  • SATA interface for broad system compatibility
  • Ultrastar DC HC555 series engineered for datacentre workloads
  • First listed by manufacturer November 2025

Capacity and interface

The Western Digital Ultrastar DC HC555 provides 12TB of storage on a SATA interface. It is built for desktop systems that need high-capacity bulk storage in a standard 3.5-inch form factor. The drive spins at 7200 RPM for consistent throughput on large sequential workloads. It suits archivists, media libraries and backup arrays that prioritise capacity over latency.

Build integration

The drive connects through a standard SATA data cable and a SATA power connector from the host power supply. No additional controllers, brackets or adapters are required beyond what a typical desktop chassis already provides. It frees up M.2 slots for boot drives or caching devices while delivering multi-terabyte capacity on a single bay. Systems with limited SATA ports may need a port multiplier or HBA to add more units.

Thermals noise and power

At 7200 RPM the drive generates measurable vibration and audible seek noise during heavy access patterns. Adequate case airflow across the drive bay keeps operating temperatures within specification for continuous operation. Power draw scales with spindle activity and is supplied entirely through the SATA power connector. Quiet-focused builds may notice the mechanical noise compared with solid-state alternatives.

商品問答

What sustained workload limit appears first on the 12TB Ultrastar DC HC555?

The 7200 RPM spindle speed sets the mechanical throughput ceiling that shows up first under continuous use.

How much noise, heat or power does the WUH722012CLE6L4 produce when running all day?

The drive spins at 7200 RPM over a SATA interface, which determines its acoustic and thermal profile during extended operation.

What host connection must already be present for this 12TB SATA drive to work?

A free SATA data port and matching power connector on the motherboard or controller are required for the drive to operate.
