Hey guys. I'm a new Mac User and Seasoned Video Editor who is switching from the PC world. Please be gentle on me. I just pulled the trigger on the new 2.66 Octo mac pro this morning. I need to figure out a couple of things that have been causing me major confusion. 1) How fast can I get the throughput on 4 1TB Hard Drives using OSX Leopard software Raid 0? Fast enough for 2 or more Streams of 35mbs a second HD XDCAM Footage at 60i? Link to camera here http://pro.jvc.com/prof/attributes/features.jsp?model_id=MDL101851&feature_id=01 (The reason for going OSX softraid is everyone keeps telling me internal hardware raid cards are now incompatible because of the new drive tray design. The 4 Drives I am going to be using are the WD RE3 1TB Drives) 2) Would 12gbs (2gb x 6 via OWC) of Ram be enough for Editing this kind of Footage in Final Cut Pro or Avid 3.5 in near real time? Any advice would be greatly appreciated as I have been living on the boards for the last two weeks trying to figure this out. Trying to get the most bang for the buck without taking out a loan. Unless necessary. I am Editing a Long form Documentary for a Non Profit group. Thanks.
