As mentioned previously under the headings for DVSD and HD delivery, there are different disk speed bandwidth requirements and different ways to meet those challenges.
DV 3.6 MB/sec for one video stream and can be easily accommodated by one ATA or Serial ATA disk drive.
Can I use Firewire drives for video capture?
Apple has never qualified any Firewire drive for video capture whether it be one for DV or a FW RAID for SD. Yes, I know that lots of people use them or try to and loads of them get dropped frames on capture. (Final Cut Pro 4 User’s Manual: Volume 1; page 44)
What do I buy for video capture?
What about RAID?
