I will end my contribution to this particular topic with some of my favourite quotes from "Think & Grow Rich".
"Those who are afraid of new ideas are doomed before they start".
"Without doubt, the most common weakness of all human beings is the habit of leaving their minds open to the negative influence of other people."
"MAN'S ONLY LIMITATION, within reason, LIES IN HIS DEVELOPMENT AND USE OF HIS IMAGINATION."
I guess if someone can imagine a single unit drive with built-in redundancy, and they have the resources and capital to make it into a reality, they'd be called a pioneer. Until then, they're just plain KRAZY!!
