But, I think the OP's real problem is that everything is tied to one single large drive (i.e. the software mirroring is mostly irrelevant as well as the controller type). These would get you a queue of outstanding commands compared to a SATA, but if you want a big difference in throughput or less latency when multitasking you really have to split things over a bunch of drives, either with some other type of raid or explicitly mounting different filesystems so you can control which things compete for the disk head position.
