Hdd problems

HDD Problems

  • Air filled hard drive problems

    • Memory space

    • Energy usage


Introduction

Introduction

  • Hitachi Global Storage Technologies (HGST)

  • HGST designed helium filled hard drives

  • Addresses these persistent problems


Helium

Helium

  • 2nd lightest element

    • Behind hydrogen (Lightest element)

    • Very good choice for hard drive

  • 23% of mass of universe

    • 2nd most abundant element in universe


More helium

More helium

  • However, not as abundant on earth in pure form

    • Gravity cannot keep helium in atmosphere

  • Found as component in natural gases in America

    • Compose up to 7.6% of these gases

  • Abundant enough for HGST to use in hard drives


Some numbers

Some Numbers

  • Increases hard drive storage capacity by 40%

  • Reduces power consumption by 23%


Benefits

benefits

  • Helium results in “less drag on the head arms and the spinning disk track”

    • http://www.gizmag.com/hgst-helium-filled-sealed-hard-drive/24190/

  • Less power is used to perform tasks like these

    • Moving and positioning heads over tracks


Benefits leading to benefits

Benefits leading to benefits

  • Less power and movement leads to something else

  • Results in data tracks and disks being placed closer together

  • All this means that they can store more data in the hard drives


More numbers

More numbers

  • Increases density within each disk with infusion of helium

  • Means each disk can store more data

  • Number of disks increases from 5 to 7

  • All within the 3.5 inch enclosure of hard drive


Security

security

  • Helium hard drive is hermetically sealed to keep helium in

  • Also keeps out contaminants

    • Dust, humidity, water etc.


Shhhhhhh

shhhhhhh

  • Helium hard drive run with more efficient thermal conduction

    • 4°C cooler than regular air

  • Means that helium hard drive runs much quieter than air filled hard drives


Table

table


Hgst figures it out

HGST Figures it out

  • Three things needed to be solved in order to design helium filled hard drive:

    • “How to build a drive structure stiff enough not to flex with pressure changes

    • How to seal in helium, a gas known for its remarkable diffusion properties

    • How to manufacture such drives in high volume at a competitive price”

      • http://www.zdnet.com/helium-filled-drives-announced-7000004222/


Interesting aspect

Interesting aspect

  • Gives us more capacity in our hard drives which will become more important in our lives

  • More energy efficient, which our generation needs to address

    • Becoming more “green”

  • Shows how advanced all aspects of technology are becoming


The future

The future

  • Helium filled hard drives set to realize in 2013

  • HGST hopes to revolutionize hard drive industry

  • Also wants to compete with main developers of hard drives
