anyone tried striping two G-SATA arrays on PCI-express G5?
A sales guy at GTECH told me I could connect two of their G-SATA arrays with a four-port adapter card, stripe the arrays and get increased performance over a single G-SATA array. I understand the theory behind all this, but given that the G-SATA arrays and the adapter cards are brand new for the PCI-Express G5’s, I’m wondering if anyone has yet done this in the real world.

That is correct.
It is no different than doing it on anything else. You should see between 50%-70% increase in throughput
when adding one additional drive and striping the 2 units together. However adding more than 2 drives to any single bus will not give you any more than about a 75% increase due to the limitations of the data bandwidth during transfers.and the same holds true for Firewire also.
