The Western Digital 8TB HDD BD Ultrastar 7200 rpm SATA 3.5″ Internal Data Center HDD from WD is an enterprise-grade drive designed for demanding 24×7 data storage solutions. Ultrastar drives are built to be durable, featuring up to an error tolerance of <1 in 1015, a MTBF rating of 2 million hours, and an Annualized Failure Rate (AFR) of 0.44%, depending on the model. Endurance aside, this drive offer fast 7200 rpm performance with 256 MB of cache and data transfer speeds of up to 249 MB/s.
Enterprise-Class Storage: 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.
Vibration Protection: 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 & Dual-Stage Actuator Technology: 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.
Compatibility Testing: 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.
