Hard Disk Drive Demand Growth and the AI Data Center Buildout

HDD demand continues to climb as the ongoing AI-driven data center buildout adds to already-robust demand from traditional enterprise and cloud infrastructure. Beyond new capacity additions, a steady cycle of installed-base drive replacement and rising data center density goals are pushing shipments higher, as operators pack more capacity into the same physical footprint. Enterprises and cloud service providers continue to favor HDDs for several durable reasons. Cost per terabyte remains far lower than flash alternatives, making HDDs the economical choice for storing massive and growing data volumes. Performance, while not matching SSDs, is more than sufficient for the bulk of enterprise and cloud workloads, particularly mass-capacity and archival use cases. When factoring in acquisition cost, density, and operational efficiency, HDDs also deliver the lowest total cost of ownership at scale. Underpinning all of this is the relentless growth in data creation from AI training and inference to everyday enterprise operations which continues to expand the addressable base that HDDs are best positioned to serve.

HDD Technology for the AI Era: Scaling Capacity, Performance and the Storage Ecosystem

The rapid growth of AI and cloud infrastructure is creating new requirements for storage capacity, performance, power efficiency, cost, and scalability. HDD technology will continue to evolve to address these changing needs through innovations across recording technology, media, heads, mechanics, electronics, interfaces, firmware, and system architecture. This presentation will discuss the long-term direction of HDD technology and how continued advances in areal density, drive architecture, and data throughput can enable substantially higher capacity and performance. We will also explore the growing importance of the broader storage ecosystem, including host interfaces, software, and system integration, as HDD capabilities advance beyond traditional architectures. Together, these developments can help HDD remain a foundational technology for cost-effective data storage in the AI era and beyond.

Toward the Ultimate Potential of HDD-Based Data Storage

This presentation highlights a recent Heat Assisted Magnetic Recording (HAMR) spin-stand demonstration of 8.1 TB/disk enabled by aggressive heads and media, shingled and two-dimensional magnetic recording, and multiple readback processing. Also, we discuss progress in ferroelectric data storage research supported by fundamental materials modeling. We conclude with examples of how artificial intelligence is being applied to accelerate model development, enhance simulation efficiency, and identify novel materials opportunities, helping guide the next generation of high-capacity storage technologies.

MSTC活動ご紹介

生成AIやクラウドサービスの普及が急拡大する中、これらを支えるデータセンターの需要が急速に高まっています。HDDを含めたデータストレージは、増え続けるデータを記録・保存する中核的な役割を担っており、さらなる深化が求められています。MSTC (Mass Storage Technology Consortium)は、データストレージ業界とアカデミアとをつなぐ、ワールドワイドな産学連携コンソーシアムであり、今回、MSTC活動のご紹介をいたします。併せて、東芝のHDD技術に関する取り組みについてもご紹介いたします。
