SanDisk Edges Out Micron as Better Buy Amid AI Boom with 97% Revenue Growth

The AI-driven surge in data center demand has lifted both Micron and SanDisk substantially above broader S&P 500 year-to-date performance, but SanDisk's growth metrics have been markedly stronger . The company posted 97% sequential revenue growth and 251% year-over-year sales growth, driven by its strategic pivot toward high-capacity NAND flash storage for data center and edge computing applications — segments where AI inference workloads are generating exceptional demand.

MU offers a lower valuation multiple and broader product diversification, with exposure to both DRAM and NAND markets. SanDisk operates as a pure-play NAND story, which amplifies both upside and downside depending on how that specific market cycle evolves. SanDisk's exceptional growth rates carry a premium valuation — the market is pricing in continued data center expansion and sustained AI storage demand rather than the mean-reverting cycle historically associated with semiconductor memory markets .

Analysts comparing the two companies have noted that SanDisk's focused positioning gives it a cleaner exposure narrative for the AI infrastructure buildout, while Micron's diversification across memory types may provide more resilience if NAND pricing softens. The 97% sequential revenue figure represents one of the strongest growth rates in the semiconductor sector this cycle, reflecting how rapidly data center operators are scaling flash storage capacity as AI model inference workloads multiply across enterprise deployments.
