Why helium-filled hard drives outperform traditional HDDs

Air is traditionally used as a filling medium in hard drives. However, because of its higher density, it creates resistance, which increases energy consumption and puts more strain on the mechanical components. This is an issue in hard drives that pack in a lot of data since it can slow things down. Helium, though, is way less dense than air (about seven times less), so there's a lot less resistance. That means the parts inside don't have to work as hard, it uses less power, and the drive lasts ...
