I have what seems to me like an odd issue. If anyone can help it would be greatly appreciated. I've been googling all morning trying to figure this one out.
sda = wd raptor 36gb 10k rpm 8mb cache
sdb = wd SATA 120gb 7200rpm 8mb cache
sdc = seagate PATA 160gb 7200rpm 2mb cache
here are the hdparm infos

When I run cached and buffered tests, the 10k Sata(sda)drive performs slower than the 7200rpm IDE(sdc).
The 10k drive has The OS on it, and the other drives are backup. Could this be causing the difference I'm seeing?
The IDE drive is newer and came out of a **rectTV DVR. What could be the difference there, that makes it perform better than the Raptor? Ares there any settings to change for the Raptor with sdparm to get better performance?
Here are the test results:
