Lower Capacity and Cost Effective for Smaller Data Sets and Legacy Applications

Data centers face growing pressures to manage costs. For affordable server boot drives, or applications that use smaller data sets, Western Digital offers the Ultrastar DC HA200 series, an entry-level, low capacity line of enterprise-class hard drives. Designed to handle workloads up to 550TB per year, the Ultrastar DC HA200 series delivers up to 2TB cost-effective storage capacity for data center environments. Rotational Vibration Safeguard (RVS) technology utilizes 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. Ultrastar DC HA200 series is offered with a SATA 6 Gb/s interface and native 512-byte (512n) sector size for compatibility with legacy data center applications.

- RVS anti-vibration technology for robust performance in multi-drive environments
- Reliable, field-proven design
- SATA 6 Gb/s with 512-byte (512n) supports legacy enterprise applications
- 2M hours MTBF rating and 5-year limited warranty
