https://plumz.me/archives/1428 今天，我发现我被骗了。TRIM Enabled By Default For SSDs On Ubuntu 14.04 Trusty Tahr当时看到这个新闻还有点激动，因为不需要自己改了，于是... https://plumz.me/archives/1428/#comment-120339 2016-03-09T12:15:15+08:00 首先感谢你的脚本！这是我这两天的log内容： Sat, 05 Mar 2016 07:45:44 +0800 /: 219444977664 bytes were trimmed Sun, 06 Mar 2016 07:51:26 +0800 /: 3834396672 bytes were trimmed Mon, 07 Mar 2016 08:08:36 +0800 /: 2750799872 bytes were trimmed Tue, 08 Mar 2016 07:42:33 +0800 /: 219187560448 bytes were trimmed Wed, 09 Mar 2016 07:30:04 +0800 /: 2657067008 bytes were trimmed可以看出除了第一天和倒数第二天trim了220G以外（我的SSD是256G的）其他都是2-4G的级别。通过实验我发现，只要存在重启，重启之后的trim数据就会特别大。请问你出现过这种情况么？是不是我哪里设置的不对？$ uname -aLinux regis-PC 4.2.0-30-generic #36~14.04.1-Ubuntu SMP Fri Feb 26 18:49:23 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux$ cat /etc/fstab/ was on /dev/sdb1 during installation (SSD)UUID=b70fb8b0-60b3-4219-b244-ee4a692ef51e / ext4 errors=remount-ro 0 1 https://plumz.me/archives/1428/#comment-119428 2015-06-19T22:58:57+08:00 某些SSD确实会因为开启TRIM出问题呢，比如说https://blog.algolia.com/when-solid-state-drives-are-not-that-solid/ 提到的丢失数据的问题，讽刺的是这里出问题的是三星的SSD。默认关闭trim可以理解，不过根据品牌判断真是糟糕的主意。 https://plumz.me/archives/1428/#comment-119425 2015-06-19T10:32:09+08:00 intel大法好 https://plumz.me/archives/1428/#comment-119422 2015-06-19T06:48:29+08:00 是的，就是没有人权了。有本事你咬他们啊？
