There is always ONE principle which guide my implementations: protect the data with the minimum amount of down time.

I get that by using two different RAID Setups. I have added a patch to my OS before and had to reinstall the entire OS.

With my RAID 5 array, I have both hot swap & hot spare. The array automatically brings the hot spare online and sends me an email to let me know a drive has failed.

I can restore my OS to my last Friday Image in less than an hour. I can protect my data by using my raid 5 Array.

I get want I need, speed for the OS and protection for the data.
