    You can glean a lot from the Tom's Hardware 2.5" HDD charts. These results should let you compare some HDDs of the same family but with different capacities.

    There are also various benchmark results posted in threads in this forum.

    I don't think the size of the drive will have a noticeable effect on the performance. The same model of drive should perform the same at 160GB and 200GB, given a certain RPM speed.

    I looked up on hitachi.com, there are two 160GB's, the 200GB has a faster,
    Media Transfer Rate 160GB 695 Mb/sec max. 200GB 876 Mb/sec max.
    Latency and seek are the same. Here is a Link

    I am afraid you can not say that, because of the possible difference in data density.

    Thanks. That confirms it: Areal density 132 Gb/sq. inch vs. 164 Gb/sq. inch

    Most hard drives are designed in a way, where the 160GB version has the same density as the 200GB version. But why the difference in capacity?
    Its simple, to make production easier, they use the same disks. The hard drive capactity is what you are paying for. The 160GB drive hass 200GB of storage, it is just that the manufacturers limit the head movement, so that they can sell multiple sizes of the same exact hard drive.

    Usually you have to look at th number of disks to tell if their is a difference in hard drive actual size.
