Microsoft has published many articles on the adverse affect of file fragmentation
on Windows operating system performance. The symptoms of fragmentation are slow
boot times, slow application launch times, application errors and potential system
hangs and crashes. The Windows operating system has historically included a basic
defrag utility to help address these issues. And the utility included in Windows
7 is an improvement on previous Windows versions.
However, the Windows defragmentation tool does not offer a complete solution. It
offers an improved, but basic, utility that is limited in it's functionality, flexibility
and strategies for preventing defragmentation and optimizing disk performance.
Microsoft recognizes that there are many users who require a more robust, full-featured
solution and works with companies such as Raxco Software through the Microsoft Partner
Program to ensure that you have access to the tools you need to keep your Windows
7 environment running at peak performance.
Scheduled Defrag vs. Automatic Background Optimization and Fragmentation Prevention
The Windows 7 defrag utility allows users to set up a scheduled time for defragmentation
to occur. This is fine for correcting issues after they have already become problems.
PerfectDisk takes a different approach - automatic background optimization and fragmentation
prevention. With OptiWrite, PerfectDisk is able to detect when Windows is going
to fragment files and intelligently redirects I/O so that most fragmentation does
not occur in the first place. In addition, SMARTPlacement optimizes the placement
of files on your disk based on your unique usage patterns to minimize refragmentation.
For the limited amount of fragmentation that does occur, StealthPatrol is able to
perform the defragmentation when your system is not busy.
Advanced Boot Time Defragmentation
Microsoft recommends performing a boot time defrag for faster start-up times, but
the Windows 7 defrag utility does not support this functionality.
PerfectDisk provides advanced boot time defrag capability that is able to defragment
files that otherwise would remain fragmented such as the Windows pagefile.sys or
the file system's MFT (Master File Table).
Centralized Management and Control
One of the key shortcomings of the Windows 7 defragmentation is its lack of enterprise
management and control. This forces IT staff to manually configure the Windows 7
defragmenter on a machine-by-machine basis. Since no centralized reporting is provided,
IT staff will always be completely unaware of either the quality of the job being
done, or whether defrag tasks are even executing as planned.
Enterprise management of PerfectDisk is provided by the free PerfectDisk Enterprise
Console. The Console can be used to easily install, deploy, configure, manage and
report on PerfectDisk across computers, servers and virtual environments.
"After just the first use, PerfectDisk made a very noticeable difference in
how Windows 7 and my personal system, which is a very high performance one, responds.
And I can assure you that after 30 years in this business, I do not throw around
accolades or recommendations lightly."
