What's Hot: Diskeeper comes in several different versions: Diskeeper 2007 Home, Diskeeper 2007 Professional, and Diskeeper 2007 Pro Premier. All three versions come with Diskeeper’s “Invisitasking” technology, which allows Diskeeper to run in the background without the need for a scheduler. This "set it and forget it" feature is the cornerstone of what makes Diskeeper such an outstanding product. Invisitasking ensures that your hard drives are always kept at optimal performance, but doesn’t affect system performance while it’s running because it only defragments files and programs that aren’t being used. If you prefer to have Diskeeper only run at certain times, then the program is flexible enough so that you can enable automatic defragmentation and set it to run on specific dates and times.
The Professional version offers a few more features than the home version, such as Automatic Directory Consolidation, Boot-Time Defragmentation, and FragShield. Automatic Directory Consolidation allows Diskeeper to move all the directories on your hard drive to a single location on the volume. Moving all of the directories to a single location will increase the speed of file searching. FragShield, another proprietary feature of Diskeeper, helps to guard against the fragmentation of your operating system files, which in turn increases the performance of your system. When Boot-Time Defragmentation is enabled, Diskeeper can defragment paging files and the Master File Table (MFT). Since this can’t be done while the files are in use, Diskeeper will defragment the files the next time you boot your system, when Windows isn’t using them.
The final version, Pro Premiere, has all of the features of the Professional version, but it also includes Diskeeper’s “I-FAAST” 2.0 (Intelligent File Access Acceleration Sequencing Technology). I-FAAST monitors which files and programs you use the most and then reorganizes those files to give you faster access.
The Professional and Pro Premiere versions also have support for 64-bit operating systems, and all three versions have the ability to disable background defragmentation when you’re using a laptop on battery power.
The Home version and Professional versions only support a 768 GB volume, while the Pro Premiere version will defragment a hard drive up to 2 TB, so if you have larger hard drives, you’ll need Diskeeper Pro Premiere. All versions will support a wide range of disk subsystems such as Primary Partitions, Extended Partitions, Logical Drives, Volume Sets, RAID Arrays (hardware and software), Mirrored Disks, and Mounted Volumes (letter-less drives).
What's Not: Noise. Depending on your system and the type of hard drives you have, all that background defragmenting can get a little noisy as your hard drives are constantly working. I’m not 100 percent certain that this constant use of the drive is good for its lifespan, but I’ve never read anything that says it’s a bad thing. For the increase in performance, I can live with a little extra noise.
Another thing I noticed about Diskeeper is that when I’m watching TV, using Windows Media Center, every so often the playback will pause for a second and then resume. This is especially noticeable when I’m watching a recorded show. It almost seems like Diskeeper is trying to defragment the file while I’m watching it, but I haven’t been able to verify that. I don’t see this same behavior if I’m watching a DVD movie.
Although this isn’t really a negative, it is worth mentioning: the Diskeeper Service acts as a server on your system, which allows it to support networking and remote control of the Diskeeper Administrator. This means that if you’re running any firewall software, you’ll need to make sure that you allow Diskeeper to run as a server and access the Internet if you have automatic updating enabled. If you’d rather not allow the access, then you can disable automatic updating and support for networking.
