Best defragmentation (optimization) program

[Bouzoo]

So what is the best program for defragmentation (optimization in win 8 and 8.1) that you are using? And is the stock one in windows good enough or should I use some other one?

The widows one is fine. As long as your dirve is not fragmentated heavily the impact on performance in not that big.

Auslogic and Piriform Defraggler are both good.

The integrate windows tool is habitually good enough except under windows 7 but sometimes you need a great tool like Defraggler to do the job.

Start to try with the windows tool & then scan again to see if it's ok, if not then use Defraggler.

I've seen people recommend either Auslogic or Mydefrag, but usually on tests it seems Mydefrag is better even though more users recommend Auslogic. What's so special about it?
