Lian Li IB-01 - dubious claims?

I'm somewhat dubious about the claims that this card makes. It says that it has 5 x SATA II ports (presumably all running at 3 Gbps). But I was under the impression that a PCI-E x1 slot could only provide enough bandwidth for up to 2 sata ports on a controller card - any more and you need at least a x4 PCI-E slot. Five SATA II ports in a x1 slot? My guess would be that it can't run all 5 ports at 3 Gbps and would switch down to 1.5 Gbps. Can anyone confirm this?

Secondary question: would it possible to use this without using the RAID functions, i.e. simply to add extra SATA ports? I'd rather not span data across an array, but keep each hard drive discrete. But I do need extra SATA ports, unless someone knows of a motherboard with 12 of them?

Finally, I just realised that this card has 5 internal ports and 1 external port - but the product literature mentions nothing about the external port. Is it e-SATA? Regular SATA? Does the stated 5 ports mean 5 internal OR 4 internal and 1 external?

It's not dubious....

What types of ports and maximum performance are two different things. For example, current onboard ICH10R has 6 SATA 3GB/s ports... that would mean it would need to provide ~1.2GB/s of bandwidth. However, the controller can only provide 600-800MB/s.

You do not need to enable RAID.

From the pictures, there are 5 internal SATA and 1 external eSATA.
