Isn't helium guaranteed to leak out over time because of the tiny atom size, giving these drives a most certain scheduled death?

Isn't helium guaranteed to leak out over time because of the tiny atom size, giving these drives a most certain scheduled death?
- Retra 11y agoHelium diffusion is probably negligible next to the likelihood of puncturing the assembly or breakdown via normal use.
- ars 11y agoThe helium is not under pressure, it should not leak much. A metal to metal seal should do a pretty good job of sealing it, especially with no pressure.
- ScottBurson 11y ago"Guaranteed" is too strong a word, but I'm sure that engineering a seal that would hold reliably for years and could be mass-produced was a nontrivial problem. This is why everyone isn't already using helium.
