RAID1 is simply two discs that mirror each other. When one drive dies, you get a message, and then you replace the dead drive (either 0 or 1). The good disc then rebuilds the new disc you put in, and you never stop functioning.
I got that message today, and for $80, I replaced a dead 160 GB drive. The firmware driven RAID driver simply rebuilt the new disc into a replica of the surviving disc, and I was interrupted only by the amount of time it took me to power down and put in a new disc. It was much better than getting a black screen with "No bootable media found."
Going further, I actually bought two new 160 GB drives figuring that if one was dead the other didn't have that much longer to go. So, after the system rebuilt one disc, I pulled out the good disc and replaced it with a new one. The system rebuilt that one, and I now have a backup sitting on a shelf in case the files get corrupted on one and mirrored to the other. I think I've got all my bases covered, but ya never know.
