Well, I think this can't really be the issue, because i took a few drives out and tested them individually in a windows workstation. (Pictures in my last post)

Well I've tried it with HD tune and HDD sentinel and the results are less than stellar... Write: Read: HDD sentinel thinks its fine:

I cant see any outstanding errors in smart either. cat /root/smart.txt |grep Multi_Zone_Error_Rate 200 Multi_Zone_Error_Rate 0x002a 100 100 000 Old_age Always - 31 200 Multi_Zone_Error_Rate 0x002a 100 100 000 Old_age Always - 6 200...

when i do a dd on a slower disk sometimes it goes down to 7MB/s according to gstat. I have no idea what could cause something like this. New cables, no issues according to smart, no apparent reason why is it so slow.
