I also bump on the same sentence about efficiency, just after the one about IT carbon emissions. Doesn’t computation usually use way more power than storage? This looks like journalist trying to oversell it, I hope it’s too lunch skepticism and there’s really something here.
- grishka 2y agoNonvolatile storage by definition doesn't use any energy to retain data after it's been written. But an HDD needs some to spin either way while it's on, even when it's not currently being accessed. I can kinda see where they're going though — if this discovery enables increased bit density on magnetic media, you need fewer HDDs to store the same amount of data, so they use less energy when they're on.
