Diskeeper 2011 Professional edition provides essential performance and efficiency increases that all business desktops and laptops need to function productively. Diskeeper prevents the majority of fragmentation (scattered file fragments randomly placed across the hard drive) before it can happen and instantly defrags the rest. More importantly, Diskeeper 2011 brings data flow up to peak speed for the best possible productivity.New IntelliWrite fragmentation prevention technologyIntelliWrite is the only technology that can prevent fragmentation on thin provisioned disks without requiring movement of any data and consequent increases in thin provisioned storage. IntelliWrite provides the benefit of a largely fragment-free OS file system without any negative consequences for thin provisioned storage, thus providing a peak performance level.New! InvisiTaskingThis exclusive technology can now use more idle resources faster for background optimization routines on even the busiest systems – with absolutely no intrusion on active system resources.NEW! Instant Defrag engineFor the first time ever, no newly fragmented files can slow performance, because Instant Defrag immediately defrags those files before they can be read. Instant Defrag is a new intelligence that understands how your files are used and ensures they never have to be read in fragments. Combined with IntelliWrite, every system runs at peak performance 24/7 regardless of workload. No system has ever been able to do this before!NEW! Efficient ModeIn addition to an extensive defragmentation mode, Efficient Mode offers the greatest net gain in system I/O resource savings ever available. It is smart enough to know what fragmentation is a problem and immediately targets and eliminates only fragmentation that directly affects system performance.NEW! Free space consolidation engineThis new and advanced engine swiftly consolidates free space and tightly integrates with Instant Defrag to handle new fragmentation as soon as it is created.Intelligent File Access Acceleration Sequencing Technology(Intelligent File Access Acceleration Sequencing Technology) improves file access and creation an average 10%-20% beyond the benefits gained with defragmentation alone, by optimizing placement of your most frequently accessed data.
