Eh? RAID5 only causes heartbreak if two or more drives fail in quick succession. This is a slightly increased risk compared to simple mirroring -- where your heart only gets broken if the two failing drives are the two halves of the same mirror set -- but still a vastly decreased risk compared to JBOD operation. IMO the risk is close enough to zero that you'd have to search really hard to find someone whose RAID5 had failed in a situation where RAID6 or RAID1 would have saved the day.
