Auslogics Disk Defrag Ultimate Review

Overall, we rate Auslogics Disk Defrag Ultimate as an excellent, powerful defrag tool that comes with a host of advanced features. These features will give you a considerable amount of control over the defrag process, yet remain effective. Besides defragmenting your drive’s files, Disk Defrag offers you various optimization options that improve data access speed even further.

Auslogics Disk Defrag Ultimate provides multiple defrag algorithms to support your needs. For example, it can optimize access in four different ways, including optimization by:

  • File access time
  • Windows own prefetch layout
  • File modification (change) time
  • Disk Zone, which includes manually configuring which file types, or individual files, you want to be written fastest

It does all these while leaving some free space after defined files, which reduces the chances of future disk fragmentation. This lets the program significantly increase file access speed and makes anything you do on your PC work faster.

Auslogics Disk Defrag Ultimate Pros and Cons


The Disk Defrag Ultimate has new features that allow it to perform many functions including:

  • Defragmenting hard drives and locked system files.
  • It optimizes file placement on disks using four different optimization algorithms.
  • It consolidates free space to form a large contiguous block.
  • It has a fragmentation prevention algorithm to prevent future disk errors.
  • It allows the defragmentation of folders or single files.
  • It also has SSD, VSS, and compatible modes.
  • It can defragment disks automatically in the background.
  • It includes extensive scheduling options including the creation of multiple tasks.
  • It allows managing and monitoring the program-produced load on system resources.
  • It provides detailed system performance and defragmentation reports and graphs.

With many new features and improvements, Disk Defrag Ultimate remains fast and easy to use. It is the ideal tool for speeding hard disk drives and maintaining their performance.


Disk analysis using Auslogics Disk Defrag Ultimate takes only a few minutes. However, advanced disk-defrag operations can last for hours (between four and seven hours). The free space optimization requires PC restart for defrag to occur before Windows is loaded.

The free version of Auslogics Disk Defrag Ultimate is much less powerful. It doesn’t give you any choice of defrag algorithms, and there is no resource management or boot-time defrag. Its scheduling is more basic, and fragmentation prevention mode is missing. It also lacks performance charts and doesn’t show detailed reports, and there are no special algorithms for SSDs.
