Ultrastar DC HC530 14TB enterprise drive

The Western Digital Ultrastar DC HC530 is a 14TB helium-sealed hard drive built for enterprise storage arrays. It uses a SATA 6.0Gb/s interface, a 512MB cache and CMR recording technology in a standard 3.5-inch form factor. The HelioSeal design delivers up to 58% lower idle watts per terabyte compared with earlier air-filled models. A 2.5 million hour MTBF rating supports continuous operation in data centre environments.

Suited for high-capacity bulk storage.

This drive targets cloud and hyperscale storage, massive scale-out data centres, distributed file systems and object storage platforms such as Ceph or OpenStack Swift. It also fits surveillance analytics and big data workloads running on Apache Hadoop. The SATA interface and mechanical latency make it unsuitable for applications that demand the response times of solid-state media or workloads requiring a faster host bus than 6.0Gb/s.

SATA 6.0Gb/s interface governs host compatibility

The drive connects through a standard SATA 6.0Gb/s port and includes a SATA-to-SATA power adapter cable for legacy backplanes. A power-disable feature allows host-controlled power cycling. Systems without a free SATA data and power connection cannot use this drive without an additional controller.

Questions about this item

Will the 3.5-inch form factor fit my standard desktop drive bay?

Yes, the 3.5-inch form factor matches standard desktop and server bays, and the SATA 6.0Gb/s interface uses the same data and power connectors as other SATA drives.

What is the correct way to connect the included SATA-to-SATA power adapter cable?

Plug the adapter between the drive's SATA power connector and your PSU cable; the power-disable feature on pin 3 then lets the host control drive power without rewiring the backplane.

How long is the helium seal rated to last before the drive needs replacement?

The HelioSeal design is engineered for the drive's full service life, backed by a 2.5 million hour MTBF rating, so no periodic helium maintenance or resealing is required.
