Delivering a unique set of easy-to-use features and benefits not found in any other solution, PerfectDisk? 2008 will make your computer run like new. Work and play faster - and smarter. PerfectDisk makes everything you do on your computer faster - so you can be more efficient at your work or play. PerfectDisk 2008’s patented SMARTPlacement? optimization is paired with its exclusive single-pass defragmentation and Space Restoration Technology? to maximize PC and laptop performance. All controlled and automated according to your unique requirements through AutoPilot Scheduling? or StealthPatrol? unattended background processing.
Why you need to defrag your computer
Every time you use your computer, even when it's brand new, the files on your PC or laptop will continuously become fragmented. This means that these files are split into millions of pieces, and this occurs even more so when you go to add, modify and delete them. So when you go to access a file - even just to read it - it will take much longer than necessary because Windows has to first find each piece of the file before you can even see it. This makes using your computer, and doing everything you want, much slower than it should be. Fragmentation also leads to much slower boot times and will make applications run slow or even potentially cause them to "lock-up" or freeze.
Defragging your computer puts the pieces of your files back together into a single piece - the way they should be. A defragmented computer will boot quicker, files will be accessed faster, and your applications will not hang. A good disk defragger will not only defragment, but will also consolidate the free space on your drives into one large piece so when you create a new file, there will be enough free space to save that file in a single piece, rather than fragmenting right away. Defrag for a faster computer and a healthy PC.
What's New in PerfectDisk? 2008
A brand-new user interface
A new user interface makes it easier than ever to use PerfectDisk. Menus and toolbars have been replaced with a ribbon that organizes and presents capabilities into a set of tabs that correspond to how the product is used. The tabs on the ribbon display the commands that are most relevant for each of the task areas in PerfectDisk. New wizards are also now included, providing easier setup.
StealthPatrol? automatic disk defragmentation
PerfectDisk now provides the ability to automatically perform defragmentation only when your system is idle. Together with the wide range of scheduling options available with AutoPilot Scheduling, PerfectDisk 2008 provides more flexibility, automation and complete control than any other disk defragmenter.
Improved performance and reduced resource usage
PerfectDisk has been enhanced to run even faster during SMARTPlacement defragmentation passes. The engine also now uses 15% - 20% less memory consumption than PerfectDisk 8, which results in additional improved performance.
Selected Files Defrag
PerfectDisk's Single File Defrag has been replaced with Selected Files Defrag, giving users the ability to select multiple files to defragment, rather than the entire drive. The ability also now exists to select files from the "Most Defragmented Files" list for immediate and automatic defragmenting.
Fragmeter
A new graphical view of how fragmented your drive is. PerfectDisk 2008's powerful bit map display of disk drives is now enhanced with a new, colorful and easy-to-view circular graphic of your drive's level of fragmentation.
Free Space Recycler
PerfectDisk now provides the ability to easily and automatically reclaim valuable free space from your Recycle Bin, Temporary Internet Files, and duplicate text, picture, video and music files.
Space Explorer
See a bird's eye view of the space distribution between files and folders inside your drives' directories. PerfectDisk 2008's Space Explorer also allows you to delete large files to recapture valuable space on your drive.
Enhanced system tray icon functionality
Additional capabilities are now available through the system tray icon, providing additional ease-of-use.
Estimated Time to Completion
PerfectDisk now provides the estimated time of day when a defrag run will complete.
Native support for 64-bit platforms
Native support for 64-bit platforms provides improved performance and efficiency on 64-bit platforms.
Enhanced Active Directory Integration
A new Active Directory tab is now available for those enterprises utilizing Active Directory, allowing for easy Active Directory snap-in and loading of the PerfectDisk 2008 Administrative template.
Key Features
Microsoft Certified
Ensures PerfectDisk 2008 meets Microsoft-specified availability, reliability, security, and supportability guidelines that result in a better and safer user experience.
Patented SMARTPlacement? Optimization
PerfectDisk 2008's SMARTPlacement? optimization strategy results in faster subsequent defragmentation runs and faster boot times because many of the files on the drive do not need to be moved at all, since they are placed according to users unique usage patterns. Typical defragmenters waste resources by constantly moving all files around on the drive during every defrag pass.
