## Long description

WD RE Enterprise SATA hard drives are designed for enterprise servers, storage systems and video surveillance where sustained write performance and reliability are required. These 7200 RPM drives are available in capacities up to 4 TB and include a 64 MB cache and a five-year limited warranty. The drives incorporate a dual-actuator head positioning system: a primary electromagnetic actuator for coarse displacement and a secondary piezoelectric actuator for fine tuning, improving head positional accuracy over data tracks and enhancing performance in vibration-prone multi-drive environments.
Advantages
WD RE drives provide higher reliability and sustained write performance suitable for write-intensive workloads. The 4th generation vibration tolerance and dual-actuator head positioning reduce read/write errors caused by vibration and improve track alignment. A 64 MB cache helps maintain throughput, while the five-year limited warranty offers extended manufacturer support for enterprise deployments.
