<p class="wp-block-paragraph">你花大价钱买了块 NVMe 固态，随手塞进一个便宜塑料盒当移动硬盘，刚插上飞快，拷到一半就开始掉速。ZDNet 撰稿人 Jack Wallen 常年用外接盘渲染 4K 视频，他把矛头指向了盒子本身——散热。</p>

<p class="wp-block-paragraph"><strong>他做了个对照测试。</strong> 同一块盘、同一根线、同一段中间带多层特效的视频，先放进普通塑料外壳渲染：进度 21% 时，预计剩余时间显示 1 分 23 秒。把盘换进铁威马 D1 SSD Pro（双鳍片铝合金外壳）再来一遍，同样是 21%，剩余只剩 56 秒。他又把两个壳子对调重测，结果一致。</p>



<p class="wp-block-paragraph">Wallen 说自己见过渲染时间因为过热被拉长近 25%。文件越大、渲染越久，盘就越热，掉速越明显。闪迪也明确提示过，传输过程中的高温会影响性能，而长期高温还会缩短固态盘寿命。</p>



<p class="wp-block-paragraph"><strong>有个不用工具的土办法：</strong> 拷大文件时用手摸一摸盒子外壳。烫手说明热量正在被导出去；一点都不热，反而意味着热全闷在盘上了。</p>



<p class="wp-block-paragraph"><strong>选购上，</strong> 优先金属外壳带散热鳍片的款式；带风扇的散热也管用，但体积大、噪音藏不住。文中这款 D1 SSD Pro 支持 8TB 的 M.2 NVMe 2280 固态，接口 80Gbps，装盘只需拧一颗十字螺丝，缺点是贵——亚马逊售价 212 美元。</p>



<p class="wp-block-paragraph">说白了，盘和线大家都会挑，唯独盒子最容易被当成消耗品随手买。在固态涨价的当口，一个能把热导出去的壳子，保的是盘的速度，也是寿命。你手里那个盒子，拷文件时烫过吗？</p>