Space Restoration Technology?
PerfectDisk 2008's exclusive Space Restoration Technology provides the most complete and efficient free space consolidation available today. In a single pass, PerfectDisk 2008 creates the largest piece of contiguous free space possible. This results in less fragmentation occurring when new files are created and also improves write file access time, in addition to read file access time, which is all typical defragmenters focus on. A Consolidate Free Space Defrag option is also available which creates the largest piece of contiguous free space available. This is useful prior to creating large files or in performing partition resizing operations. It is also useful in compressing a virtual hard drive on a virtual machine, as a large amount of contiguous space will be recaptured.
Single-pass File and Free Space Defragmentation
PerfectDisk 2008 performs a complete defragmentation of files and free space in a single pass no matter how large the drive or how badly fragmented the drive. No slowly chipping away at the problem like typical defragmenters. Once and done - and using fewer resources as well. In addition, you have a clear understanding of when your drive has completed its defragmentation.
Complete Automation
PerfectDisk 2008's exclusive AutoPilot Scheduling automates all aspects of defragmentation. Administrators and users have complete flexibility in defining schedules to completely automate the enterprise's defragmentation. For example, schedules can be set to run daily, weekly, or only when the user's screen saver is on. If users are working, PerfectDisk will run in the background. With StealthPatrol, users can choose to have PerfectDisk only run during system idle time.
Minimal Free Space Requirement
Raxco Software pioneered defragmentation of the largest drives with minimal free space - as little as 1% free space on a drive is required to defragment it with PerfectDisk 2008.
Complete NTFS Metadata File Defragmentation
Because only PerfectDisk 2008 defragments all metadata, the result is a drive that is completely defragmented. Other defragmenters do not defragment all of the NTFS metadata and even more alarming, do not report on the files they leave fragmented. And PerfectDisk also provides complete fragmentation statistics for all files. You get the complete picture of the state of your drive. With other defragmenters, since you don't have statistics on all files, you're only seeing part of the picture.
Optimized Master File Table (MFT) Placement
PerfectDisk 2008 provides a 5%-10% performance improvement over typical defragmenters because of where PerfectDisk 8 places the MFT. Microsoft has specific guidelines for placement of the MFT for this improved performance, and only PerfectDisk follows these guidelines.
Selected Files Defrag
PerfectDisk 2008 allows users to defragment a single file, or selected files, rather than an entire drive if desired. This can be useful for users working with large files, such as videos.
CPU and I/O Throttling
PerfectDisk 2008 provides the ability to control CPU and I/O resources. While PerfectDisk 2008 uses very little CPU resources, administrators still have the ability to throttle CPU depending on certain circumstances. Similarly, I/O activity can also be throttled. This can be useful if, for example, another application is performing large amounts of I/O.
User-defined thresholds
PerfectDisk 2008's exclusive Perfect-Time? user-defined threshold capability allows you to limit the amount of times PerfectDisk needs to run to only when a site-defined level of fragmentation is reached, thereby reducing unnecessary defrag runs.
Full Active Directory Integration
PerfectDisk 2008 is fully integrated with Active Directory Group Policy Administrative Templates, allowing for comprehensive enterprise deployment, scheduling and management. This saves time with enterprise deployment and requires no training for administrators familiar with Microsoft's Active Directory.
Optional GUI-less Installation
PerfectDisk 2008 can be installed without the user interface active, giving administrators increased control. This allows administrators to deny end users access to the PerfectDisk interface if they wish.
Full-featured Command Line Interface
Full-featured command line support for both local and remote operations is provided. Command line support is not limited to certain commands, as with typical defragmenters. The ability to utilize all PerfectDisk 2008 commands provides administrators with even more control and allows for greater tailoring to your site's specific requirements.
Low System Resource Usage
PerfectDisk 2008 has low CPU and memory usage, which saves computer resources, freeing them for other needs and applications.
Automatic Shutdown After Defrag
PerfectDisk 2008 can be set to shut down at the conclusion of a defrag.
Defragments directories, pagefile and hibernate file
No file or directory is left fragmented with PerfectDisk 2008, so you'll have better performance. No other defragmenter defragments the hibernate file.
