Description

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 efficiency of storage. To address this data center
challenge, HGST introduces Ultra star 7K6000, delivering up to 6TB of capacity
in an industry-standard, 3.5-inch hard drive, for capacity-optimized
enterprise applications. Ultra star 7K6000 provides 50% more capacity and 30%
better power efficiency in terms of Watts per terabyte (W/TB) than its
predecessor, Ultra star 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. Technology Innovation Improves
Storage Efficiency. Ultra star 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. Ultra star
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.
