Since this is a SCSI-only system I can't test ATA raid. :-)
I'm currently testing with prime stripe sizes, but it doesn't seem to
help. I additionally added "options AHC_ALLOW_MEMIO" to the kernel, and it
has raised write performance in the single-disk case (although I'm not
happy with that one either; I expected a disk on a U160 controller to pump
out more than ~65MB/s).
