Western Digital Ultrastar DC HC690 32TB 3.5" SATA 7200RPM Data Centre Hard Drive

Record-Breaking 32TB Capacity with 11-Disk SMR Design
Built on the world’s first 11-disk Shingled Magnetic Recording (SMR) platform, the HC690 delivers up to 32TB of storage in a standard 3.5" form factor—ideal for hyperscale data centers aiming to maximize storage density without increasing physical space.

OptiNAND and UltraSMR for Optimized Performance
Integrates Western Digital’s OptiNAND technology and UltraSMR to enhance tracks-per-inch (TPI), enabling higher capacity and improved performance, especially in sequential write-heavy workloads.

HelioSeal Technology for Energy Efficiency and Longevity
The helium-filled design reduces internal turbulence and power consumption, resulting in one of the lowest power profiles in its class while maintaining high reliability and thermal efficiency.

Enterprise-Grade Reliability and Vibration Protection
Rated for 550TB/year workloads and up to 2.5 million hours MTBF, the HC690 includes Rotational Vibration Safeguard (RVS) and Dynamic Fly Height technology to ensure consistent performance in high-vibration environments.

Flexible Write Cache with ArmorCache
Offers both Write Cache Disabled (WCD) for enhanced random write performance and Write Cache Enabled (WCE) for data protection during power loss, giving data centers the flexibility to tailor performance to specific workloads.
