Hi,
recently i was worried about my HD speed (specially when i try to play some games). My PC is:
CPU: AMD FX-8359 (8 cores, 4GHz)
RAM: 2x4 GB DDR
MB: Gigabyte 970A-DS3P
Graphic Card: AMD Radeon HD 7700 2GB
HD: WD10EZRX-00L4HB0 (1TB, SATA-III 6.0Gb/s).
I analyzed with defraggler and it said ~40% frag (314GB).
I left it working yesterday and this morning (it's still working) and i have 239GB left.
It's took about 16hours to rearrange 75GB... isn't it too slow? :/ It's normal?
Thanks
Before Defraggling you should first run CCleaner to remove unwanted files.
In Defraggler ensure all these are ticked ☑ . .
. . and defrag.
Follow with a Boot Time Defrag . . 
Alternatively I use file defrag. It's sohhhh fast. Tick ☑ Filename
and click Defrag Checked.
First, thanks for your response

I usually pass CCleaner
Very useful

It was marked.

I'll try

I'll start with this right now
Thanks
Edit: i see that my disk performance is “1.72 MB/s”. It’s fine?
Edit 2: After 75min with file defrag, 6% done. I guess it needs ~21h to complete :/
For me a file defrag usually takes only seconds, and rarely over one minute.
What percentage free space have you?
You could try also unticking HUGE FILES. They are probably not worth the time defragmenting them (unless they are pretty fragmented).

18.2 GB (20%). File defrag it's as slow as normal defrag :/ After 2 days, i still have 30% remaining.

Except 1 or 2 files, the biggest files i have are near 8GB, and not too many.
Anyway, i think my problem is not the time i need to defrag but the speed of my defrag. I read about defrag big disk in a few minutes, but a need a lot of hours :/
Edit: i found that my HD is "WD green", so it's "normal" to have low performance. But the HD's datasheet (http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-800026.pdf) says the average speed should be 175 MB/s.
With HD Speed (from steelbytes) i check it's true (at least, in the nearest areas of disk), but defraggler still says <2MB/s, and it's so slow.
I deleted a lot of files, and now i have ~45% disk free and 19% frag. After 4h (just with defraggler) i have 2k fragment less (9GB)
