HGST has come up with a way to pack more punch into data centre storage by stuffing its hard-disk drives with helium. The Western Digital subsidiary has started shipping the 6TB Ultrastar He6, a high-capacity drive that it claimed is considerably faster, cooler and more power-efficient than normal HDDs. Unlike standard HDDs, which contain five platters rotating in filtered air, the Ultrastar He6 uses helium, which is less resistant, lighter and cooler than air. The reduced friction and temperature mean disks can spin for longer on less power – allowing HGST to pack in seven platters and increase storage to 6TB from the usual 4TB. Since the drives shouldn't experience the same wear and tear as standard HDDs, HGST claimed its devices will last longer and therefore cost less in the long run, although the company hasn't revealed prices yet.
