NAND Flash
Non-volatile storage feeding AI training datasets
NAND flash is non-volatile storage (SSDs) that, while not part of the HBM stack, is critical to AI infrastructure for storing massive training datasets and checkpoints and for high-capacity enterprise SSDs in AI data centers. Makers include Samsung, SK Hynix (which owns Solidigm), Micron, plus Kioxia and Western Digital. High-layer-count 3D NAND (200+ layers) and fast enterprise SSDs are increasingly demand-pulled by AI storage tiers.
