Very slow performance with WD 2.0 EARS drives

Greetings,

 

I'm running unraid on a Intel SS4200-E NAS box, and installed 2 WD 2.0TB EARS drives.. I did the following

 

1. Installed the 7-8 jumper on both drives before they were ever installed in the system

2. Ran pre-clear on both drives

3. configured one for parity and the other for data, unraid synced parity without any problems.

 

Problem is I'm only getting about 10MB/s read and write performance to the box. I have another homebuild NAS that I built from an old Linux box and it typically sees 40-60MB/s performance.  Both are on the same network, gigabyte ethernet, same client box used for testing.

 

Is there a step I missed with these EARS drives, or are they really just that bad?
