Competitive Comparison

SanDisk vs. Micron vs. Western Digital

Two memory-cycle bets I hold, benchmarked against the storage-industry peer I don't — NAND flash, DRAM, and hard-disk exposure to the same AI-storage demand story.

Market cap, P/E, PEG, EV/EBITDA, and capex sourced via public filings and financial-data aggregators (GuruFocus, StockAnalysis, company earnings releases), as of August 2026. PEG ratio sourced primarily from GuruFocus where available; different providers use different growth-rate assumptions, so figures elsewhere for the same stock can vary by several multiples. Gold-highlighted column(s) indicate the name(s) actually held in this book.

Why SanDisk and Micron, not Western Digital

SanDisk (NAND flash) and Micron (DRAM, with some NAND) are my two direct memory bets, and I hold both deliberately because they're exposed to different sides of the same AI-storage demand story rather than being redundant. Western Digital, mechanically a storage-industry peer, is a genuinely different business — spinning hard-disk drives rather than solid-state memory chips — and its EV/EBITDA of 36.96x is actually richer than SanDisk's or Micron's despite HDDs being the more commoditized, lower-growth side of storage. I don't hold WDC because it doesn't give me the same direct high-bandwidth-memory-for-AI exposure that Micron does, and it duplicates rather than diversifies the SanDisk NAND thesis without adding a distinct angle.
