description: "In many people's minds, $Seagate Tech(STX.US) is just that clunky, spinning mechanical hard drive inside a desktop PC—not sexy, not AI, no compelling narrative. Yet, over the past year, it has quietly climbed from its 52-week low of $63 to a historic high of $460, a gain of over 567%, outperforming many AI concept stocks... What's the logic? The explosive construction of AI data centers requires storage for video data and AI training data. For storing massive amounts of cold data at the terabyte level, the cost efficiency of mechanical hard drives is something SSDs simply cannot match. No one buying PCs anymore? No problem, hyperscale cloud vendors are placing orders like crazy.Earnings consistently beat the shorts: The latest Q2 earnings reported EPS of $3.11, beating Wall Street's expectation of $2.74 by 13.5%. This marks multiple consecutive quarters of beats. Gross margin reached a record high of 40.1%, quarterly free cash flow was $427 million, and the quarterly dividend was raised by 3% to $0.74 per share. The strongest moat: The new-generation HAMR technology platform, Mozaic, is already in mass production, supporting capacities up to 44TB. It has been fully certified by all of the world's top five cloud vendors. Production capacity for 2026 is fully booked; supply simply can't keep up with demand.The only risk is the potential expansion of AI chip export controls. If this leads to a contraction in cloud vendors' business in China, storage demand could be pressured. Also, with a 567% gain over 52 weeks, it's worth considering how much of the good news is already priced in."

- **复利进行时 · 2026-03-18T12:14:30.000Z**: The 44TB single drive is indeed an industry barrier. Western Digital has been chasing this technology for several years and still hasn't achieved mass production. Seagate leads by at least 12-18 months.

- **抄底练习生 · 2026-03-18T12:14:14.000Z**: Aren't HDDs a sunset industry? SSD prices keep dropping, and they'll eventually replace all HDDs. Are you still buying at a high price now?
- **接二连三 · 2026-03-18T12:13:58.000Z**: Back then, my colleagues asked me what to buy, I said Seagate, they laughed at me for buying hard drives. Now I'm laughing while counting money 😂 Mechanical hard drives have been severely undervalued for too long.
