These have been out for a little while now be seeing an article on a new Toshiba FC-MAMR HDD I recalled the first thing I thought of when this idea first came out; isn't there a looming shortage of helium on the horizon, if so, isn't it better reserved for it's cooling applications rather than filling up balloons and HDDs?

There'd be no helium shortage if someone could prevent Ben Shapiro from using it.

That's probably close to reality Hermit, with regards to helium-filled HD ;)

Never heard of it, partly because my needs are satisfied with SSDs, but from what I gathered helium in the drives allows for lower resistance and more plates. In ballons it just makes them fly.

Yes, that's also what I understood as the reasoning for adding helium to drives. These days all drives at home for me are SSDs, many of them nvme. I assume the main reason for sticking with spinning platters is capacity?
