Helping the world harness the power of data, HGST, a Western Digital company (NASDAQ: WDC) today announced the first enterprise-class 10TB (terabyte) hard disk drive (HDD) for next-generation active archive applications. The host-managed Ultrastar Archive Ha10 SMR HDD sets a new standard in enabling the world's densest server and storage systems with unprecedented TCO levels. This industry-defining product is the result of combining two complementary technologies - HGST's second generation, field-proven HelioSeal platform and shingled magnetic recording (SMR) - to deliver unmatched storage density and power efficiency, without compromising reliability and performance predictability. With an industry-leading 10TB capacity, the Ultrastar Archive Ha10 gives customers a time-to-market capacity advantage for archival environments and applications where data is sequentially written and randomly read, such as social media, cloud storage, online backup, life sciences as well as media and entertainment.

HGST recognizes SMR as core technology necessary in driving areal density increases. By overlapping or "shingling" the data tracks on top of each other, higher areal density can be achieved within the same physical footprint. Based on feedback from customers whose data center environments demand predictable performance and control of how data is handled, HGST has implemented a host-managed SMR solution. The sequential write behavior of host-managed SMR complements active archive workloads.
