HE10 10TB HARD DRIVE delivers the world’s first hermetically sealed, helium hard drive, the He10 for massive scale-out environments. Why does helium make a difference? Helium has only one-seventh the density of air. Replacing air with helium inside a hard drive dramatically reduces the turbulence caused by the spinning disks, cuts power consumption and results in a lower temperature within the disk drive. The reduction in turbulence for the spinning disk allows HGST to deliver a seven-disk design in a traditional 3.5-inch form factor. In addition to being the world’s first helium-filled hard drive, He10 is also the first hard drive in the industry 10-terabyte capacity. This design provides a 50% capacity gain and still reduces the energy needed to run the drive by up to 23%. Key Advantages/Highlights World’s first helium-filled hard drive Industry-first 10TB capacity in a standard 3.5-inch form factor TCOptimized design delivers on key elements of data center TCO: capacity, power, cooling and storage density SATA 6Gb/s models for configuration flexibility Self-Encrypting Drive (SED) options for HDD-level data security Applications/Environments High-density data centers Massive scale-out data centers Containerized data centers Nearline storage applications Bulkstorage Enterprise and data center applications where density and capacity are paramount Backup system Desktop PC
