That sounds actually good to me... A while ago I read somewhere that we should start to treat hard drives more like tape drives: - disk capacity is increasing a lot, - disk transfer speeds are also increasing, but less compared to capacity, - disk latency (seek times) is improving very slowly. Hence currently it takes much longer to copy an average disk than it took a few years ago. And while raw transfer speeds are great, as soon as you need a seek, it degrades a lot.
