Western Digital HGST Ships 6 Terabyte Helium-Filled Hard Drive
As we first wrote about last year, though, the premier feature of the new HGST platform is that it’s filled with helium (helium!). The Ultrastar He6 is hermetically sealed with HGST’s HelioSeal process and filled with helium instead of air. The company says that because helium is just one-seventh the density of air, there’s less drag on the spinning disks, and the reduced fluid flow allows for both disks and data tracks to be placed closer together, thereby enhancing the possible drive density and also reducing power requirements and noise.
HGST says that the drive boasts the lowest power consumption and best watts-per-TB on the market, besting the competition by 23% and 49%, respectively, and it’s even lighter in weight--about 38% lower weight-per-TB. The technology is slated for emerging tech such as shingled magnetic recording (SMR), heat-assisted magnetic recording (HAMR), and cold storage.
