Thanks for responses to my post. After testing my set up, it proves out that more firewire drives slow the firewire system. I didn’t know the 800 bus is connected with the 400 bus.
with only the G-Raid 2 plugged in it performs as advertised.
When more than one firewire is attached all the firewire drives suffer a performance loss.
I will be using the G-raid2 for transferring projects to another off site system so it still has value. For performance I have 3 internal drives striped in raid 0 and I get around 200 MB per second read and write.
