Seagate's gross margin jump to 57.8% from 52.7% shows pricing power in a supply-constrained hard-drive market. AI data needs storage, hyperscalers seek capacity, and HAMR packs more terabytes into existing factories; roughly 90% of big-cloud data sits on hard drives. Sales reached $4.2B and next-quarter guidance of $4.8B beats the Street's $4.53B. This cycle looks to be accelerating rather than peaking. Overweight, $1,050 target. x.com  x.com 

SanDisk's data-center flash growth shows AI inference is becoming a larger storage customer. Data-center revenue reached $4.8bn, up 61% in a quarter and over 40% of sales; total revenue of $11bn and EPS of $49.51 beat expectations. Guidance of $12.4bn revenue and $56 EPS suggests feared supply normalization has not yet eroded pricing. Overweight, with a $2,700 target. x.com  x.com 

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 

Sandisk's fast-growing data-center revenue strengthens its case among memory names with upside. Data-center revenue rose 61% quarter over quarter; revenue of $11.03B, adjusted EPS of $49.51 and adjusted gross margin of 85.1% all exceeded estimates. For upside among Micron, Sandisk and Kioxia, Micron ranks first, then Sandisk, then Kioxia, until further guidance. x.com  x.com 

Western Digital's hard drives capture AI-generated data, supporting stronger margins and guidance. Most data from models, agents and robots ends up on hard drives. Revenue rose 55% to $4.38B, gross margin hit 58.1%, and next-quarter revenue guidance rose to $5.0-5.2B versus $4.57B expected; EPS guidance midpoint is 21% above consensus. Before earnings, at ~15x earnings it looked priced as a cyclical, not an AI winner. Overweight, $613 target and 62% indicated upside in the pre-earnings report. … Show more

Sandisk's datacenter shipments and restrained bit-supply plan strengthen its growth case, without settling contract protection in a downturn. Management attributed roughly 60% of fiscal Q1 revenue growth to volume and 40% to price; datacenter sales rose 61% sequentially to $4.8B, supplying 88% of total growth. It retains mid-to-high-teens bit growth rather than accelerating supply. Consumer sales fell 29%, and the CFO cautioned against carrying Q2's growth rate into fiscal Q3. 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 

Rising memory contract prices strengthen the case for memory stocks still far below their highs. JPMorgan forecasts Q4 DRAM prices up 13% and NAND up 18%; Micron is 28% below its 52-week high, Seagate 44%, Sandisk 47% and Western Digital 55%. x.com 

Networking, power and compute look more durable than cyclical memory in the AI buildout. Lumentum's revenue compounded year after year across the 2010s and 2020s, unlike Micron's; AWS revenue also compounded. Lumentum, Nebius, Bloom Energy and Credo should heavily outperform SanDisk and Micron from here, though AI itself remains heavily doubted. x.com  x.com 

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
