Ultrastar DC  HA210 (7K2)

Ultrastar DC HA210 (7K2)

2TB & 1TB
Enterprise Hard Drive
*Previously Ultrastar 7K2

  • High Capacity – Up to 2TB
  • Built for the Enterprise – Robust mechanical design
  • Legacy Compatibility – SATA with native 512 block size format

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. 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. 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.
