    ...OK, maybe not. I doubt even one is in my price range any time soon.

    would have thought nitrogen was a better gas to use, but then whatta i kno?

    That would just be pure air. Helium is lighter so less drag.

    it`s just that all my optics (camera lenses, riflescopes) are purged with nitrogen to displace water vapour, i sort of just dragged that across.
    of course, my glass doesn`t have any sort of drag coefficient to consider- nitrogen is cheaper as well tho`, which is probs why they use it.

    I wonder if they could create vacuum sealed drives.

    Helium because its smaller, lighter and hugely less reactive than Nitrogen.

    The heads fly over the platters on a cushion of gas, so the drive needs some gas in there. You could try low pressure air (or low pressure pure nitrogen would be slightly better) but a big pressure difference with the outside world is going to be harder to seal against. Helium at atmospheric pressure is quite a nice solution really.
