I've done some fairly extensive testing, and it appears there is no performance advantage from using an emulated SATA controller over an IDE one, when using the above configuration.
The reason for the existence of the SATA controller emulation is (I assume) to have a high-performance storage option rather than for compatibility reasons, so I assume it's intended there should be a performance improvement when switching to emulated SATA.
