Highest capacity ePMR HDDs

December 2024 Infrastructure, Products & Solutions




Western Digital has announced that it is now shipping the world’s highest capacity UltraSMR HDD with up to 32TB 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, Western Digital is also now shipping the world’s highest-capacity ePMR CMR HDD with up to 26TB for enterprise and channel customers.

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 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 utilise multiple technological innovations to enable data centres to maximise 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.

32TB Ultrastar DC HC690 SMR HDD supports customer goals for cost-effective deep content storage at scale. These new HDDs have up to 257 MiB/s sequential performance and use as little as 5.5 W power idle, making them ideal for warm and cold data tiers.

26TB Ultrastar DC HC590 CMR HDD is a drop-in replacement for continued capacity growth with a reliable, field-proven technology foundation. This latest generation of drives delivers CMR capacity, seamless qualification, easy integration and rapid adoption, while maintaining superior dependability and reliability. The Ultrastar DC HC590 26TB CMR HDD features a sustained transfer rate of up to 288 MiB/s and utilises as little as 5.6 W power while idle.

Ultrastar Data60, Data102 Hybrid Storage Platforms are being qualified and integrated into the company’s Ultrastar Data60 and Data102 JBOD hybrid storage platforms, which are high-density, scalable storage solutions that are ideal for modern data centres, private clouds, and big data analytics. These platforms provide flexible configurations, accommodating up to 60 or 102 HDDs, and can deliver up to 3.26 PB of raw capacity. Key technologies like IsoVibe and ArcticFlow ensures reduced vibration and optimised cooling, resulting in better performance and reliability. Availability will begin by year-end.

26TB WD Gold SATA HDDs are designed for system integrators and resellers. Leveraging innovations from the Ultrastar HDD technology platform, the WD Gold 26TB HDD provides a no-compromise storage solution incorporating the company’s latest innovations to handle heavy, continuous read-write workloads in the toughest enterprise and commercial system environments. With a five-year limited warranty supporting up to 2.5 M hours MTBF (projected), WD Gold drives offer storage performance, reliability, durability and flexible capacity for small and medium businesses and design professionals whose mission-critical data and creative output are essential to their success.
