Hi Everyone,

I'm hoping someone can help me with this one. I've googled a lot, but haven't found a viable solution there. I'll be short.

I have gotten a new PC, coming up with a WD1002FAEX HDD. At some points it looked like it's choking so I did some tests.
The read speed drops sometimes to a "fascinating" 1 MB/sec.

In the same time I added a secondary HDD, my Samsung HD103SJ from my old PC, and that one didn't drop under 90MB/sec!

The WD HDD has been formatted around 2 months ago. I even defragmented the partitions. The WD should be far better than my Samsung! What can be the cause for this ?

Appreciate any help you can give me :) 

Thank you!
