我刚刚在电脑上安装了一块新的三星 970 EVO Plus NVMe，作为大文件的存储驱动器和一些交换空间。我有一块华硕 Rampage IV Extreme 主板，没有 M.2 插槽，所以我把它放进了这个PCIe 适配器将其连接起来。
我已经编写了文件系统并格式化了驱动器，fdisk没有任何问题，并且将分区添加到我的/etc/fstab：一切正常。
当我尝试使用它时，问题出现了：如果我尝试一次性复制任何大于 4-5 GB（总计）的文件，驱动器会断开连接，然后我就无法在 、 等中找到它。lsblk但是blkid，如果我lshw在其上运行，条目会（在中断后）从

我不知道是什么原因造成的：大概是控制器在持续负载下过热等，或者主板没有向 SSD 发送足够的电力？也许是适配器的问题？我已经在所有可用的 PCIe 插槽以及一个装有以太网卡（工作稳定）的插槽中测试了这个问题，每个插槽中的问题都完全相同。不幸的是，我不知道如何检查是否存在这些情况，而且谷歌搜索也没有返回任何有用的信息。
答案1
事实证明，这只是 PCIe - M.2 适配器的问题。购买新的（不同型号）即可解决问题。
