Their R&D is in the millions and you sit there in your room twiddling your thumbs seemed to have fingured it just wow!

Even small chances in resistance matter a lot when the drive has 4 or 5 platters spinning at over 5000 rpm.

Helium has been known to be a superior medium for a long time, the only advance they made recently is in how to product such drives cheaply

To spin the drive the energy required to overcome the moment of inertia will be far greater than overcoming air resistance, once it is spun up the only forces acting to slow it down are air resistance on the platters and friction in the bearings (which a very low friction fluid dynamic bearings these days), so your premise is wrong.

The fact that helium migrates through most metals and can cause helium embrittlement should be a bigger concern.

Could you explain, should we be concerned about this process when storing our data? And how rapid this process is?

As far i understand embrittlement this shouldn´t concern some sealed systems as are hard drives because they're in closed space for themselves and there even todays HDDs dislikes impacts that could stress magnetic layer. Only where this things should be of any mean are portables and somehow i believe that people are more and more willingly migrate to SSD 240GB+ even in next year. And ask god how big will ssd be when this drives see the light of the day. While in closed rack system there arent any movement only during setup/repair.

"Helium" embrittlement??? You'll have to explain that.

Seagate doubts viability of a new advance, there is a surprise. They did the same with SSDs.
