Helium filled hard drive reduces temperature in more

Western Digital subsidiary HGST has unveiled an interesting new enterprise-class hard drive series. The new Ultrastar He hard drives and are the first to be hermetically sealed and filled with helium. The drives offer 6 TB of capacity and have been qualified by some of the biggest companies in the tech world including Netflix, HP, and a number of social media companies.

"With ever-increasing pressures on corporate and cloud data centers to improve storage efficiencies and reduce costs, HGST is at the forefront delivering a revolutionary new solution that significantly improves data center TCO on virtually every level – capacity, power, cooling and storage density – all in the same 3.5-inch form factor," said Brendan Collins, vice president of product marketing, HGST.

The reason the drives are filled with helium is to reduce turbulence inside the hard drive associated with normal air. The helium used inside the drive is 1/7 of the density of normal room air allowing for lower power consumption and lower operating temperature inside the drive.

HGST says that the 6 TB drive uses 5.3 watts of power at idle, weighs 640 g, and runs 4-5°C cooler than a standard 3.5-inch five platter 4 TB hard drive. The drive also uses the HGST 7Stac design to reach 6 TB making it the highest capacity hard drive with the best total cost of ownership for cloud storage and other enterprise uses.

No, sadly Omega is correct, helium is non renewable; it is permanently lost to space once released into the atmosphere and can not be recycled. The natural sources of it are found with certain types of natural gas deposits, so there is quite a lot left to mine. But once it's gone, it's gone for good, and we'll never get more naturally from the planet.

I've worked with liquid helium for keeping super conductive magnets cool enough to remain so. Nothing can replace helium is certain types of research. So, yeah, it is a little silly for a HDD to be using such a precious resource, but as others point out, as the price of helium goes up, devices like these will disappear. Besides, maybe one day we'll be able to effectively fuse hydrogen to make helium as a byproduct; then it won't matter.

Oil and natural gas are non renewable as well and nobody gives a rats about burning and wasting them, why should helium be any different.The main source of helium I was thinking of was concentrated in large quantities under the American Great Plains, still supplying 90% of the worlds production, we have a new plant here in Australia making it as well. Using it in Hard Drives seems a good thing when compared to party balloons, then again party balloons wouldn't be much fun without it.

No one cares about the burning of oil and natural gas? Care to tell that to the growing amount of "peak oil" advocates?

Additionally, oil and natural gas are fully renewable. They can be produced by the break down of any biological source -- the more carbon rich and digestable, the more economically viable. There's also quite a bit of research suggesting some forms of oil are renewably produced by tectonic activity of the earth (i.e. geologically rather than biologically).

Technically Helium can be recycled but the low cost of using the reserves outweighs the hassle of recycling the gas provided it hasn't been lost into space.

Maybe somewhere in the near future there will be advancements to help maintain our current He supply or generate more from other sources more readily.

Maybe DT (not DailyTech) fusion?

A helium "children balloon" would use more helium than a couple dozens hard drives.
