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.
