Hi. Soon to be getting into video editing and am looking at options for storage. Im on an iMac (640GB HDD), so will be needing an external drive for the storage of video. I am looking at THIS product. it holds 2 HDDs and uses RAID 0. I am aware that if one drive goes, so will the other.. Let me explain my reasoning in doing this. Please correct me, or point me in the right direction if im way off. 1. iMac - To store project files (not video). I am backed up via another drive with Time Machine... Im gathering I can store the project file on the main OS drive, and the video files on a second disk?? (coming from audio, this is what i used to do) 2. DV Tapes - I will archive all original footage on DV tape. 3. External HDD - So I store all my captured video on this drive, and edit from here. So if I lose the external HDD. I still have the project files and DV. All I have to do is re-capture.... Is this correct?
