Linux settings for SSD drives

leave a comment »

I recently bought an SSD drive (a Samsung 840 Pro series MZ-7PD256BW) for my root, boot and home partitions. The speed increase and system responsiveness of my Ubuntu Desktop system is really impressive; that’s what I call money well spent!

Here are a few settings to change in your Linux system to increase the lifetime of your SSD drive:

  • enable TRIM in /etc/fstab (add the ‘discard’ option to each SSD partition)
  • add the ‘noatime’ and ‘nodiratime’ options in /etc/fstab
  • enable TRIM in /etc/lvm/lvm.conf (change the value of ‘issue_discards’ to 1)
  • move /tmp to RAM (add the following line to /etc/fstab: tmpfs /tmp tmpfs size=512m 0 0)
  • minimize the use of swap memory (set vm.swappiness=1 in /etc/sysctl.conf)
