Auslogics Disk Defrag aims to speed up PCs suffering from fragmentation by defragmenting them. The program arranges the components of your hard disk / HDD files together. Since Windows Vista, Microsoft systems have been defragmenting automatically and, for the first time, quite efficiently when it comes to increasing performance. Defrag tools are therefore in a difficult position today. Auslogics Disk Defrag asserts itself with a variety of functions that give it a raison d’être.
In the past, Auslogics Disk Defrag was structured like an assistant, but the manufacturer has now abandoned this interface style. The visual appearance looks modern – as with many defragmenters that are updated. Is such a program still needed today? Despite many features and good designs, not necessarily: More and more PCs and notebooks are using an SSD. You should not defragment one of these, the optimization does not bring any speed gain; it promotes wear and tear and reduces the service life. Auslogics Disk Defrag makes sense, however, if you have an older PC only with a hard drive, whose performance you can lift into new spheres with the tool, depending on the degree of fragmentation. But the installation of an SSD brings more; cheap SATA models no longer cost around 100 euros. Even the best defragmented HDD is lagging behind a bad SSD in terms of speed. If you have an SSD computer in which an HDD (usually connected via SATA) is installed in addition to an SSD, Auslogics Disk Defrag also makes sense: You install the tuning tool on the SSD, then use it to treat the HDD drive.
We tried the SSD optimization with Auslogics Disk Defrag Ultimate, which currently costs 27.26 euros as much as Auslogics Disk Defrag Pro. The function should create a particularly low write load and thus be gentle on flash data carriers. The manufacturer does not reveal precise information about the algorithm. It is questionable whether SSDs need this tuning: The CrystalDiskInfo tool attested us a 9 gigabyte higher host write load after the (NVMe) SSD treatment. Yes, the write load is lower than with most conventional defragmentation programs. However, the fact that there is write access at all with the special optimization and that no advantages are evident from it speaks against this function.
Assessment of Auslogics Disk Defrag: Conclusion
With Auslogics Disk Defrag, you can get old hard drives in good shape, which you can do with ease thanks to the reliable operation. The SSD optimization is reserved for the Ultimate version and is a nice accessory for enthusiasts who have a good feeling about it. Technically, the SSD “improvement” is certainly not absolutely necessary; in the test it even created a write load that promotes wear (albeit marginally). SSD tuning in defragmenters seems to be all the rage – O&O and IObit implement something similar. Abelssoft and Ashampoo as tuning / defrag providers stated in statements for another article that they did not see any point in SSD defrags. Switching to Auslogics Disk Defrag in the paid Ultimate version is most worthwhile if you want to benefit from auto-defragmentation and offline defragmentation. The target group is small here, because at least you do not need the offline maintenance measures if Windows is installed on the SSD. On the other hand, the Ultimate Edition comes up with a more modern user interface and more settings, so you can choose how you use your PC (as a “workstation”, for “games” or as a “server”) and how often you use your PC during commissioning Documents and work on the Internet – the software adjusts the optimizations to your use.
The manufacturer offers another useful utility called Registry Defrag. This even makes sense when applied to SSDs (no defragmentation in the conventional sense) and closes the gap with Auslogics Disk Defrag Free, as it does not compress the registry database. If you combine both free applications, you don’t need to spend any money.
The pros and cons of Auslogics Disk Defrag:
+ Clear, modern interface + Successfully eliminated our test fragmentation + Optionally includes prefetch data in the optimization + Also defragments individual files + Insane configuration leeway with Ultimate + No web installer, installation offline possible; portable version can be created – Unclean installer (adware software with you; Auslogics Free) – Scheduler is idle (“Automatic defragmentation” is an ultimate function) – Compared to O&O Defrag, there are no defrag algorithms (Name, Access, Modified) – No free offline defragmentation
Alternatives: The freeware Smart Defrag also defragments and trims SSDs, with no harmful write load. Trimming SSDs makes sense. And / or you use the exclusive free full version Ashampoo WinOptimizer 18. Since the 18 version, the Defrag module has the ability to perform a “retrim” called trimming of SSDs.
