Western Digital CEO says AI storage demand is strong, order visibility with top seven customers extends to 2030
English text is being prepared.
At the earnings call, Western Digital's CEO said AI is essentially a data system, and the massive generation of data brings HDDs a more enduring market opportunity than computing power; order visibility with the top seven core customers already extends to 2030-2031. The company's HDD capacity for 2026 is fully sold out, long-term supply agreements run through 2028, and fiscal Q1 2027 revenue grew 55% year over year, but revenue and shipments remain constrained by supply capacity. The article also notes that a single AI server has a storage configuration of 1.7TB, more than three times the 0.5TB of a traditional server.

别只盯着GPU了！西部数据揭AI真相：存储才是硬瓶颈 订单排到2030年快科技下载客户端 独家抢先看2026年10月23日 14:30:02 来自河南Updated 2026年10月23日 14:47:02
快科技10月23日消息，据Digitimes报道，西部数据CEO在近期财报电话会上直言，AI本质上是数据系统，任何工作负载都会生成海量数据，这为HDD带来了比算力更具持久性的市场机遇。其前七大核心客户订单可见度已排至2030至2031年。
这一判断直接反映在产能上。西部数据2026年HDD产能已全部售罄，长期供应协议甚至签到了2028年。公司2027财年第一季度营收同比大增55%，下季度指引远超预期，但管理层坦言，收入与出货量仍受限于供给能力，而非需求不足。
AI对存储的拉动，远不止GPU需要HBM和高速SSD这么简单。GPU负责训练和推理，企业级SSD承接热数据，而HDD则保存训练数据集、历史版本、日志、视频及备份。
随着AI从训练转向推理，KV缓存管理等任务正从昂贵的GPU显存转移到共享高性能存储，进一步推高了容量需求。
具体到单机配置，差距极为悬殊。单台AI服务器的存储配置高达1.7TB，而传统服务器仅有0.5TB，前者是后者的三倍以上。
当云厂商和超大规模企业扩建AI集群时，采购清单绝不会只有GPU服务器，海量数据的落地、归档与长期保存，才是存储需求真正的放大器。
