Data Center Hard Drives

Massive capacity for your data center.

Driving value on Big Data

When you store, integrate, and analyze complex data, you can uncover new trends, valuable patterns, and strategic opportunities. To extract these data-driven insights from Big Data workloads, you need advanced storage infrastructure with purpose-built capabilities. 

Building data center capacity 

Designed for public and private cloud environments, our data center HDDs help you store massive amounts of data reliably, cost effectively, and energy efficiently. It’s not just about storing more data — it’s about doing more for your business with your data.

Deploying industry-first innovation 

With industry-first advanced technologies across our portfolio — including OptiNAND, ArmorCache, EAMR (energy-assisted magnetic recording), and HelioSeal — high-capacity hard drives from Western Digital already power some of the world’s most demanding Big Data workloads. 

ArmorCache

The ArmorCache feature, enabled by OptiNAND, provides enterprise power loss protection and increased performance.

OptiNAND

The latest in HDD technology, OptiNAND adds a flash layer to offload expanded metadata, reducing DRAM need.

EAMR (Energy-Assisted Magnetic Recording)

A breakthrough in HDD recording technology, EAMR enables higher areal density through increased bits per inch (BPI) on HDD tracks.
