FYI rtfm means "read the f-ing manual"...
Which I
did and didn't see it specifically mention any benefits of the NForce4 or the Sil SATA (there are 4 ports on each). The manual is available online:
http://america.giga-byte.com/M.../manual_k8nxpsli_e.pdf ... if
you see something in it I missed let me know. Not a very nice answer to what I thought was an intelligent question (and my first post here).
Page 11 (and again on page 26) tells the say the NForce 4 boasts 300 MB/s vs 150 on the Sil but since SATA drives are 150 that doesn't matter.
I was thinking possibly since the NForce 4 controls a lot of other things that it might be more efficient to use the Sil one - which is why I asked.... Was hoping maybe someone did some tests or something.
