I am running Windows 8 on an SSD, and it's all running swimmingly, but I want to store documents on two HHDs (not SDDs) running under RAID 1.

My motherboard has two SATA controllers, both set to AHCI. On the 3GB/s controller, all four ports are used (1 Bluray Optical Drive, 1 Spare HD, and the 2 I wish to turn into a RAID 1 drive). Windows is on the 6GB/s controller.

Like so:

enter image description here

So my question is:

If I turn these four ports (on the 3GB/s controller) into a RAID controller, will that negatively affect the non-RAID hardware plugged into it? I.e. Will the HDD or Bluray drive be slower/incompatible with being plugged into a non-AHCI controller?

Thanks.
