COMPLETE/Name method).
The general advantage of the COMPLETE methods is the maximization of the performance while writing (COMPLETE/Access method) and reading (COMPLETE/Modified and COMPLETE/Name method).
