    Atleast if the drive dies you suck in the helium and have a laugh :)

    I suspect the helium use for this product will be insignificant compares to others.

    At least it's a meaningful use of helium

    Seeing as the whole point is that helium is less dense than air, I don't see what's so odd about that, the reduction in density of the filling causes a greater reduction in mass than the increase caused by the additional two platters. That sounds quite plausible.

    Except the volume of gas in a typical HDD probably doesn't even account for 1g, my guess is it would be due to the reduction in the size of the motor along with the associated mechanics.

    Except the maths doesn't work out at all for that. Given that 50g of air itself takes up 38l or so of space (at 0°C and sea level), whereas an HDD's total volume (as in measured from the enclosure) is around 0.393l, replacing the air with helium wouldn't account for that. They simply made some weight saving changes elsewhere.

    EDIT: In fact, to save 50g on switching air with helium, you would have to swap approximately 46l of air with the same volume of helium.

    If you can keep the helium in, why not just run it under vacuum?

    I believe that's something to do with how the arm of the HDD itself rides on a small cushion of air so as not to scratch the platter.

    8 of these in RAID is a start.

    I'm ordering 20 of them as we speak.

    So what are you paying for them?
