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.
