Data Center Hard Drives
Massive Data Storage Capacity
Driving Big Data Value
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.
HelioSeal
Hermetically sealed helium inside HDD drives enables more disks, as well as quieter operation and low power usage.
Finding the right storage for your data depends on your specific business needs. Reference the chart below to find a solution that balances capacity, cost, performance, and more. And if your needs are more complex, talk to one of our experts and we can help you build out the optimal data infrastructure for your organization.
