Defragger

I use the Auslogic defragger so is the a better one that you would recommend. Thanks

Honestly nothing. I would leave Windows to optimize the drive as it wishes particularly with SSD.

While defragmentation is required (particularly but not only on HDD) there doesn't seem to be much in the way of independent test results that indicates using some other software instead of windows optimization makes much of a difference.

From this rather old review

there are hardly any differences between the defragmenters. Significant differences can be observed only for the boot time and Civilization IV. Therefore, this is more of a list of "defragmenters that are only a little better than the Windows 7 Defragmenter":

Do you have some issue that makes you think additional defragmentation is required? If so do you use a HDD or SSD?
