    HGST (formerly Hitachi Global Storage Technologies and now a Western Digital company) today announced a new helium-filled hard disk drive (HDD) platform, which is at the forefront of advanced technology for increasing capacity and significantly reducing total cost of ownership (TCO) for enterprise and cloud customers.

    With products expected in 2013, the new platform enables HGST to go beyond its award-winning five-platter design, providing a path for higher capacity storage and lower customer TCO for years to come. With industry-wide challenges in scaling current areal density technologies, this new platform allows HGST to design seven-platter drives in a standard 3.5-inch form factor that will cost-effectively extend the capacity and cost-per-gigabyte curve for many product generations to come. In addition, the inherent benefits of the platform, including the helium fill, allow HGST to significantly improve datacentre TCO on virtually every level: capacity, power, cooling and storage density.

    New Platform for Reducing TCO
    With the explosion of data resulting from mobile devices, Internet services, social media and business applications, corporate, cloud and big data customers are constantly looking for ways to improve their storage infrastructure costs and their bottom line. Also, new storage models, such as cold storage, are evolving in ways that require enormous amounts of data to be stored and available within a moment's notice. These hyperscale datacentres must deploy massive amounts of storage with the best TCO to help them manage their costs and growing storage needs. And when it comes to TCO, numbers matter most – cost-per-terabyte, watt-per-TB, TB-per-system weight and TB-per-square foot.

    The density of helium is one-seventh that of air, delivering significant advantages to HGST's sealed-drive platform. The lower density means dramatically less drag force acting on the spinning disk stack so that mechanical power into the motor is substantially reduced. The lower helium density also means that the fluid flow forces buffeting the disks and the arms, which position the heads over the data tracks, are substantially reduced allowing for disks to be placed closer together (i.e., seven disks in the same enclosure) and to place data tracks closer together (i.e., allowing continued scaling in data density). The lower shear forces and more efficient thermal conduction of helium also mean the drive will run cooler and will emit less acoustic noise.

    "The benefits of operating a HDD with helium fill have been known for a long time. The breakthrough is in the product and process design, which seals the helium inside the HDD enclosure cost effectively in high-volume manufacturing," said Steve Campbell, chief technology officer at HGST. "We are excited about the introduction of this platform, which demonstrates HGST technology leadership and is the result of more than six years of development in materials science, mechanical engineering and process technology. Thanks to the hard work of our research and engineering teams, our initial pilot lines are up and operational, putting HGST in position to introduce this technology first into the market."

    "As a technology innovator, HGST continues to invest in multiple R&D efforts that will help us win new customers, gain deeper market penetration and deliver a significant return on investment for our customers," said Mike Cordano, president of HGST. "Our new breakthrough platform delivers unprecedented innovation with new features optimised to meet the performance, scalability, efficiency and TCO demands of both corporate and cloud datacentres, which could not be achieved using conventional techniques. With these improvements, customer interest has been positive and we look forward to qualifying our new drives in 2013."

    The new, helium-filled sealed-drive platform is being demonstrated today at the Western Digital Investor event in Irvine, California. At the event, HGST is comparing the power consumption between a helium-filled drive and an equivalent air-filled drive side-by-side, demonstrating a reduction in power consumption for the helium-filled drive of 23 percent. Taking into account the extra capacity coming from two additional disks, the improvement in watts-per-TB is 45 percent. In addition to consuming less power, the drive operates four degrees Celsius cooler, requiring less cooling in the system rack and data centre. This reduction in power and associated cooling cost significantly contributes to the lower TCO of the helium-filled platform. The critical watt-per-TB metric will further improve over time as the helium-filled drive platform enables significantly higher drive capacities in future product generations.

    HGST will release specific capacities points and product specifications when the platform launches in 2013.

    This means also liter HDDs?? :))

    Hmmm. Never even thought less dense air would make a difference to platters on a HDD, but the bernoulli principles all take into account density for compressable and non-compressable fluids.

    That equates to lower shear forces on the air inside the drive, at the layer of the spinning disks, so less energy to spin. Brilliant. Just have to make sure the drive is completely sealed.

    Even so, but isn't actually better with complete vacuum inside?

    Nice, 7TB hard drives!

    Laptops would really need bigger HDDs, the current 7mm 500GB and 9mm 1TB is just not enough for many customers.

    Was thinking that too, or even a partial vaccum. Two problems that come to mind:

    • Making a vacuum tight seal would be expensive. Put helium in at atmospheric pressure, and you don't need much in the way of a seal.
    • I think the hard drive heads still need air to float above the media.

    Helium fillings...
    Surely, this means future HDDs will be squeakier than ever before?

    but then you have a pressure differential, which makes things really complicated. the units would constantly want to implode.

    Yay, now they can really jack helium prices when it runs out.

    Helium reserves are being decimated b/c the largest holder of them (the US) is forcing sale of it (and dirt cheap). It cannot be made (in case anyone didn't know LOL).

    It's not like it's important for cooling in advanced, high tech machines or anything. Lets put it all into balloons! Idiots.
