About the WD Gold 4TB Enterprise SATA HDD
SATA 3.5-inch enterprise HDD with an exceptional 2,000,000-hour MTBF, the WD Gold 4TB (part number WD4002FYYZ) is Western Digital's proven workhorse for 24/7 datacenter deployments. Built on CMR technology with a 7200 RPM spindle, 256 MB cache, and native command queuing support, this drive delivers the reliability and performance standards that mission-critical storage infrastructure demands. The WD Gold series combines enterprise-grade vibration compensation through dual-stage actuator design with advanced error recovery control, ensuring consistent operation even in demanding multi-drive storage arrays and server environments.
Storage architects and IT procurement teams worldwide specify the Western Digital WD Gold for high-capacity RAID systems, NAS platforms, and surveillance infrastructure requiring predictable 550 TB/year workload capacity. The 4 TB model strikes the sweet spot between density and cost—ideal for organizations building out mid-range storage clusters without premium SAS overhead. Its 300,000 load/unload cycle rating and robust shock tolerance (30 Gs operating, 250 Gs non-operating) reflect real-world reliability demands. Low 6.4 W typical active power consumption also supports total-cost-of-ownership objectives in large-scale deployments where thermal and electrical budgets are tightly managed.
