I just made the plunge into firewire recording, just ordered a 16 channel firewire mixer. I am really nervous about the latency issue, I had a standalone unit which does not have that problem. How do I go about connecting a external firewire hard drive and the interface together on a laptop? Most recommend an external drive for recording. Do you connect the drive to the second port on the firewire interface, or do you need two ports on the computer? Any help would be greatly appreciated.
