Hi guys, I just purchased a new Nehalem 2.66 mac pro. I was looking to add internal drives that would allow for HD editing in FCP. I understand I have to configure a RAID. What level would be most efficient for editing video? Someone recommended a Raid 5 to me. Which formats could this handle? As high as DVCProHD? XDcam? How about HDCam compressed to ProRes? Any info would be greatly appreciated! Thank you!
