    smartmontools

    smartmontools 是一个可以用来查看 SSD 写入量的软件。 可以从 https://www.smartmontools.org 了解如何安装。 在 Windows 操作系统上,以管理员模式运行安装目录下的 smartctl (Admin CMD): 这是我的 Toshiba Q200EX 240GB , ID 为 173 (AD)的那行的值,可以看出大致的使用量,我的这个盘,已经用了好几个月了,新的时候,是 200,现在是 196。 往下翻,可以看到通电时长和通电次数: 往下翻,会看到: 其中的 0x008到 0x030 几行比较关键,比如,这个盘的数据写入量为: 8777365570*512/1024/1024/1024/1024= 4.08 TB 再往下翻,会看到 0x07 的值,为使用百分比,这个盘,意境使用 4%的了,N表示目前是正常的。 由以上数据,可以推测出,这个盘的最大使用量是 102TB。 在 Ubuntu 上使用: wget https://builds.smartmontools.org/r4731/smartmontools-6.7-0-20180419-r4731.src.tar.gz tar zxvf smartmontools-6.7-0-20180419-r4731.src.tar.gz cd smartmontools-6.7 ./configure make sudo make install 配置时,可能会遇到可以忽略的警告: configure: WARNING: This version of smartmontools provides NVMe support which is still EXPERIMENTAL. NVMe devices are not yet included in smartd.conf 'DEVICESCAN' and 'smartctl --scan' unless '-d nvme' is specified. Use option '--with-nvme-devicescan' to include NVMe devices. Use option '--without-nvme-devicescan' to suppress this warning. 然后开始扫描挂载的硬盘 sudo smartctl --scan 系统盘一半是 /dev/sda, 查看它的使用情况 sudo smartctl -x /dev/sda uuu@uuu:~/smartmontools-6.7$ sudo smartctl -x /dev/sda smartctl 6.7 2018-04-19 r4731 [x86_64-linux-4.15.0-20-generic] (local build) Copyright (C) 2002-18, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Device Model: FSX-120GB Serial Number: 6212161000778 LU WWN Device Id: 6 212161 000770000 Firmware Version: 5.2.4 User Capacity: 120,034,123,776 bytes [120 GB] Sector Size: 512 bytes logical/physical Rotation Rate: Solid State Device Device is: Not in smartctl database [for details use: -P showall] ATA Version is: ATA8-ACS, ACS-2 T13/2015-D revision 3 SATA Version is: SATA 3.0, 6.0 Gb/s (current: 6.0 Gb/s) Local Time is: Fri May 4 23:41:36 2018 CST SMART support is: Available - device has SMART capability.
