Micron vs. Sandisk: Which Is the Better AI Memory Stock to Own for the Next 3 Years

While Sandisk has outperformed Micron in 2026 with 480% gains versus Micron's 220%, Micron is positioned as the better long-term investment for the next three years. Micron's dual exposure to both DRAM and NAND flash markets, combined with strong HBM demand, higher market share gains, and faster projected earnings growth, gives it an advantage over pure-play NAND flash manufacturer Sandisk. Both companies benefit from persistent memory chip shortages expected through 2029, but Micron's diversified product portfolio and stronger fundamentals make it the preferred choice.
