    Larger HDD mean slower speed cause of "more disc" to spin thru?

    Does performance suffer at all for large HDD because of the fact that there is more disc, and hence more of it to spin through to find data?

    For example, would there be any performance differences between a 60GB and a 100GB harddrive (both at 7200 rpm)?

    No. Performance actually increases sometimes because of increased density, the bits are closer together, so the disk has to spin less distance to read the same amount of data.

    Is there any commonality in highend notebooks (T60, Sony Vaio)? Do they tend to go the increased data density route or the more platters/heads route?

    If you look at benchmarks, the WD Raptor 150 GB actually is slightly faster than the 74 GB version.

    Sometimes you will notice that large laptop drives, like 160 GB ones, will only come in 5400 RPM speeds.
