Why AI Ignites NAND Demand
Frontier model training cannot rely solely on GPU memory (HBM). Fast checkpointing dumps multi-hundred-gigabyte model weights every few hours to prevent catastrophic training loss during hardware faults, driving high-capacity PCIe Gen5 NVMe eSSD demand.
The QLC vs TLC Density Shift
Hyperscalers are migrating from rotating magnetic disks (HDDs) to ultra-high-density 61.44TB and 122TB QLC eSSDs. High read-bandwidth and reduced power consumption make high-density flash the premier tier for vector embedding search and RAG retrieval pipelines.
Operating Leverage in Memory Cycles
NAND fabricators experience intense earnings beta. With massive fixed fab depreciation, when bit demand outstrips supply, ASP jumps directly expand gross margins from single-digit cash burn into 40%+ operating profits, unlocking rapid market re-ratings.
