• Data storage at scale is tiered 

    Tiered storage—spanning HDD, flash, and tape—is the operational standard for hyperscale data centers and scalable AI infrastructure. 

  • The Drive Behind AI

    When data scales fast, weak architecture breaks faster.

  • Why HDD is essential to the AI economy

    Hard disks form AI’s foundational layer, providing durable, cost-efficient storage that enables AI systems to scale economically.

  • Reinventing storage for AI at scale

    CPO Ahmed Shihab on how training, inference, and the data inference produces have reshaped cloud storage, and why both flash and HDDs are winning.

    The case for storage tiering

    Different workloads, different storage.

    AI is really a data system

    Compute isn’t AI’s biggest challenge.

    AI’s essential layer

    AI infrastructure is more than compute.

    HDD and flash are both winning

    Compute digests demand. Data compounds.
