Auslogics Disk Defrag Pro aspires to replace the basic Windows defragmenter, offering useful features like Disk Zone and Free Zone optimizations. It has a very informative interface with all the options you need and includes statistics, reports, and scheduling, but it isn't the fastest of utilities.
Very customizable: Auslogics Disk Defrag Pro does not only standard defrag operations, but also lets you choose from different types of advanced defragmentation, use task scheduling, and check before and after results. It can handle SSD drives, as well.
Disk Zone and Free Zone optimization modes: Of all the available defrag modes, we liked these two the most, because they bring good improvements to slow and small drives typically found in laptops. Free Zone optimization released 3GB in a 90 percent full 2.5-inch 250GB disc, while Disk Zone optimization enhanced speed by cleverly positioning the more frequently used data in the faster disk surface areas.
Defrag times: While analysis takes only a few minutes and basic defrags allow you to run other apps without significant lag, more advanced defrag operations can last between four and seven hours. What's more, for the free space optimization, our computer had to be restarted for the defrag to take place before Windows loaded.
The well-featured Auslogics Disk Defrag Pro satisfies high defrag requirements, an improvement over the default Windows defragmentation app. Large 3.5-inch drives hardly need it, though, and will be fine with the default Windows utility. However, if you own smaller capacity 5400 RPM drives, then the $29.95 price tag makes sense.
Editors' note: This is a review of the trial version of Auslogics Disk Defrag Pro 4.3.8.
Auslogics Disk Defrag Pro is the professional edition of your favorite defragmenter. It is an essential PC optimization and maintenance utility, designed for maximizing hard drives' efficiency. The Pro version is now equipped with 4 different disk optimization algorithms for intelligent rearrangement of files on disks, and has an offline defragmentation engine for defragmenting locked system files (including MFT, Windows Registry, Paging and Hibernation files). This allows the program to significantly increase file access speed, meaning that just about anything you do on your PC will work faster. Those users who are not sure which optimization algorithm to choose, can take advantage of the program's Defragmentation Wizard. It will suggest the algorithms that best suit your computer usage style and schedule.
Here is a brief overview of the improved and new features that allow the program to speed up your PC and keep your hard drives in good shape: Defragments hard drives and locked system files; Consolidates free space into a large contiguous block; Optimizes file placement on disks (4 different optimization algorithms are available); Includes a fragmentation prevention algorithm; Allows defragmentation of single files or folders; Has SSD- and VSS-compatible modes; Can defragment disks automatically in the background; Has extensive scheduling options (including ability to create multiple tasks); Allows monitoring and managing the load on system resources produced by the program; Provides detailed defragmentation and system performance graphs and reports. What is important is that with so many improvements and new features, the professional edition remains just as fast and easy to use as its free version, making the program an ideal tool for speeding up and maintaining hard disk drives.
