HDD vendor, HGST recently announced it is shipping the 6TB Ultrastar He6 hard disk drive. First revealed in September 2012, HGST’s HelioSeal platform provides a path for higher capacity storage for decades to come while significantly lowering customer total cost of ownership (TCO). The new Ultrastar He6 drive features HGST’s 7Stac™ disk design with 6TB, making it the world’s highest capacity HDD with the best TCO for cloud storage, massive scale-out environments, disk-to-disk backup, and replicated or RAID environments.
According to IDC, areal density growth rates have slowed, and are expected at a rate of less than 20 percent per year from 2011 to 2016. Moving forward, HGST’s helium platform will serve as the main platform for new technologies like shingled magnetic recording (SMR) and heat-assisted magnetic recording (HAMR) where HGST will continue to push the HDD areal density envelope. The helium platform will also serve as the future building block for new, growing market segments such as cold storage, a space that HGST plans to address over the next couple of years.
"HDD industry areal density growth is not keeping pace with the rate of storage capacity growth in enterprise data centres," said John Rydning, research vice president, IDC. "HGST's proprietary, new, hermetically sealed, helium-filled HDD solution – the industry's first helium filled platform that simultaneously increases capacity while lowering power consumption and operating temperature – is intersecting the market at a time when IT managers are seeking out capacious and energy efficient new disk drives that will help to reduce the total cost of ownership of enterprise storage systems."
