Ultrastar 7K2

  • 2TB & 1TB
  • 3.5-inch
  • Enterprise Hard Drive
  • 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 7K2 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 7K2 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 7K2 delivers up to 2TB of affordable storage capacity for high-intensity applications in enterprise-class environments.

CAPACITY: One MB is equal to one million bytes, one GB is equal to one billion bytes and one TB equals 1,000GB (one trillion bytes) when referring to hard drive capacity. Accessible capacity will vary from the stated capacity due to formatting and partitioning of the hard drive, the computer’s operating system, and other factors.
MTBF/AFR: Specifications are based on a sample population and are estimated by statistical measurements and acceleration algorithms under typical operating conditions for this drive model. MTBF and AFR ratings do not predict an individual drive’s reliability and do not constitute a warranty.
BUFFER: Portion of buffer capacity used for drive firmware.
TRANSFER RATE: MiB/s is 1048576 (220) Bytes/sec, MB/s is 1000000 (106) Bytes/sec.
SEEK TIME: Excludes command overhead.
