reminds me of dialog in 'So I Married an Axe Murderer'...

Charlie: "For example, how many people have you brutally murdered?"

Harriet: "Brutal" is a very subjective word. What's brutal to one person
          might be reasonable to somebody else."

I think SATA hard drives are so cheap nowadays, that it's hard to
justify choosing RAID 5 for more yield at the cost of performance and
reliability.
