Customer-Focused, Empowering Innovations

Western Digital HDD innovations help turn data into actionable insights and life-changing outcomes.

Eleven Disk

Whether you’re trying to reduce your data center’s carbon footprint or storing intellectual property in the race to cure cancer, rely on the Eleven Disk HDD to achieve your goals by optimizing storage density and power efficiency.

UltraSMR

UltraSMR enables large-scale deployments, so that massive data centers can power global social media platforms, access vast amounts of legacy financial data, or process extensive and complex genomic data.

ePMR

ePMR builds on conventional technology so that companies can keep pace with rapidly expanding volumes of data at minimal risk. Confidently store and protect medical records, deliver personalized shopping experiences, or monitor crop yields with ePMR.

ArmorCache

When it comes to handling heavy data workloads (think cloud storage services, big data, and AI systems), ArmorCache can help boost productivity by protecting data from power loss and improving performance.

OptiNAND

To close the gap between data growth and storage capacity and performance, Western Digital pushed the innovation envelope to create OptiNAND, which integrates iNAND in HDDs for a revolutionary, flash-enhanced technology.

HelioSeal

HelioSeal is foundational technology that keeps capacity moving forward— turning possibilities into reality, such as storing and delivering customized movie recommendations to millions and capturing and using data to make cities more energy efficient.

Triple-Stage Actuator

From powering AI to battle climate change to processing ML data to build smart cars, Triple Stage Actuator is a mechanical innovation that integrates with other technologies to enable organizations to ramp up storage capacity and performance.
