I wish that were true... I think you misread the same spec sheet I saw, which listed it (cleverly) as 10 in 10^16. The spec is indeed 1 in 10^15 as shown in their datasheet: http://www.hgst.com/tech/techlib.nsf...e/USHe6_ds.pdf

That helium-filling tech looks great, though. I hope they introduce it on smaller drives too.
