Which translates to the fact that storage vendors oversold hardware. Anyone can go fast if they buy a Ferrari.

The relevant question is not what did the now disgraced financial services firms due squandering their money (thus they are now being bailed out by taxpayers) but rather how responsible companies, spending their money wisely, can get adequate performance for reasonable dollars.

You can not write the same byte 3 times and get performance identical with a system that only write them twice any more than you can drive you car three miles on two miles worth of petrol. Physics doesn't subscribe to marketing hyperbole and DBAs shouldn't either.
