this new platform allows HGST to design seven-platter drives in a standard 3.5-inch form factor that will cost-effectively extend the capacity and cost-per-gigabyte curve, though HGST didn't state the expected capacities these can reach (estimate 6 TB plus).
HGST compared the power consumption between a helium-filled drive and an equivalent air-filled drive side-by-side, demonstrating a reduction in power consumption of 23 percent for the helium-filled drive. Taking into account the extra capacity coming from two additional disks, the improvement in watts-per-TB is estimated at around 45 percent. In addition, the drivers run four degrees Celsius cooler, which requires less cooling in system racks and data center.
