Poor performance on Sil 3132 controller on A8R32?

[Axbattler]

Hello,

I was just wondering if this is an isolated case, or a general issue with all A8R32 boards: the HD performance on my Raptor is atrocious when connected to the Sil 3132, but works fine on the ULi controllers.

This is disappointing to me, as I do need all 5 SATA connectors available, and it also make me question if the external SATA connector work properly (since it is driven by the Sil 3132 controller as well).

Thanks.
