Product details

Overview

The MDD MAXDIGITALDATA HC520 12TB Enterprise HDD is a refurbished, DoD-wiped drive prepared for demanding data-center workloads. It has undergone full factory diagnostics to ensure reliability after years of service in datacenter servers, and it ships as a renewed unit with a 5-year warranty.

Key specifications and design

  • 12TB capacity for dense storage and long-term archiving.
  • 7200 RPM for responsive throughput and steady streaming of data.
  • Up to 256MB cache, depending on the model variant, to smooth bursts and improve access times.
  • SATA 6.0 Gb/s interface for straightforward integration with modern servers and NAS.
  • Helium-sealed, 7Stac design enabling higher storage density in a standard 3.5-inch form factor.
  • Optional Self-Encrypting Drive (SED) capabilities for HDD-level data protection.
  • MTBF rated at 2.5 million hours, reflecting long-term reliability expectations for continuous operation.

Why this drive could fit your setup

In high-density data centers, capacity and energy efficiency matter. The HC520’s helium technology reduces turbulence and power use, helping to maintain cooler operation while expanding storage without increasing rack space. It is built for 24/7 workloads and can slot into servers, NAS systems, RAID arrays, and backup targets.

Use cases and deployment ideas

  • Bulk storage and nearline archives in enterprise deployments.
  • Massive scale-out installations that require predictable capacity growth.
  • Backup and disaster recovery appliances where reliability matters.
  • CCTV and surveillance storage for long-term retention and continuous writes.
