Auslogics Disk Defrag:

Auslogics Disk Defrag is apparently a very serious product- no-thrills, no-frills. The product offers basic defragmentation features in a simple and slender way. One of its major features is the VSS (Volume Shadow Copy Service) mode, where the software prevents excessive changes made to the shadow files during adjustment of bits within the disk. There is a free version of Auslogics Disk Defrag, but you can also purchase a subscription for $29.95 which will keep the application up-do-date.

MyDefrag:

Formerly known as JkDefrag, the first impressions of this software should certainly be a scrambled-difficult piece of app. But if you notice it closely, you will understand that this software has managed to pack some really good features into it. Apart from the standard defragmentation process, there is a special choice for defragging an SSD. MyDefrag is free.
