Pros & Cons:

Very solid piece of software. Updated regularly. Now with S.M.A.R.T. monitoring.
No optimization feature yet.

Our Review:

Piriform's Defraggler—The first thing that caught my attention when first opening Defraggler was a green word, GOOD. I quickly realized it was telling me about S.M.A.R.T. Status (information provided by the disk itself, reporting temperature etc). This is a great feature and has its own tab on the program for detailed view.

In terms of defragmentation ability, Defraggler is one of the best choices you could make. It performs a very fast “quick defragmentation” with decent file reorganization but if you perform a complete defrag process, which takes longer, you obtain results that are worthwhile. Your files will be together as they should be as solid as a concrete wall.

Defraggler also supports scheduling, low priority and boot defrag. Highly recommended.

O yes - Defraggler allows an optimization … it's a simple defrag (just placing files is quick defrag there).
