WD 0B35950 Hard Disk Drive

Built for 24/7 enterprise storage, the Western Digital Ultrastar 4TB SATA hard drive (WD 0B35950) delivers the reliability and endurance IT teams need for servers, storage arrays, and surveillance deployments. This internal 4TB SATA/600 drive supports heavy workloads—rated up to 550TB per year—and includes a 128MB buffer to sustain consistent throughput across continuous read/write operations. HelioSeal technology reduces power consumption and enables higher capacity per chassis, lowering overall cost of ownership in dense data centers. Advanced features such as Rotational Vibration Safeguard (RVS), dynamic fly-height adjustment, and a dual-stage actuator preserve performance and minimize errors in high-vibration racks or multi-drive surveillance systems. Backed by enterprise-class testing and a 5-year limited warranty, the Ultrastar DC HC310 is optimized for servers, storage systems, security, and monitoring applications where uptime and data integrity are critical. Choose the WD 0B35950 to simplify integration and protect your data—ideal for data centers, NVRs, and large-scale video surveillance projects.
