Increasing SSD Capacity With the Help of Sound

Instead of using heat to support an increase in storage density, the researchers said they can target ultrasound waves at a "highly specific region" and hold a tiny region of a material to be bent or stretched. The advantage of sound is that its impact can be more easily contained while heat tends to spread beyond a target area.

"We’re near the peak of what we can do with the technology we now use for magnetic storage," said Pallavi Dhagat, an associate professor in the OSU School of Electrical Engineering and Computer Science. "There’s always a need for approaches that could store even more information in a smaller space, cost less and use less power." Dhagat said that sound waves could improve storage density in SSD devices.

"This technology should allow us to marry the benefits of solid state electronics with magnetic recording, and create non-volatile memory systems that store more data in less space, using less power," said Albrecht Jander, also an associate professor of electrical engineering working on the research.

There was no information on a working system using this technology, but hopefully it won't be long.

    Sound... What?

    CaptainTomSound... What?
    Here's a close-up of this new, experimental technology:

    Wondering if Mozart or The Beatles recordings work better :-)

    Uh, so millions of little speakers inside the device?

    I think the range of ultrasound that it produces is kinda important. I fear that this may be a dog's worst enemy...

    Just don't sneeze to hard near it, you might crash your system.

    Sometimes, youhave to edit links back in. The link "Read the comments on the forums" between the article and the comments section lets you edit your posts. You can give it a try from there.

    I don't see how sound is any more localised than heat to be honest. If anything, less so.

    This is possibly the STUPIDEST IDEA EVER!

    SSD's work by having millions of little "buckets" to hold electrons and the copper wires are a delivery system.

    How would a SOUND version of this work?
    There's really no way to have a main source that focuses sound at the scale they imply. It's also an added cost.

    Maybe I'm dead wrong, but I know how Hard Drives and SSD's work and can't even remotely picture how this would work.
