For me the main reason is much lower CPU load when using SATA. I've toyed with geode machines, using the IDE or PCI->SATA busses makes quite a difference. The WB and a Geode are different beasts I know. But i'd hate dedicating one core just to safely read from the drive. I think performance itself is not really an issue. Most SiI SATA chips (and others) handle port multiplexing (PMP). So you can hook (and "see" in the OS) more than 1 drive to a single port, via an external e-Sata multi-drive bay. If the Quad's SATA implementation includes PMP this opens possibilities that USB doesn't really offer, like running ZFS.
