1TB Hard Drive






Features

  • 1TB capacity
  • Dual Processor
  • RAFF: Enhanced RAFF technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration in real time.
  • Dual Actuator Technology: A head positioning system with two actuators that improves positional accuracy over the data track(s).
  • Stable Trac: The motion shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations.
  • IntelliSeek: Calculates optimum seek speeds to lower power consumption, noise, and vibration.
  • Multi-axis shock sensor: Automatically detects the subtlest shock events and compensates to protect the data.
  • RAID-specific, time-limited error recovery (TLER): Prevents drive fallout caused by the extended hard drive error-recovery processes
  • No Touch ramp load technology: The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit.
  • Thermal extended burn-in-test: Each drive is put through extended burn-in test with thermal cycling to ensure reliable operation.
  • Third generation dynamic fly height: Each read-write head's fly height is adjusted in real time for optimum reliability.
  • 24/7 reliability: With 1.2 million hours MTBF (tested at 100% duty cycle), these drives have the highest available reliability rating on a high capacity drive.
