I understand that, but I never .. NEVER keep file where my OS is installed. never. Well, at least nothing I am not willing to lose. I have extra HDD's that will be keeping that stuff, so if I corrupt my OS install, its not a big deal to just reformat and go again.

I keep images of my fresh install as well, so I should be good to go.

Trust me, I work in IT. I have seen how unstable RAID setups can be, I come prepared with first hand experience.
