类似的局面并非首次上演。2018年比特币暴涨时，显卡工厂产能几乎全数被区块链矿场吞噬，最终造成零售缺货、价格飞涨。 今年则在AI算力战下重复发生。行业人士承认，如今各大代工厂即便满负荷运转，仍填不满数据中心和企业对DRAM、NAND 的胃口，比如十铨管理层就坦言，现在不只是台式机内存，连GDDR6、GDDR7、LPDDR5几乎都买不上，在东南亚的部分电 商平台，发货时间甚至被拉长至半年以上。 事实上，冷数据存储方式也在近期出现变化。由于硬盘制造商未扩产，越来越多的数据中心将冷数据转移至固态硬盘，这进一 步加剧了NAND闪存的紧俏状况。假如某地突然增加机械硬盘生产，或许对固态盘供应有正向影响，但目前看来距离这种转折 还很遥远。 也有极少数反向案例可供参考。去年日本市场的DDR4库存意外过剩，偶然导致本地用户短时间享受了平价内存。然而仅两个 月之后，全球行情一体化依旧将价格拉升到高位，证明区域性"小阳春"难以长久。从整体趋势看，只要AI赛道继续狂奔，大众 购买力就只能被动等待新一轮市场变革带来的再平衡。 未来几年，除非有技术突破降低DRAM/NAND生产难度，否则对于绝大多数玩家和消费级用户，攒机和升级的窗口期只 ...
