Hello.
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 ...

I have noticed the same thing with the onboard Silicon Image controller.
I am using the A8N-SLI Premium. I am using the Silicon Image controller
instead of the nForce4 controller because it specifically said SATAII
and said it supported RAID5 (whereas the nForce did not support RAID5).
However, on boot it recognizes it as SATA150 (which should be SATA300).

Hello.
I have a little question about the popular nForce4-SLI chipset for the
Socket 939 platform. The onboard SATA controller of the nForce4-SLI
chipset claims to be NCQ (or SATA II) capable, but nVidia implemented
this feature in a not-AHCI-standardised way, but as an own solution. My
question is: Is the FBSD 6.X driver for the nForce4-SLI chipset capable
of using NCQ (as I know, the driver has to enable NCQ and it's not done
automatically by the harddrive-controller interaction).
Thanks in advance,
Oliver
