Better Buy: Sandisk or Nvidia Stock? - The Globe and Mail

This article provides an in-depth comparison between two semiconductor companies, NVIDIA and SanDisk, analyzing their investment potential in the context of the AI boom. NVIDIA's GPU business has beco... Read original →

NVIDIA’s GPU dominance in AI training is triggering a full-stack rearchitecture—from HBM memory interfaces and NVLink protocols to liquid cooling—creating a defensible ecosystem moat. In contrast, SanDisk’s NAND flash, though boosted by SSD demand in AI data centers, remains vulnerable to commoditization and supply shocks from Samsung or Kioxia. U.S. export controls on advanced compute chips inadvertently reinforce NVIDIA’s compliance-led design advantage, while NAND’s geographic concentration in Taiwan, China, and South Korea heightens supply chain fragility. Over the next 12–24 months, as AI inference migrates to edge devices, GPU programmability will outpace NAND’s diminishing returns from QLC scaling and soaring 3D stacking costs. Verdict: SanDisk is a cyclical bet; NVIDIA is the structural winner.
