Ultrastar hard drives feature up to 10 times the workload rating of desktop drives and
employ advanced technologies for enterprise-class reliability, power efficiency and
performance. Designed from the ground up to be an ultra-robust storage device, Ultrastar
drives are the perfect solution for your business.
High Workload Rating
Delivering dependable performance to any storage environment, Ultrastar hard drives
are designed with a workload rating up to 550TB per year*, among the highest of any
3.5-inch hard drive.
Enterprise-class Storage to Rely On
Ultrastar is our top-end drive for data centers. With up to 2.5 million hours MTBF,
Ultrastar hard drives deliver reliability and durability, are built for yearly operation
(24×7×365) within the most demanding storage environments, and are backed with a
5-year limited warranty.
HelioSeal® Technology
Featured in over 30 million Western Digital hard drives shipped**, HelioSeal technology
allows for higher capacities and lower power on large storage arrays. And now on its
5th generation design, HelioSeal technology is field-tested and proven to deliver high
capacity, reliability, and power efficiency you can trust. HelioSeal is a key technology on
10TB capacities and above.
Vibration Protection
Enhanced Rotational Vibration Safeguard (RVS) technology uses sophisticated
electronics to monitor the drive and correct linear and rotational vibrations in real
time for improved performance versus traditional desktop drives in high-vibration
environments.
Dynamic Fly-height Technology
Each read-write head’s fly height is adjusted in real time to ensure consistent
performance for reduced errors and optimized reliability.
Dual-stage Actuator Technology
Ultrastar drives feature a dual-stage actuator head positioning system for a high degree
of accuracy. The primary stage provides course displacement while the secondary
stage uses piezoelectric motion to fine tune the head positioning to a higher degree of
precision.
Compatibility testing
All Ultrastar hard drives are extensively tested across a variety of popular OEM storage
systems, SATA controllers, and host bus adapters to ensure ease of integration for a plug
and play solution.
7200RPM-Class
This family of 7200RPM-class hard drives delivers the fastest performance with the
highest workload rating of any drive in Western Digital’s hard drive lineup. Ensure you
have the most capable hard drive regardless of the application with Ultrastar hard
drives.
*Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is
annualized (TB transferred X (8760 / recorded power-on hours). Workload Rate will vary depending on your
hardware and software components and configurations.
** As of July 2018.
*** As used for storage capacity, one gigabyte (GB) = billion bytes and one terabyte (TB) = one trillion bytes. Total
accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) =
1,048,576 bytes. As used for transfer rate or interface, megabyte per second (MB/s) = one million bytes per second,
and gigabit per second (Gb/s) = one billion bits per second. Effective maximum SATA 6 Gb/s transfer rate calculated
according to the Serial ATA specification published by the SATA-IO organization as of the date of this specification
sheet. Visit www.sata-io.org for details.
