Diskeeper has been around for some time – indeed, the drive defragmenter included in Windows XP was a 'lite' version of release 8.0.
As Windows opens and closes files, or applications are installed, these are written to the first available section on the hard drive, with the end result that data is scattered across a disk and performance can deteriorate.
For the vast majority of users, the disk-defrag utility in Windows is something they would probably run every six months and consider sufficient, so why spend more than £40 on a single utility? Diskeeper has added a range of features, but anyone striving for maximum performance will probably be concerned about just one: the 'Set and Forget It' feature. In theory, your hard drive can be maintained at top speed without any effort on your part.
Diskeeper Professional Premier is considerably faster than the built-in utility. Analysis was completed in a fraction of the time and manual defragmentation was quick – although the speed of this process depends on the size of hard drive. The Premier edition reviewed here employs I-FAAST, a technology that uses what Diskeeper calls 'adaptive file-sequencing' to monitor which files are most frequently accessed and optimise those for performance.
The interface has been redesigned. It's generally simple to use, while offering a host of options for the power users among us to configure the way the program works. Other new features include historical reporting and enhancements to background defragging, which could be a nuisance with previous versions, slowing systems down just when you needed to work on them.
