Building a new data center and getting power takes years to double your capacity. Swapping out out a rack that is twice as fast takes very little time in comparison.

Huh? What does your statements have to do with what I’m saying?

I’m just pointing out changing it out at 5 years is likely cheaper than at 3 years.

		Depends at the rate of growth of the hardware. If your data center is full and fully booked, and hardware is doubling in speed every year it's cheaper to switch it out every couple of years.
