简介固态硬盘都有使用时长和写入量的限制，因此，有必要进行寿命的检测。 SmartControlSmartCtl（S.M.A.R.T 自监控，分析和报告技术）是类 Unix 系统下实施 SMART 任务命令行套件或工具，它用于打印 SMART 自检和错误日志，启用并禁用SMRAT自动检测，以及初始化设备自检。 SmartCtl 对于 Linux 物理服务器十分有用，在这些服务器上，可以对智能磁盘进行错误检查，并将与硬件 RAID 相关的磁盘信息摘录下来。 安装 sudo apt install gsmartcontrol 如果不使用图形界面，可以使用如下命令。 sudo apt install smartmontools 执行查看命令。/dev/nvme0n1 是硬盘的路径。 sudo smartctl -a /dev/nvme0n1 输出信息。加粗标红的就是硬盘写入量和读出量。 smartctl 7.1 2019-12-30 r5022 [aarch64-linux-5.4.18-35-generic] (local build)
