What would be the Fstop value before the image gets bad?<HPX>

If you have RAID5 configured properly, losing one drive is not a problem. Just tell RAID5 to recover the bad drive (REBUILD) after you swap it out the bad one for a new drive. It does take time - but at least there is fault tolerance. To recover from two drives failure (really unlucky) - you need RAID 6. Performance of the RAID5 is pretty good.

BluRay drives and media is extremely expensive right now. I am waiting for prices to fall to the level of DVDs first. Wondering what happened to HD-DVD then?

TingSern,
The one had the problem was RAID0, so there's so much I can do. I've been selling RAID drives ever since Micronet started offering, so I know the technologies but I was never able to give up on the extra space and slower speed of real redundant levels because I could always go back to tape. My project files are saved separately. So the RAID drives are working as scratch drive for me before. But now, with P2, I don't have backup on tapes.

So, even with all of the experience I had, I could be skeptical about the backup and loose some footage. And Blu-ray is what I already have, had to get it anyway to accomodate the new DVD Studio Pro anyway, I'm going to utilize it for the sure backup method.

I spend numorous amount of time testing these things, having extra space and equipment to test the work flow and trying to figure out what is most safe and effective for my customers. Hard drives, you can mistakenly erase it. Blu-ray, the chances which loosing data is less by the misoperation on the computer.
