Im not sure you have DMA enabled on your drives, which could cause you
all sorts of woes. For example, my timed cached reads on a 1.6ghz
machine are 1065 MB/sec. Let your box settle down a bit and then run
hdparm -d1 /dev/hdaWhatever
then run that hdparm -tT again

The place where you made your stand never mattered,
only that you were there... and still on your feet
