One of my PC have only Sata2 Intel Controller onbaord and the other PC have one 2 Port Marvel a little bit slow SATA3 Controller onboard and a lot of more Sata 2 Ports.
On the only SATA 2 PC i have an SATA 3.0 PCI-Express card for the SSD and all intel SATA 2 Ports run in IDE Compatible Mode.
On the SATA 2/3 PC i can choose wich port have AHCI and wich not. I choose SATA 3 yes and all SATA 2 no.
So in the Future when i buy a new Intel Board (Skylake or more Kaby lake or the Kabylake -X Chipset) or maybe is the same on all AMD Ryzen Boards… i read only SATA3 Ports… So of course when its only one Controller its AHCI then for SSds…
What did you do with these newer systems? When the optical drives dont work with AHCI`?
Running the mainboard controller on AHCI. Plug in other older non raid (SATA1/SATA2) cards for the optical drives without AHCI? And wich one?
Or did you choose IDE Compatible Mode if its still avaible and plugin SSDs and SATA3 HDDs on an extra Marvell, AS Media or something else SATA 3.0 Card?
I hope its the right forum here… if not move it pls on the normal hardware forum.
