我为此抓狂不已。过去几周，我的系统偶尔会变得慢得令人无法忍受！我一直在努力找出原因，今天我想我找到了原因，但无法确定原因
因此由于某种原因，运行 hdparm 时我的 SSD 速度以 kb/s 为单位！
我停止了所有可能导致问题的程序，运行了 iotop，没有发现任何突出的问题
我尝试过更新，但那是个错误。我确实会定期更新这个东西，所以只需要进行几个标准的安全更新等。我花了 45 分钟，已经完成了 11%
我已经运行了 smartctl 并且驱动器完全正常。
CPU 负载约为 10%，并且还剩下大约 5GB 的 RAM（反正只有 16GB）
直到最近，一切都还好。我想不出我做了什么改变会导致这样的问题。
还有什么可能？病毒/恶意软件？
请帮忙！
如果有帮助的话，我在下面添加了 smartctl 的结果
