    first, determine if you need SATA or IDE

    get 7200rpm. higher RPMs = faster access times

    the larger the cache, the more it can store/transmit to the system. how big is the diff? barely noticeable.

    I recommend Seagate or Western Digital brands

    i've heard good and bad things about seagate.. i prefer WD

    if it is SATA, make sure the HD has a 3.0Gb/s transfer rate. if your computer only supports 1.5Gb/s it will slow down to that.

    the difference between 16MB and 32MB cache isn't very large, but don't go below 16MB.

    and yeah.. always 7200rpm.

    and no reason to get less than 7200 rpm for a desktop machine. at least no reason I am aware of.

    which is why i think this 'going green' thing of HDD manufacturers are stupid

    take WD's Green drives for example.
    it has variable speed, 5400rpm-7200rpm (it rarely use 7200rpm)
    power consumption, 4W-8W

    so basically,... what they did here is make the slowest part of your system runs slower,... just to save power, which is not even that power hungry in the first place. :ugh2:

    for laptops, sure.
    desktops,... that's just :greddy:

    Well, it would be a good idea to benchmark a "green" drive against a regular drive and see if there's any meaningful performance difference, before shitting a brick about it.

    I wanted to try out one of the 10k rpm raptors, does the extra 2800 rpm make much of a difference?

    these drives runs cooler and are dead silent,... great for HTPCs

    yes. windows alone will boot faster.

    the big question is if that difference is worth the price tag

    and btw, velociraptors > raptors

    It improves seek time, but the data is spaced too far apart for the extra speed to substantially improve file transfers compared to a slower drive with more tightly-packed data. It's the number of bits passing under the reader every second that determines file transfer speed, not how fast the disk spins.

    That being said, the new Velociraptors have almost the same data density as bigger, slower drives, plus they spin faster, so they should scream along pretty well.

    I have a 10k RPM 150GB Raptor, and I've noticed something interesting between XP and Vista: when I had XP installed, it was really fast and really quiet, but with Vista it sounds like a jackhammer. It's still very fast, but it must be something with the way Vista caches/prefetches data. Definitely not the choice for the noise-conscious Vista user.

    Superfetch sounds like a game you'd play with a genetically-engineered flying dog.
