Hard drive unusual slow.

[Joakim-h]

Hello!
I'll start off by a short presentation
My name is Joakim, just signed up.
and so far the site is great
And as my first post I have a question to the community.
2 days ago I bought a new hard drive for my computer.
It's a "Western Digital Caviar Green 1,5TB".
Found here: http://www.netonnet.se/art/dator/datorkomponenter/intern-harddisk/sata-3_5-tum/WesternDigitalCaviarGreen15TBSATA2/127087.4053/

Installation for the hard drive went good.
Installed Windows 7 32bit afterwards.
The real problem was when I started to transfer stuff to the harddrive.
it noticed how unusual slow it was.
The wierd thing is that it starts of transfering fast but goes down to around 10mb/s-30mb/s after a short time (this is the speed it continues to transfer at the rest of the timeline).

I took some screenshots aswell:

slow speed:

I am not sure on how I am going to fix this so I am very thankful for answers!
Best regards Joakim

EDIT:
I did not post that much information for eg. my computer due to the fact that I do not know what kind of information you need
So if you guys need any information just ask and I'll do my best to get it.

(sorry for double post)

Green drives sacrifice performance for power savings.

Green drives sacrifice performance for power savings.

isn't there anyway to change that and make it faster?

Not that I know of. Western Digital's black line of drives are their performance drives. The blue line of drives is their mainstream drive. The green drives are energy saving drives.

Yeah I understand that it is a energy saving drive.
But come on, right now im transfering at 11.4mb/s that just can't be right.

If you're transferring a bunch of small to medium size files your speed will be lower. In your pics it shows you're moving 36 files. Try moving one large file (like an iso file) and see what the transfer rate is.
