> Capacity keeps increasing while performance remains darn near constant, The recent capacity increases seem to be mostly driven by stuffing more platters in, so as long as they don't have independently servoed heads (used to be a thing, maybe it becomes a thing again? Perhaps not fully independent, but still "ganged up" with some sort of micromechanics in each head to servo it to nearby tracks?) or increase data density (bits/cm^2), throughput must plateau.
