Data Center SSDs

Fast Data for Fast Decision-Making

Accelerating Access to Critical Data

From Large Language Models to IoT networks, the data-driven economy demands faster, more reliable access to data. With solid state technology, Western Digital can help drive these complex, high-capacity workloads and applications.

Pushing Performance with NVMe™

Powered by NVMe, enterprise solid state drives (eSSDs) can help accelerate data center workloads, achieve maximum throughput, and transform your data into actionable insights for your whole team.

Unlock Data Intelligence with Key Tech 

Key advancements in NAND scaling,  QLC (quad-level cell) flash memory, and NVMe have enhanced performance across our portfolio. Learn more about what they can do for your business applications.


Leveraging decades of expertise in NAND flash memory, our innovations in both vertical and lateral scaling allow greater capacity in a smaller die with fewer layers.


Designed for high-performance, NVMe is a protocol that is well suited for highly demanding and compute intensive enterprise, cloud, and edge data ecosystems.


Quad-level cell (QLC) flash memory is a capacity-optimized NAND memory technology that delivers a per-terabyte cost that matches or beats hard-disk drives (HDDs).
