WD Ultrastar DC HA Series Enterprise Data Center SATA HDD

Enterprise SATA Storage for Established Systems WD Ultrastar DC HA210 is designed for organisations that need dependable, continuous storage while maintaining established enterprise platforms. Its native 512-byte sectors and SATA connection make it particularly useful where a qualified system requires the original 512n format rather than an Advanced Format replacement. A 7200rpm spindle and enterprise workload rating support applications that need regular access to working data, backups or archived information. Built for multi-drive environments, HA210 combines vibration compensation, precise head positioning and RAID-specific error recovery. It suits compatible servers, storage arrays and enterprise NAS systems where the exact drive format, firmware and host qualification are as important as raw capacity. Highlights Integration with established platforms SATA 6Gb/s interface and native 512-byte sectors. Standard 3.5-inch internal drive format for supported storage bays. Designed for continuous workloads 7200rpm operation, 128MB buffer and typical sustained transfer up to 200MB/s. Designed for 24/7 availability and workloads up to 550TB per year. Features for managed storage Enhanced RAFF vibration compensation and a dual-stage actuator. RAID-specific time-limited error recovery and a five-year limited warranty. Key Features Native sectors for legacy application requirementsSome enterprise systems and applications are qualified around native 512-byte blocks. HA210 retains that sector format, helping administrators maintain a supported storage configuration when replacing or extending an established platform. Native 512n is different from 512e emulation and 4Kn formatting, so match the drive to the controller, operating system and application requirements before installation. Responsive access to enterprise dataA 7200rpm spindle, 128MB buffer and average rotational latency of 4.2ms support frequently accessed capacity storage. The SATA link provides a familiar connection to compatible host hardware. Its interface bandwidth and the drive's sustained media transfer rate describe different things; the complete system, access pattern and controller determine the performance delivered to an application. Vibration compensation for shared enclosuresSeveral drives operating in one chassis can expose each other to linear and rotational vibration. Enhanced RAFF monitors these disturbances and makes real-time corrections to help maintain read and write performance. This is useful in supported rack-mounted systems and multi-drive arrays, where good mounting, cooling and chassis design work alongside the drive's own compensation technology. Accurate head positioning and protective mechanicsThe dual-stage actuator improves positioning accuracy over the recording tracks. A multi-axis shock sensor and dynamic fly-height technology help the drive respond to operating disturbances, while ramp load/unload keeps the heads away from the media when appropriate. These features support reliable operation within the published environmental limits; careful handling and a properly installed drive remain important. Error recovery designed around RAID operationRAID-specific time-limited error recovery helps reduce drive fallout caused by extended internal recovery attempts. This allows a compatible RAID controller and the drive to work within the system's expected recovery behaviour. Use the controller manufacturer's supported drive and firmware guidance when building or maintaining an array, and retain independent backups of important information. Workload capability for continuous serviceHA210 is designed for round-the-clock availability and rated for workloads up to 550TB per year. It is suitable for qualified enterprise environments such as data warehousing, cloud storage, backup repositories and enterprise NAS. Include both application activity and maintenance operations when planning storage traffic, then provide adequate power, airflow and monitoring for the intended deployment. Clear reliability and support expectationsThe published two-million-hour MTBF and 0.44% annualised failure rate are statistical population estimates, rather than a prediction for an individual drive. A five-year limited warranty provides manufacturer coverage subject to applicable regional terms. Health monitoring, tested backups and a planned replacement process remain part of responsible operation throughout the system's service life. Summary WD Ultrastar DC HA210 combines native 512n compatibility with enterprise SATA performance and features for continuous multi-drive use. It is a practical option for maintaining qualified legacy platforms or building supported capacity storage around an established format. Confirm the exact drive against the host's compatibility requirements, then use the specifications to plan installation, power and environmental conditions. 더 보기
