About the WD Ultrastar DC HC700 Enterprise HDD (Expected) - 28TB
The WD Ultrastar DC HC700 28TB enterprise HDD operates at 7,200 RPM, positioning it as a high-capacity solution for mission-critical data centers requiring dense storage with sustained performance. Part number WUH722028BALE6L4 delivers 28TB of raw capacity in a standard 3.5-inch form factor, engineered for large-scale deployments where cost-per-terabyte and reliability are equally important.
Built on Western Digital's proven Ultrastar DC HC700 platform, this drive incorporates ePMR recording technology with OptiNAND and HelioSeal helium-filled design to maximize areal density while minimizing power consumption. The 512MB cache and dual-stage actuator with rotational vibration sensors ensure consistent performance in multi-drive RAID arrays and high-bay storage environments. With an annualized workload rating of 550TB/year and 600,000 load/unload cycles, it meets the demands of 24/7 data center operations. Storage architects and IT infrastructure teams specify this drive for large-capacity nearline and archive applications where energy efficiency matters. The SATA 6Gb/s interface integrates seamlessly with legacy and modern storage controllers, while typical active power consumption of 9.0W and idle power of 5.0W support green data center initiatives. Operating temperature range of 0°C to 60°C accommodates standard and enhanced cooling strategies.
