I'm editing a feature length film on my Imac (2 Ghz Intel Core Duo, 1GB SDRAM). I've got about 30 minutes of footage logged so far and it seems to be slowing me down a bit already. I'm looking into the G-Raid 500GB external hard drive (see http://dvcreators.net/g-raid-hard-drives) Was wondering if anyone has any experience with these? Is the G-Raid fast enough to work off of? I'd love to keep my entire movie project on the G-Raid seperate from my other computer stuff. I don't know if this is possible though(or smart). Any help is appreciated.
