use the gray/white sata ports fro SSHD and HDD and the blue for DVD etc
the gray ate SATA 3 while the blue are SATA 2
I currentlky do have the HDD plugged into the grey and the ODD, the SSHD is not plugged in right now. I am very sure I did not have the HDD plugged into the blue at any point I only plugged it into the 2nd grey port. Could it possibly be a sata cable I used that wasn't as fast as the original one I had. I am using the original SATA cable now though.
