Product details

Overview

Meet the HGST Ultrastar DC HC520 12TB Enterprise hard drive. This edition delivers massive capacity in a standard 3.5-inch form factor, designed for dense, capacity-focused data centers and enterprise workloads. Renewed with zero hours of usage and backed by a one-year warranty, it offers reassurance alongside performance.

Key specifications include a SATA 6Gb/s interface and 7200 RPM operation, together with a large 256MB cache to help sustain throughput during bursty or parallel workloads. Helioseal helium sealing helps reduce drive-to-drive frictions, contributing to higher data density and quieter operation in busy racks. The PMR technology ensures reliable stackability in traditional enterprise deployments, while the power-disable variant provides a potential efficiency feature for destination ecosystems that support selective power control.

  • MTBF rated around 2.5 million hours for enterprise confidence
  • Manufacture recertified with zero hours usage and a 1-year warranty

Ideal use cases

  • Cloud and hyperscale storage environments requiring dense capacity
  • Bulk object storage deployments using Ceph, Hadoop, or similar platforms
