According to the following diagram, the Zacate APU has 1 on-chip PCI-e x4 interface. The Sapphire PURE Fusion mini-itx board has one mini-pci-e x1 slot, and one PCI-e 16x slot. My first question is; which of these slots is handled by the Hudson controller. My second question is; would an SSD connected to the on-board PCI-e interface likely perform better than a SATA III drive that interfaces with the Hudson controller?

Yes, such an SSD could be faster as PCIe x4 gives 1 or 2 GB/sec in full duplex (depending on if it's v1.1 or v2.0) compared to ~600 MB/sec for 6 Gbps SATA.
