Unverified接口速度越高、散热要求越高，导致体积重量增加：Thunderbolt外置盘往往带大面积金属散热壳，重量是普通USB移动盘的2-3倍，纯便携需求不必上雷电75% similar Unverified速度与发热的权衡：Thunderbolt/USB4高速盘持续读写时金属外壳会明显发热（可达50-60℃），需带散热马甲或金属壳设计。追求极致轻薄的塑料壳盘往往做了降速保护，长时间高负载不如金属壳稳定74% similar Unverified接口速率与散热成本呈正相关：Thunderbolt硬盘盒发热大、需主动/被动强化散热且成本翻倍，日常备份和文档存储用USB3.2 Gen2（10Gbps）足够，无需上雷电74% similar Unverified速度越快、缓存越大、散热越好，体积重量与发热往往越大：Thunderbolt高速盘多带金属散热外壳偏重，纯便携轻薄盘则牺牲持续写入稳定性72% similar Unverified速度越快发热越明显：Thunderbolt和20Gbps盘长时间大文件传输会明显发烫甚至触发降速，选带金属外壳或散热片的型号能维持持续写入性能72% similar
