Designed for data centers and demanding environments, WD Ultrastar drives have a MTBF rating of at least two million hours and are built for yearly (24x7x365) operation.

WD Ultrastar drives are built with Enhanced Rotational Safeguard (RVS) technology, which monitors and corrects linear and rotational vibrations in real-time for improved performance.

Dynamic Fly-Height technology utilizes real-time read/write head adjustments for consistent performance, reduced errors, and optimized reliability. Dual-Stage Actuator technology improves positional accuracy over the data track. The primary actuator provides course displacement using conventional methods, whereas the secondary actuator uses piezoelectric motion to fine-tune the head positioning to a higher degree of accuracy.

WD Ultrastar hard drives are extensively tested with a variety of storage systems, SATA controllers, and host bus adapters to ensure they are a simple plug-and-play storage solution.
