便携 SSD 悬浮主视觉，橙色挂环点睛

One unbranded portable SSD floating slightly above a matte stone plinth, brushed graphite aluminum body with a small orange silicone loop and a visible USB-C port, three-quarter studio 3D advertising view. Long narrow highlights follow the grain, faint grounded shadow, pale warm background, minimal composition, no text, logos or speed claims. Original generic design, no real brand or fabricated specifications.

一块无品牌便携SSD略悬于哑石台上，拉丝石墨铝机身、小橙硅胶挂环与可见USB-C口，三分之四棚拍3D广告视角。细长高光顺着拉丝，淡落影、浅暖背景、极简构图，无字品牌和速度宣称。 原创通用设计，不虚构真实品牌参数。
