This system is definitely too old for AHCI to be a chipset option.
You could always add in a cheap SATA card with Silicon Image chip, the sili
driver supports NCQ...
1-3MB/sec isn't near the max speed of any of your hardware, and you fail to
mention what you are doing while iostat is running to show this. What is the
problem again?

"...of course....In the end, Goldstein implies that "the war" might not exist;
the Oceanian populace know the external world solely via the Party's
propaganda, and that the rocket bombings, ostensibly by "the enemy", might be
self-inflicted (as Julia suggests), therefore, "the war" is a lie. Moreover, it
might possibly be that Eurasia and Eastasia are fabrications, and that Oceania
is the sole world power. In such ambiguity is the meaning of perpetual war:
internal subjugation disguised as defence against foreign subjugation, the
theory and practice of oligarchical collectivism..."
- 1984, George Orwell
