One thing you need to do is run with a faster bus speed. Unless you
are running a 75MHz bus, which you probably aren't, then you are
running a 60MHz bus (with 30MHz PCI bus). This means you are losing
10% of your potential bus bandwidth.
You shouldn't have bought a 150 in the first place. But since you
already have the chip, you need to see if you can overclock it to
166MHz (66MHz bus x 2.5, rather than 60MHz bus x 2.5, which you are
running now). Alternatively, you could attempt to run your chip at 2
x 75MHz, but most motherboards don't support this, and some PCI cards
might not like it either (that is higher than the "supported" bus
speed for the PCI bus).
It's possible you might even get better performance at 133MHz (66MHz x
2, rather than your current 60MHz x 2.5), if 166MHz doesn't work
reliably.
This advice goes along with other advice people are giving (like more
drives striped across more controllers, etc.).
