No it isn't. Hard drives already exist and there is a history of them being made smaller, faster and less expensive. In order for advancements in technology to proof that evolution is true, you must first assume that macro evolution is true in the first place. The reality is that there currently is no proof that it is true.
BTW, natural selection is widely accepted, so advancements in technology would have little to add to the debate on evolution. It is macro-evolution that is the issue.
It is pretty much certain that evolution of creatures over millions of generations will be testable in the future. We won't have to wait millions of years.
