Massive scale-out data centers (MSO)

As petabyte (PB) growth continues to increase at a rapid pace, corporate and cloud data

centers are under extreme pressure to improve the efficiency 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 efficiency 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, the fastest 7,200 RPM performance

and the best $/TB acquisition cost.

Ultrastar 7K6000 also delivers greater storage efficiency through best-in-class 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 buffer. The 7K6000

offers 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.

Compliance and privacy requirements drive the need for increased data security. Ultrastar

7K6000 helps protect data from unauthorized use by offering 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 and a 5-year limited warranty.
