存储需求结构性短缺，推理瓶颈在存储，中国产能无外溢。
群联电子(Phison) CEO关于存储与投资框架的访谈摘要： “收过路费者”（Toll Collectors）： - 美光(Micron) ($MU) - SK海力士(000660.KS) - 三星电子 - 西部数据(Western Digital) ($WDC) - $SNDK T2层级： - $MRVL - $SIMO - 群联电子(Phison Electronics) 随着AI向边缘端迁移，设计连接存储与计算逻辑/软件控制器的公司将捕获巨大价值。 T3层级： - 纯存储(Pure Storage) ($PSTG) - NetApp ($NTAP) - 希捷(Seagate) ($STX) 随着Vera Rubin推理服务器推出，键值缓存(KV Cache)和数据生成的爆发将触发针对数据中心存储密度和高容量企业级固态硬盘(Enterprise SSDs)的硬件升级周期。 有趣的是：$EBAY（翻新电子产品）可能成为受益者。 - 做空/规避低毛利消费硬件。 - 做空/规避未对冲的汽车/IoT制造商。 主要Alpha观点： - “三年预付”现金流：存储晶圆厂要求3年现金预付款以保障供应。 - 推理瓶颈在于存储而非GPU：单批次1000万台$NVDA Vera Rubin平台需每台20+TB SSD，仅此项就将消耗去年全球NAND产能的20%。 - “中国供应过剩”看空论调已死： Pan完全驳斥了关于长江存储(YMTC)和长鑫存储(CXMT)的观点。中国内部AI需求巨大，将瞬间消化100%国内产量。不会有廉价中国存储流入全球市场来拯救西方硬件OEM。 访谈TLDR： 存储需求是结构性的。供应端无结束迹象。$INTC CEO上月已确认此点。
英文原文
TLDR of Phison CEO interview on Memory and Investment Framework: "Toll Collectors": - Micron ( $MU ) - SK Hynix (000660.KS) - Samsung Electronics, - Western Digital ( $WDC ) - $SNDK. T2: - $MRVL - $SIMO - Phison Electronics Companies that design the logic/software controllers connecting memory to compute will capture massive value as AI moves to the edge. T3: - Pure Storage ( $PSTG ) - NetApp ( $NTAP ) - Seagate ( $STX) As Vera Rubin inference servers roll out, the explosion in KV Cache and data generation will trigger a massive hardware upgrade cycle specifically focused on data center storage density and high-capacity Enterprise SSDs. Hilariously: $EBAY (refurbished electronics), might be a beneficiary. - Short / Avoid Low-Margin Consumer Hardware. - Short / Avoid Unhedged Auto/IoT Makers Main alpha points: - The "3-Year Prepayment" Cash Flow. Memory foundries are demanding 3 years of cash prepayments to guarantee supply. - The Inference Bottleneck is Storage, Not GPUs. A single 10-million-unit run of $NVDA Vera Rubin platform requires 20+TB of SSD per unit, which alone would consume 20% of last year's global NAND capacity. - The "Chinese Supply Glut" Bear Thesis is Dead: Pan entirely dismisses this point around YMTC and CXMT. China’s internal AI demand is so massive that it will instantly swallow 100% of its domestic production. No cheap Chinese memory will leak into the global market to rescue western hardware OEMs. TLDR from the interview: Memory demand is structural. No supply end in sight. $INTC CEO confirmed this last month.

研究PSTG后不看好其QLC闪存业务，明天将发帖。
@Ren_aramb 我今天早些时候其实正在深入研究 $PSTG。用于存储的 QLC 闪存(QLC Flash) 非常有趣，但（我）不看好。我明天还是会发帖，只是好奇大家有什么想法。

@Ren_aramb I was actually doing more research into $PSTG earlier today. QLC Flash for storage is very interesting, but nope. I'll post tomorrow anyway, was just curious what ideas people had.
