Helium Purifier for Sale, being seven times lighter than air, doesn’t cause as much turbulence. This allows the rotating discs to go up to 10,000 RPM without overheating. The Ultrastar He6 can, therefore, provide high input-output per second without losing efficiency, which is generally caused due to overheating.
With considerably reduced turbulence inside the drive, the rotating disks can be packed closer by up to 50%, giving these storage drives a higher storage capacity than a regular disk drive of the same size. HGST built the Ultrastar He6 on the regular 3.5-inch form factor but with a storage capacity of 6TB compared to the standard capacity of 4TB to highlight this space effectiveness.
Hitachi’s press release indicates that Helium drives can be submersed in water because they are sealed to trap Helium inside. This reduces the cooling costs even further since big data centers can simply use water for cooling the storage drives without having to use expensive helium purification system cooling techniques.
