We are working from 2 or 3 machines. The lesser of the bunch is a MacBook Pro with 8GB of RAM with OS 10.7.5
Our media is stored on a few external hardrives, mostly G-Tech drives that are connected with firewire 800. Some are daisy-chained, others are plugged directly into the machine. (Actually, that would be the case for our more powerful tower. In the case of the macbook, all but one are daisy-chained.)
Thanks.
