Product Data Sheet

Value to the Data Center with Performance-optimized
Capacity for High-intensity Applications
Data centers that need fast access to data in Tier 2 environments need look no further. The
Ultrastar
®
DC HA210* HDD, a member of our HA200 series product line, delivers fast data
access in capacity-optimized, enterprise-class storage systems. Enhanced RAFF
™
technology
in the DC HA210 includes sophisticated electronics to monitor the drive and correct both
linear and rotational vibration disturbances in real time—especially helpful in multi-drive
arrays and rack-mounted systems maintaining high read/write performance. Designed
to handle workloads up to 550TB per year, the Ultrastar DC HA210 delivers up to 2TB of
affordable storage capacity for high-intensity applications in enterprise-class environments.
Maximize Your Data Center Application Investment
with Proven Storage Technology
Data centers face growing pressures to store more with flat-to-shrinking budgets.
Keeping systems operational for as long as possible to maximize investments can be an
effective part of the strategy, but supporting those legacy applications becomes even
more challenging as drive technologies move to next generation formats and interfaces.
The Ultrastar DC HA210 has a SATA 6Gb/s interface and native 512-byte (512n) sector
size to provide consistent, high performance and compatibility with legacy data center
applications. Dual-stage actuator technology provides a head positioning system that
improves positional accuracy over the data tracks, enabling data to be written to and read
from the drive more reliably. Trust Western Digital to deliver storage options that allow
data centers to get the most from their hardware investment.
Designed with Data Center Requirements in Mind
Multi-axis shock sensor technology automatically detects the smallest shock events and
compensates to protect stored data on the Ultrastar DC HA210. RAID-specific, time-
limited error recovery reduces drive fallout caused by extended hard drive error-recovery
processes. Ramp load/unload technology keeps the recording heads away from the disk
media during idle time and power down, ensuring significantly less wear to the recording
heads and media, and provides better drive protection in transit. Through the use of
dynamic fly-height technology, each read-write head’s fly-height is adjusted in real time for
optimum reliability and performance. With a 2M hour MTBF rating and a 5-year warranty,
rely on Ultrastar DC HA210 to deliver capacity, performance and reliability for more value
to your data center.
