Capacity 16TB Per drive Transfer Rate 262MB/s Maximum sustained Cache 512MB High-performance buffer MTBF 2.5M hrs Projected reliability Warranty 5 Years Limited warranty Why Choose WD Gold for Enterprise Storage Built for Heavy Workloads WD Gold drives are rated for up to 550TB per year in workload throughput, making them ideal for servers, RAID arrays, and storage appliances that run continuously. CMR (conventional magnetic recording) technology ensures broad compatibility and predictable performance across all supported configurations. Vibration Protection (RVS) Western Digital's exclusive Rotational Vibration Safeguard (RVS) uses dual sensors to detect and counteract vibration in real time. As a result, the drive maintains stable performance even in multi-drive enclosures and high-density rack environments where vibration is unavoidable. HelioSeal Technology At 16TB, WD Gold uses HelioSeal helium-sealed technology to reduce internal turbulence and power consumption while enabling higher platter densities. The result is greater capacity, cooler operation, and extended drive longevity compared with air-filled alternatives.
