High capacity nearline drive Massive capacity suit almost any highly-demanding datacenter, enterprise server, or cloud storage needs. Designed for high-intensity applications Designed to handle enormous workloads, it delivers both performance & reliability to any datacenter environment. Vibration protection Enhanced RAFF technology

Includes:: sophisticated electronics to monitor the drive & correct both linear & rotational vibration in real time. The result is a significant performance improvement in high vibration environments over desktop drives. Dual actuator technology A head positioning system with two actuators that improves positional accuracy over the data track. The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy. Stable Trac The motor shaft is secured at both ends to reduce system-induced vibration & stabilize platters for accurate tracking during read & write operations. Multi-axis shock sensor Automatically detects practically any subtle shock events & compensates to protect the data. Designed for quality & reliability With long-lasting MTBF, these drives ensure high-level reliability ratings for high-capacity enterprise storage needs. No Touch ramp load technology The recording head doesn't touch the disk media ensuring significantly less wear to the recording head & media as well as better drive protection in transit. Dynamic fly height technology The read-write head's fly height is adjusted in real time for optimum reliability. Power Loss Data Protection Upon power loss, the drive utilizes stored spindle energy to back up the HDD cache to on-board flash. This allows deeper write queues which boosts performance, while minimizing data loss / corruption such as write splices that can occur during unexpected power losses. Main Specifications
