Western Digital benefits from HDDs' low storage cost and growing cloud demand, with higher NAND prices adding pricing power. Nearline bit demand normally grows 20-25% with some deflation, while AI data growth now exceeds 30%; HDD costs ~$0.02-$0.03/GB versus ~$0.25 for NAND. Before AI, the consolidated, ~95% cloud-exposed market looked worth a low-to-mid-teens multiple of normalized EPS. Entry barriers are extremely high, but irrational competition among the three players is a risk. x.com  x.com  … Show more

Western Digital's margins are riding price increases that management sees lasting three to four more quarters. Price per terabyte rose 28% year on year while cost per terabyte falls less than 10%; December gross margin is guided to 60-61%. At about 10x fiscal 2028 consensus earnings, the stock prices in an early end to hikes despite scarce heads and media that WD mostly makes itself. Buy, $406. Long-term contracts cover less volume further out, leaving spot sales exposed if pricing turns. x.com  … Show more

AI data and content creation could lift Seagate's and Western Digital's cross-cycle earnings even if supply catches up and pressures prices and margins. Western Digital reported hyperscaler demand signals through 2030/31, making 2013-2024 normalized earnings a poor baseline. Still not a huge fan of their stocks given their large premium to memory makers and Toshiba's production ramp. x.com  x.com 

AI and data centers now drive HDD demand, so Western Digital's long customer visibility suggests AI demand could last into 2030-31. CEO Irving Tan says the company has good visibility through 2030-31 across its seven top customers, with demand signals increasing over time. That adds to the case for durable demand, though the AI runway is an inference from the HDD outlook. x.com 

Alphabet's AI spending is visibly turning into revenue, more than many other names can say today. Cloud is nearly a quarter of revenue, growing 103% at a 36% operating margin with a $561B backlog; total revenue rose 25%, operating income 30%, and margins are expanding. Free cash flow has been negative for two quarters, capex keeps climbing into 2027, and AI leaves search monetization uncertain. x.com 

A supply response could compress Western Digital's pricing and margins, eroding its apparent cheapness. Its 2013-24 normalized earnings merit a look: even huge demand growth in other industries eventually drew supply and mediocre returns. A digestion/reset would hurt buy-and-hold investors, though the outcome is uncertain. Pre-AI economics were mediocre and unlikely to become amazing post-AI; TSMC's stronger pre-AI economics make its post-AI case better. x.com  x.com  x.com 

Hard drives from Western Digital and Seagate are shouldering the bulk of the AI revolution's storage, and physical AI taking off would add even more demand. x.com 

Western Digital is about to play catch-up with the memory space. It has lagged as Micron, Sandisk, Samsung and SK Hynix ride NAND, DRAM and HBM price spikes, because it rides capacity storage for AI data lakes, which is real demand but a different, slower-moving market. x.com 

The valuation gap favors SK hynix and Samsung over Corning, Seagate and Western Digital. Companies trading at 20x are still called cheap while the memory makers trade at 2x; Corning is not cheap on a $4 run rate even with growth, and neither are Seagate or Western Digital. The gap should narrow as memory rises while HDD stalls. x.com  x.com 

Western Digital is the cheap mass-storage backbone of AI infrastructure, riding the same tailwind as memory through hard drives rather than NAND, which was spun off as Sandisk. After a roughly 1,000% gain in a year, fresh block buyers just took 400 of the $900 calls into 2027, a sign big money thinks the move is not done. x.com
