    What is an external drive?

    I can't think of a better subject line.

    Two weeks ago I purchased two Comstar 320GB USB external drives. I'm very happy, with Robocopy doing its job.

    I'm puzzled about the heat level; it is very low.
    If there is a spinning drive within the ventless enclosure, where's the heat?
    I'm used to a 300GB IDE drive on removable rails making enough heat to boil a kettle (almost).
    How come these two beauties are so cool?
    I've read threads on "spindown" for external drives, which suggests that there are real spinning rotational disks inside.
    Yet from the heat level alone I'd suspect that my 300GB drives were just rather large memory keys - 300GB on a chip, so to speak.

    Hi Chris,

    The Comstar 320GB USB external drive's specs include:
    <hr>Average Seek Time < 11ms
    Data Buffer 8MB <hr>
    giving a seek time that is way to slow for a RAM-based storage device and a data buffer that such a device wouldn't use.

    With modern technology, there's no reason a high-capacity drive should generate lots of heat.
    Cheers,

    Thanks Macropod.
    Since my post I have heard what I take to be a drive "spin up" - first turning down my music source and oiling the cat to eliminate all superfluous noise.
    I realise, too, looking at the photos, that the casing is the same shade of blue as one of my memory keys, which probably helped me to wonder if the drives were little (!) more than a scaled-up memory key.
