Western Digital , HGST expect helium-filled HDDs to get more popular this year

How the hell do they keep the Helium inside, the HDDs for an extended time. One of the most common problems with Helium storage its that it can slip through even metal bottles.

Producing a hard drive sealed in a helium environment was an enormous challenge. Why? Helium atoms are so small that they can seep through almost any material. Creating a case that will contain helium over a long period of time was the most difficult part of producing the drive - and the reason why helium drives did not go into use a long time ago. 

The tightly-sealed case produces a few more advantages. Humidity, dust and other contaminants are kept out. This is expected to reduce drive failure rates and increase the average life expectancy of the helium drive. 

The helium hard drive is an example of how using special materials creates special challenges but can result in exceptional savings.

I Guess its only natural they didnt say exactly, this technique could make them, loads of money.
