I also just ran IOmeter on the Windows guest again, against both IDE and SCSI emulation, against guest discs hosted on the mdraid5 with lvm, as well as a single SATA2 7500RPM disc. Identical results against both targets. 4096B blocks = 0.75MBps. 16KB blocks = 1.0MBps, 32KB blocks = 4MBps, >=64KB blocks = 4MBps. All tests 50/50 read/write, and run again 50/50 sequential/random.
