WD Ultrastar DC HC580 22TB SATA 3.5" Internal HDD — Base (SE) OptiNAND, 7200 RPM, 512MB Cache (0F62785)

Designed for data-center environments, the WD Ultrastar DC HC580 22TB Base (SE) 3.5" SATA internal hard drive pairs OptiNAND with a 512MB cache and a 7200 RPM spindle for high-capacity storage. OptiNAND integrates persistent flash memory with the magnetic media to reduce storage footprint and improve metadata efficiency. High-density recording is achieved through energy-assisted magnetic recording (EAMR) combined with a triple-stage actuator (TSA) and HelioSeal helium technology, delivering large capacity while minimizing power draw. ArmorCache enhances overall performance and provides enterprise-grade protection for in-flight data by guarding against data loss during unexpected power interruptions.
