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.

Helium not so new for storage devices

Back in the early 1970's I programmed on a Varian 620F computer that had helium purged drum storage. The .25 meg drum had a sealed dome over the device and a helium supply attached. We had to replace the small helium bottle when the pressure got low. Appears that some are slow to catch up???

Neah, they just had to test the thing thoroughly. This being an enterprise-class product and all.

I assume the trick here was to produce HDDs that work without a pressure refill system? I don't think you still end up cheaper than an SSD if you keep buying and replacing bottles of Helium.
