I am considering buying a G-raid 2 T hard drive. Sold here, hooks up by firewire. My system is adequate for video editing, P4, 3g processor, 2g ram, etc. It cannot currently handle the HD video I take with my Sony HD camera. If I purchase this hard drive, will it be able to handle the video processing without any other changes to my system? I don't quite understand the striping or mirroring of raid, and wonder if I'll still have to do that in my system if I same the video to this hard drive. I'm real green at the HD stuff. Any help?
