Seagate Technology was the second-biggest mover, rising more than 15% to hit its own new high alongside Silicon Motion. Western Digital followed with a nearly 10% gain, while SanDisk added nearly 7% and Micron Technology rose approximately 4%. The broad-based nature of the rally suggests the Silicon Motion beat was interpreted by markets as a positive read-across for the entire storage sector rather than a company-specific event -- a signal that demand for data storage infrastructure remains robust despite the uncertain macro environment. For crypto markets, the storage stock surge carries indirect relevance. Strong performance in semiconductor and storage infrastructure plays reflects sustained demand for AI compute and data center buildout -- a backdrop that has historically supported risk appetite across tech-adjacent assets including Bitcoin and AI-related crypto tokens.
