For my reply I meant boot not the OS. I use a separate raid 5 or 6 for
the OS with the raid 1 for the 256MB boot.

I thought more about this. While I like the idea, I have logging on and we
also have the database writing to the drives as well.
That was my primary reason for having the OS on separate drives, so that the
database writes do not interfere with the media writes.

The question I have is, would 6+ concurrent HD captures writing to the disks
run into any issues with the database writing to the same disks?

I do like the idea thou of boot being mirrored, OS being raid 5/6 and media
being a separate raid 5/6.
