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, timelimited 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.
