    Default Don't let them float away

    W-D just announced their new line of 3.5" 7-platter disk drives that are helium-filled.

    No kidding.

    They claim higher performance, higher capacity, lower power consumption, lighter weight, and lower cost.

    I don't know if they have a tap to let you fill balloons or not.

    So the problem is turbulence, which is solved by using a lighter gas. That's very interesting.

    I wonder if sealing the drive and keeping a vacuum inside would work even better.

    Wonder why they didn't go with hydrogen, which is a good heat conductor. Hydrogen is used in some (most?) big power station alternators, or so I read in the Times.

    Too flammable.

    Picky Picky. And not if sealed.

    One reason, but a hint of worse things for your data. Hydrogen isn't inert and the flammability betrays its willingness to hang out with any of the transition metals. Granted, it is at temperatures much higher than those inside the computer, but who wants lonely hydrogen atoms seeking to bond with the metal on the platter when you can have something that is guaranteed not to be so promiscuous? At the density they're talking, I think there's a very real possibility of affecting data integrity.

    Western Digital and its peers are struggling to find cheaper and larger alternatives to SSDs. The article is correct, companies are beginning to move toward using SSDs in diverse locations as opposed to large RAID systems. This is going to leave WD with spinny things no one wants.

    We use SSDs in large RAID systems. They're fast, they're quiet, but they still fail.

    Flash! The new "Hindenberg" disk drive, hydrogen-filled, with a "lighting port" on the left side.

    Lighter optional.

    Talking of hydrogen and airships ...

    How would you like to be operating a spark transmitter on a hydrogen airship during WW1?
