How to spot a degraded SATA port on Intel 6-Series Motherboard: Use HDTune
 

A few members on our local forums already spotted degraded S-ATA II ports on the P67 boards, basically you just need to run HDTune and check the "Health" tab, bad boards will fail some tests but do OK if you move the drives on the S-ATA III ports.
