Are you really sure the onboard Sil SATA controller supports SATA II? When I studied the handbook of both motherboards, the A8N-SLI Deluxe and A8N-SLI Premium I found both motherboards are idetically equipted with the *not* SATA II capable SilI3114 SATA controller. By the way, as I know, the second SATA controller is attached via the PCI32 bus, not via PCIe! That means (in my opinion) there is no benefit using this controller. It is more a marketing GAG than a serious add-on. RAID5 performance of ICH7R and SilI is said to be very, very poor (about 10 MB/s read/write performance), so what benefit I do have using this controller with it's senseless 'capabilities' and non-PCIe attachment? This is only a thought based on my personal available informations and maybe wrong ...
