Western Digital Launches 32TB UltraSMR and 26TB CMR HDDs

 More than just storage, Western Digital HDDs are key enablers for businesses looking to optimize their infrastructure, lower TCO and future-proof their data strategies. Constantly innovating to meet the needs of our data-driven world, Western Digital (NASDAQ: WDC) today announced that it is now shipping the world’s highest capacity UltraSMR HDD with up to 32TB 1 leveraging the time-tested, reliable energy-assisted PMR (ePMR) recording technology for hyperscalers, CSPs and enterprises. For those who want a drop-in ready HDD for today’s data-intensive workloads, the company is also now shipping the world’s highest-capacity ePMR CMR HDD with up to 26TB for enterprise and channel customers. With the world’s first commercially available 11-disk design and field-proven technology, these new drives reinforce Western Digital's commitment to delivering HDD technology that raises the bar on capacity, reliability and innovation.

The AI Data Cycle has emerged as a growth driver for the storage industry. As AI systems become more sophisticated, they process and generate vast amounts of data that must be stored efficiently. HDDs play a crucial role in this ecosystem, handling both the input side, where data is gathered, ingested and stored, and the output side, where AI content is generated and preserved. This dual role positions HDDs as a linchpin in the AI Data Cycle, ensuring that data is available when needed and stored with the lowest TCO.

Western Digital’s newest 26TB CMR and 32TB UltraSMR drives utilize multiple technological innovations to enable data centers to maximize their storage efficiency. In addition to ePMR, OptiNAND™, ArmorCache™ and a triple-stage actuator (TSA), the drives feature the world’s first commercially available 11-disk platform along with other design enhancements.
