In the data center, every little bit that saves on cooling or power consumption helps, and to that end Western Digital’s HGST brand is shipping a new hard drive that’s designed for higher-capacity storage, higher storage density, lower power consumption, and lower cooling requirements. The HGST 6TB Ultrastar He6 features the company’s 7Stac disk design, claiming 50% higher capacity in a standard 3.5-inch form factor over competitive 5-platter, 4TB drives. As we first wrote about last year, though, the premier feature of the new HGST platform is that it’s filled with helium... Read more...
You may have heard of liquid nitrogen being used in computer cases, mostly for cooling and bragging, but what about helium? Not so much. However, Hitachi GST (HGST) has just introduced a new platform of helium-filled hard drives. The company states that these offer greater capacity and significantly reduce the total cost of ownership for corporate and cloud data-centers. But what of the helium itself? Well, the density of helium is one-seventh that of air. This lower density means dramatically less drag force acting on the spinning disk stack so that mechanical power into the motor is substantially... Read more...
