Enterprise Capacity Drive

The Western Digital Ultrastar DC HC560 is a 20TB 3.5-inch internal hard drive built for enterprise storage systems. It operates at 15000 RPM over a SATA 6.0Gb/s interface and uses ePMR with CMR recording technology. The drive integrates OptiNAND flash and a 7th generation HelioSeal platform to support high areal density.

Suited For Bulk Workloads

This drive suits hyperscale clouds, service providers and smart video surveillance platforms that need cost-effective capacity at scale. It is not for systems that require a 2.5-inch form factor or an interface other than SATA 6.0Gb/s. Buyers needing lower power consumption per terabyte should evaluate alternative enterprise models.

15000 RPM Spindle Speed

The 15000 RPM spindle speed is the key specification that determines whether this drive meets the performance profile for active enterprise datasets. It delivers higher sustained throughput than standard 7.2K enterprise drives while maintaining the 20TB capacity in a standard 3.5-inch bay. Verify that the host enclosure and controller support this rotational speed class.

Questions about this item

How can I confirm the drive is running at 15000 RPM after installation?

Use a SMART monitoring tool such as CrystalDiskInfo or the WD Dashboard to verify the rotational speed reads 15000 RPM and the SATA link negotiates at 6.0 Gb/s.

What ships with the drive and what must I source separately?

The 3.5-inch 20TB HC560 drive arrives in retail or OEM packaging; you must supply your own SATA data cable, SATA power cable and 3.5-inch mounting screws or tray.

Which Ultrastar model should I choose for a 20TB enterprise workload?

Select the WUH722020BLE6L4 (part number 0F38785) — the only HC560 variant listed at 20TB with a 15000 RPM spindle and SATA 6.0 Gb/s interface.
