<p class="wp-block-paragraph">你把重要资料拷进一块固态硬盘，塞进抽屉，心想这下踏实了。How-To Geek 撰稿人 Monica J. White 的提醒可能会让你后背发凉：固态盘擅长的是&#8221;经常读写的快存储&#8221;，而不是&#8221;放着不动的长期归档&#8221;，这两件事完全不是一回事。</p>

<p class="wp-block-paragraph">原因在硬件本身。固态盘靠 NAND 闪存单元里存着的电荷来表示数据，通电时主控会在后台跑检查、用 ECC 纠正小错误、把状态变差的块重新映射走。断了电，这套自我维护全部停摆。西部数据的资料也写明，随着擦写次数（PE 周期）增加，数据保持能力会随之下降。</p>



<p class="wp-block-paragraph">有人真做过实验。YouTube 频道 HTWingNut 连续两年跟踪四块廉价 TLC 固态盘，那些早已超出建议写入量的盘，断电搁置两年后出现了数据损坏迹象。样本量小说明不了行业趋势，但四块盘无一例外都在退化。对比之下，Backblaze 统计的 3144 块固态盘年化故障率只有 0.90%——那批盘天天在跑，恰恰印证了同一个道理。</p>



<p class="wp-block-paragraph">最麻烦的地方在于<strong>它坏得悄无声息</strong>。盘还能正常挂载、目录也在，打开文件才发现已经损坏，而这时候往往已经晚了。</p>



<p class="wp-block-paragraph">说白了，别把唯一一份备份押在一块断电的固态盘上。真正管用的是 3-2-1 原则：三份副本、至少两种设备、其中一份放在别处。冷存储用机械硬盘更便宜，数据量大的话组个 NAS，用旧电脑改一台都行；固态盘更适合当&#8221;随时要取的工作盘&#8221;。</p>



<p class="wp-block-paragraph">如果你手头确实有固态盘在存归档数据，做法很简单：定期插上电跑一遍完整读取校验，对不可替代的文件比一次校验值，再用 CrystalDiskInfo 这类 SMART 工具看看磨损和错误计数。抽屉里那块盘，多久没通电了？</p>
