When you are looking for economical, high-capacity enterprise-class storage, look to the Ultrastar® 7K6000. Designed to handle workloads up to 550TB per year, it delivers the value and performance you need for data center storage. With outstanding random write and sequential performance, the Ultrastar 7K6000 delivers 6TB of capacity in a 3.5-inch form factor. Innovations like patented Rotational Vibration Safeguard (RVS) sensor technology optimize drive reliability in multi-drive RAID arrays and rack-mounted systems. Engineered for the highest quality, the Ultrastar 7K6000 passes stringent reliability testing. The ultra-reliable Ultrastar 7K6000 reduces downtime, eliminates service calls and minimizes TCO. Rely on the Ultrastar 7K6000 to deliver value and performance to the cost-sensitive data center.Increasing Capacity Density by 50%
As petabyte (PB) growth continues to increase at a rapid pace, corporate and cloud data centers are under extreme pressure to improve the e iciency of storage. To address this data center challenge, HGST introduces Ultrastar® 7K6000, delivering up to 6TB of capacity in an industry- standard, 3.5-inch hard drive, for capacity-optimized enterprise applications. Ultrastar 7K6000 provides 50% more capacity and 30% better power e iciency in terms of Watts per terabyte (W/TB) than its predecessor, Ultrastar 7K4000. The 7K6000 is designed for all traditional
and rapidly growing scale-out storage applications, including object, block and file storage architectures, providing huge capacity, fast 7,200 RPM performance and economical $/TB acquisition cost.
Technology Innovation Improves Storage Efficiency
Ultrastar 7K6000 also delivers greater storage e iciency through high performance, achieving
up to 3X higher random write performance, thanks to HGST media cache architecture, a disk- based caching technology, which provides a large non-volatile cache on the disk. Media
cache also allows for improved reliability and data integrity during unexpected power loss.
Other performance-enhancing features include higher areal density for 25% faster sequential performance vs. 7K4000, and a 128MB cache bu er. Designed to handle workloads up to 550TB per year, Ultrastar 7K6000 o ers a 12Gb/s SAS (6Gb/s SATA) interface for easy integration into high performance data centers. As drive capacities increase, so does the time required to recover a failed drive in a RAID configuration. Dramatically reduce RAID rebuild times and maintain system performance during the rebuild process with the new Rebuild Assist. Learn more in our Rebuild Assist technical brief. For legacy systems that require native 512 formatting, models are available at 4TB and 2TB capacity points.
Data Security with Trusted Quality, Reliability
Compliance and privacy requirements drive the need for increased data security. Ultrastar 7K6000 helps protect data from unauthorized use by o ering security and encryption options. Instant Secure Erase (ISE) models expedite drive redeployment and retirement. Encryption models protect data with hardware-based encryption, including a Trusted Computing Group (TCG) Enterprise_A, TCG with FIPS 140-2 certification, Level 2. The Ultrastar 7K6000 is a seventh generation, 5-platter design, field proven by top server and storage OEMs, and Internet giants, and extends HGST’s long-standing tradition of reliability leadership with a 2M-hour MTBF rating
