Western Digital is shipping 12 TB helium-filled hard disk drives containing eight 1.5 TB platters:
Western Digital on Wednesday announced that it had begun to ship its HGST Ultrastar He12 hard drives with 12 TB of capacity. The HDDs are the first drives to employ eight platters, so the fact that Western Digital is now shipping them is important not only for its datacenter customers who need massive storage capacities, but also because the drive represents a significant step forward from a technology point of view.
The HGST Ultrastar He12 is based on Western Digital's fourth-generation HelioSeal technology, which uses eight perpendicular magnetic recording platters with 1.5 TB capacity each. To add the eighth platter, Western Digital had to redesign internal components of its HDDs (including arms and heads) significantly. In addition, the company increased areal density of the platters, which improved the sequential read/write performance of the new hard drives. In particular, Western Digital claims that the HGST Ultrastar He12 has a sustained transfer rate of 255 MB/s, an average latency of 4.16 ms, as well as an average seek time of around 8 ms.

How long does it take for the tiny Helium atoms to leak out
My first thought on reading the headline was a semi-sarcastic "What could possibly go wrong?"
Upon further reflection, I came up with a semi-serious "What could possibly go right with that approach?"
But, hey, they have been in the data storage r&d business for decades, so they know more about the situation than I.

Yeah. Though unlike you and I, they don't want the drive to last longer than the warranty period.
Money is not free speech. Elections should not be auctions.
