To be fair I wasn't sure how it was acquired, a friend told me a few months ago and when I seen the post I found this BBC News - Helium shortage prompts scientist's balloon use warning "It is usually mined as a by-product of natural gas extraction. But resources are finite and demand is increasing, which is why supplies are restricted". But on a lighter note, I had never heard of the advantages of helium in hard drives, sounds good, will it be expensive?
Probably very expensive. I think at first we will just see them in use in servers in big data centers. They take up less space (per byte) and draw less power.
