HGST Ultrastar™ 7K4000 is the world’s
first 4TB 7200 RPM hard drive with a 2.0 million hours MTBF
specification and backed by a full 1-year warranty, originally offered
with SATA 6Gb/s and now also available with a SAS interface. Ultrastar
7K4000 represents the sixth-generation HGST 5-platter design, which has
been field proven by top server and storage OEMs and Internet giants.
Engineered for the highest quality, the Ultrastar 7K4000 is put through
grueling design tests during development and must pass stringent ongoing
reliability testing during manufacturing. Ultrastar 7K4000 delivers by
reducing downtime, eliminating service calls and minimizing TCO.
Doubling the capacity density
As data center professionals across the
globe work to meet growing enterprise needs, they face the dilemma of
storing more data in the same footprint while also reducing power and
HVAC consumption. The new Ultrastar™ 7K4000 provides twice the data
storage capacity of the prior generation Ultrastar 7K3000 drive, and
does so using fewer watts.
Combining 7200 RPM performance and
granular power control
Operating at 7200 RPM, the Hitachi
Ultrastar 7K4000 offers better overall performance than slower-RPM,
capacity-oriented drives at impressively low power-consumption rates.
When compared to the previous generation Ultrastar 7K3000 , the 7K4000
offers up to a 155% improvement in sustained data transfer rate, and a
120% improvement in watts-per-GB. With five Advanced Power Management
modes, a 36% reduction in watts during low-RPM idle mode, and using less
than 1W during standby/sleep mode, the Ultrastar 7K4000 can help data
centers achieve lower AC power and HVAC requirements, freeing up
precious headroom
Enhancing data safety and security
To ensure the utmost in data safety and
security, the Ultrastar 7K4000 is also available with a bulk data
encryption (BDE) option. When enabled, the Hitachi BDE implementation
encrypts all data on the drive using a private security key as it is
written to the disk, and then decrypts it with the key as it is
retrieved, giving users an extreme level of data protection. Unlike
softwarebased encryption solutions, the Hitachi BDE implementation is
hardware-based, so it doesn’t slow the system down. This technology also
speeds up and simplifies the drive re-deployment and decommissioning
process. By deleting the encryption key, the data is rendered
unreadable, thereby eliminating the need for time-consuming,
multi-pattern data overwrite
Delivering industry-leading reliability
With a robust fourth-generation mechanical
design, Ultrastar 7K4000 is specifically built and tested for the
enterprise. The Ultrastar SATA drive family features Hitachi-patented
Rotational Vibration Safeguard (RVS) sensor technology, which optimizes
drive reliability in multi-drive RAID arrays and rack-mounted systems.
Backed by a one-year warranty, the Ultrastar platform has earned Hitachi
a reputation among server and storage vendors as a global partner
dedicated to delivering the highest quality and reliability in the
industry.
