Aren't you mixing metrics here? <div>&nbsp;</div> Miles per Gallon measures an effeciency ratio (amount of work done with a fixed amount of energy), not a speed ratio (distance traveled in a unit of time). <div>&nbsp;</div> Given that IOPs and MB/s are the unit of "work" a storage array does, wouldn't the MPG equivalent for storage be more like IOPs per Watt or MB/s per Watt? Or maybe just simply Megabytes Stored per Watt (a typical "green" measurement)? <div>&nbsp;</div> You appear to be intentionally avoiding the comparison of I/Os per Second and Megabytes per Second to Miles Per Hour? <div>&nbsp;</div> May I ask why?

BarryB,This is a great question, and decided my response was lengthy enough to justify its own post, which you can find here:<div>&nbsp;</div>
