WD Releases World’s First 14TB Enterprise HDD

Today Western Digital Corp. (WDC), under its HGST brand, released the world’s first enterprise 14TB HDD, Ultrastar Hs14. The Hs14 is designed for cloud and hyperscale data centers that need more density. The Hs14 is host-managed, and leverages shingled magnetic recording (SMR) technology. Not only does the new Ultrastar drives deliver 40% more capacity, with its 14TB, WD states that it has more than twice the sequential write performance of its SMR predecessor.

Data is continuing to grow. The importance of being able to store this data to gain insights is also growing. While there are plenty of ultra-high density SSDs being announced, companies need to store the data now, and in a cost-effective method. The new Ultrastar Hs14 address both of these issues offering up to 14TB in a 3.5” form factor and online watt/TB power efficiency for extremely low TCO. The new HDD leverages two complimentary technologies: fourth generation HelioSeal technology, and second generation host-managed SMR. These technologies have been field-proven and are ideal for cloud, hyperscale environments, and ultra-dense scale-out storage systems running sequential write workloads.
