Ultrastar DC HA200 Series

Entry-Level Capacity Delivers Data Center Value


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.

One megabyte (MB) is equal to one million bytes, one gigabyte (GB) is equal to 1,000MB (one billion bytes), and one terabyte (TB) is equal to 1,000GB (one trillion bytes) when referring to storage capacity. Accessible capacity will vary from the stated capacity due to formatting, system software, and other factors. 


Portion of buffer capacity used for drive firmware. 


 1MiB = 1,048,576 bytes (220), 1MB = 1,000,000 bytes (106). 


 MTBF and AFR targets are based on a sample population and are estimated by statistical measurements and acceleration algorithms under median operating conditions. MTBF and AFR ratings do not predict an individual drive’s reliability and do not constitute a warranty.
