Stifel维持Landstar股票"持有"评级，关注数据中心货运前景

2026年8月，三星在德国科隆游戏展展示P9和P7便携式固态硬盘，两款产品都采用USB4连接，面向大型游戏、高清视频和内容创作带来的存储需求。旗舰P9公布的最高顺序读取速度为每秒4000兆字节，顺序写入最高每秒3800兆字节，并提供最高8TB容量版本。

P9强调持续写入和专业拍摄流程，支持高分辨率素材的直接记录、存储与编辑；P7则侧重日常工作和移动使用，兼容电脑、手机、相机等多类设备，并通过两米跌落及相关耐久测试。系列规划容量从1TB到8TB，公告安排自9月起逐步在全球推出。USB4接口提高了便携存储的性能上限，但实际传输速度仍会受到主机接口、线材、文件类型和工作温度影响。对创作者而言，这类产品的价值不仅是缩短拷贝时间，也在于让高容量素材随身携带，减少在不同设备之间反复调整工作流程的负担，选用时需核对设备的接口能力。
