WD Prepares Voluminous Re+ HDDs for Data Centers

Western Digital announces a new high-capacity 3.5-inch HDD for data centers. The WD Re+ will be available in versions of up to 6 TB. All of them are designed with power-saving ideas in mind; hence, their maximal power consumption index does not go above 6 W. The new-comer employs five-platter architecture and SATA 6 Gb/sec interface that guarantees the maximal efficiency level. Moreover, its MTBF index approximates 1.2 million hours on average workload index of 550 TB per year.



The WD Re+ is distinguished by the following advantages:

— the incorporation of dual actuator positioning system that improves the drive’s working efficiency;

— the implementation of RAFF technology that monitors HDD parameters in real time and compensates for the linear and angular vibration;

— the employment of StableTrac technology that reduces vibrations and stabilizes drive platters;

— the usage of TLER technology that prevents latencies or an abrupt destruction of RAID … …
