Because DMA isn't enabled; your dmactl is 0.  Try
	echo dma on >/dev/sdE0/ctl
and then rerun your benchmark.

As I understand it, DMA is enabled automatically only on controllers
found by pcimatch that are also known to have working DMA.  Anything
looks like a legacy controller won't have DMA enabled automatically.
