I recently had two issues in the last month with critical machines having their hard drives crash, causing very expensive downtime.

These are just industrial PCs running various HMI and Controls software. They are a headache to get back up running, having to completely reinstall all softwares.

I know little about RAID, and read the wiki page on it. Would a RAID 1 setup let me have a complete backup running constantly? If one of the two hard drives failed, would it not even notice and continue running?

I don't know that you could keep running, but you could get a replacement HDD and copy the image back over I believe. I'm sure Smash will be along shortly to set me straight :)

I set up my computer with a RAID 0 array for the main installation and a RAID 1 array to back the RAID 0's disk image up on. Haven't had to use the setup yet, my Raptors are holding steady for now.

Correct a RAID 1 is a mirror however you will only be able to remove a drive and have it run off the backup if you have a redundant RAID configuration.

The way we do it at work for patching is the same thing.

Stop all services, Pull the backup drive and patch.

Check the live drive to make sure patch completed without errors then push in backup drive, it will then update with the live drive and restart services.

So yes short answer it will depending on if you configure it that way with your RAID configuration / server configuration.
