The Western Digital revolutionizes the enterprise storage with the high-capacity, high-performance WD RE4 hard drives with 24x7 reliability for business-critical applications. These drives combine 64 MB cache with dual processors and dual stage actuation for lightning-fast performance in demanding server and storage applications. Technologically advanced acoustics minimize noise. Cool drive operation and enhanced reliability features help protect the drive and the data stored on it. Pick the drive that suits your needs with the confidence in knowing that all WD RE4 drives are built to the highest standards of quality and reliability.
High Performance With a combination of 64 MB cache, dual processors and SATA 3Gbps the WD RE4 internal hard drives deliver lightning-fast performance in demanding server and storage applications.
24x7 Reliability The WD RE4 hard drives are put through extended burn-in testing with thermal cycling to ensure reliable operation for always-on server or enterprise storage environment.
Dual Actuator Technology A head positioning system with two actuators 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.
RAFF Technology The enhanced RAFF technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration in real time for a significant performance improvement in high vibration environments over the previous generation of drives.
RAID-Specific, Time-Limited Error Recovery (TLER) Boasting Time-Limited Error Recovery (TLER) technology, the WD RE4 hard drives can effectively prevent drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.
Multi-Axis Shock Sensor Powered by the multi-axis shock sensor, the WD RE4 hard drives automatically detect the subtlest shock events and compensates to protect the data.
