I hate power outages. They kill more hardware than about anything, even lightning.
Let me go back to that example of 24x1TB drives, RAID 6 or RAID 10. It was mentioned that RAID 10 can only lose one drive without failing, whereas RAID 6 can lose two without failing. If this were politics, I would let that slide as party bias. However, if you want the statement to be factual, if not a bit redundant, what it should state is that a RAID 6 can lose as many as two, but no more than two, drives without failing, The RAID 10 can lose as few as one drive, or as many as 12 drives, without failing.
If you play the odds, you are not very likely to be lucky enough to lose 12 drives before failing but, you would likely get at least two, and possibly more. However, a guaranteed two sounds a whole lot better than *probably* more than one.
