WD RE hard drives are engineered to offer data hungry SAS storage systems the massive capacity they need without compromising top of the line performance. Advanced reliability and data integrity features allow for 24x7 operation in tightly packed vibration prone multi drive systems. This uncompromising combination of high capacity, peak performance and best in class reliability make WD RE drives ideal for business critical applications. Industry’s highest capacity nearline drive - WD RE SAS hard drives are available in capacities ranging from 1 TB to 4 TB to suit even the most demanding storage needs. Highest performance for business critical applications - WD RE delivers 6 Gb/s transfer rates, sustained sequential data rates of up to 182 MB/s and high random I/O rates. Designed for quality and reliability - With a field tested 1.4 million hour MTBF, this high performance drive delivers the highest level of reliability for 24x7 operation in up to 100 percent duty cycle applications. Dual port, full duplex connectivity - Offers higher reliability, performance and data availability by eliminating single points of failure, designed for leading business critical Enterprise topologies. Environmentally conscious - In addition to being RoHS compliant, WD RE is built with halogen reduced components. NoTouch 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. Dual stage actuator technology - A head positioning system with two actuators that improves positional accuracy over the data track(s). 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. Vibration Protection - Enhanced RAFF technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration in real time. The result is a significant performance improvement in high vibration environments over the previous generation of drives. Multi axis shock sensor - Automatically detects the subtlest shock events and compensates to protect the data. Dynamic fly height technology - Each read write head’s fly height is adjusted in real time for optimum reliability. Ultra compatible - An ultra fast 6 Gb/s SAS interface enables easy integration into SAS storage subsystems while delivering twice the interface speed of traditional 3 Gb/s SAS nearline hard drives.
