I have two 4G SCSI drives bound ^^^^^^^^^^^ 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.). ----------------------------------------------------------------------------- Michael L.
