You could look into using a different fs depending on which one you use,
there was recently a benchmark of the various fs on lwn (iirc). Also the
new WDC Raptor 740GD SATA drives can do command queueing, but I am not
sure if the 3Ware SATA RAID Controllers support it yet. That combination
would probably be your best bang for buck. Of course if you need a large
raid you also need to make sure you have 64bit/66MHz pci slots, since
normal pci tops out at 133MB/s. I assume the cards work in 32bit slots
as well, but have never used them.
