文章摘要

人工智能热潮导致数据存储设备供不应求，企业级硬盘交付延迟长达两年。为应对短缺，云服务商转向QLC NAND固态硬盘，但抢购潮又造成QLC芯片短缺，预计到2027年QLC将超越TLC成为主流存储方案。

文章总结

人工智能通用技术（AGI）竞赛正引发数据中心建设狂潮，其速度已远超产业链供给能力。内存行业首当其冲——DRAM短缺导致价格数月内翻倍，如今存储设备也陷入危机。据Digitimes报道，企业级机械硬盘交付周期已延长至两年。

这种局面迫使超大规模数据中心转向QLC闪存固态硬盘，这种方案既能控制成本，又可满足冷存储的耐久性需求。但蜂拥而至的采购导致QLC闪存也出现短缺——北美和中国云服务商正展开抢购，部分NAND厂商的QLC产能已排期至2026年。行业预测到2027年初，QLC市场份额将超越主流TLC闪存。

供应链危机带来连锁反应：闪迪率先将NAND芯片提价50%（两个月前预警幅度仅为10%）。正如威刚董事长上月预警，存储行业缓冲产能已从2-3个月骤降至数周。虽然厂商财报因此亮眼，但最终代价将转嫁给普通消费者——电子产品短缺阴云再次笼罩市场。

评论总结

以下是评论内容的总结：

  1. 对HDD延迟和SSD价格上涨的调侃

    • "delivery times for enterprise-grade HDDs delayed by two years...I sleep...This could lead to SSD prices rising worldwide...Real shit" (mock-possum)
    • "So far, due to the AI boom, we're lacking: HDDs, SSDs, DRAM, GPUs, Power..." (criemen)

  2. 长期看好的观点

    • "This is a long term good thing...By 2028 or so we'll have a 50% drop in price-per-storage" (margalabargala)
    • "Micron has a new US fab coming online in 2027, which should improve supply" (walterbell)

  3. 对AI泡沫的担忧

    • "And when the AI bubble bursts, 'refurbished' HDDs and GPUs will flood the market" (karlkloss)
    • "I really hope the AI bubble bursts sooner rather than later...the crash will lead to even longer-term supply distortion" (mrandish)

  4. 对QLC NAND技术的质疑

    • "How does that work, doesn't QLC have less write endurance?" (krackers)

  5. 供应链操纵的历史对比

    • "DRAM price fixing scandal: 1998-2002, 2016-2018" (walterbell)
    • "During 1998-2000, AOL was ordering so many free trial CDs that it locked up world production" (mchannon)

  6. 供应链污染警告

    • "the pollution of the supply chain with refurbished/recertified stock being sold as 'new'" (rsync)
    • "carefully vet your incoming stock with SMART tools" (rsync)

  7. 对AI发展的负面看法

    • "The future of AI is everything we liked getting ruined by AI" (evanjrowley)
    • "Worse than nukes race, which at least did not affect common man" (zkmon)

  8. 存储危机的个人体验

    • "Thank god I built my NAS in early October" (ls612)
    • "It's rough out there and has become increasingly difficult to maintain our pace of storage deployment" (rsync)

  9. 创新可能性的预测

    • "Soon we'll see many 'AI' product that analyses network storage to identify files that could be deleted" (whynotmaybe)

  10. 政府干预的建议

    • "Sometimes, I think government supply control isn't that much of a bad thing" (mschuster91)
    • 提到Chia加密货币导致2021年存储价格暴涨的历史 (mschuster91)
