As I wrote yesterday, I migrated my Linux install from an HDD to an SSD. That runs great by default, but you should add the
discard argument to the relevant entries in
/etc/fstab to enable TRIM support. Long-time SSD performance should remain great thanks to that simple action, which in my case looks like this:
# /dev/sda1 UUID=b8024bbf-9d29-417d-b6eb-ef87d0d586ec / ext4 errors=remount-ro,discard 0 1 # /dev/sda2 UUID=30efde45-b883-464d-966c-605e091078b9 /home ext4 defaults,user_xattr,discard 0 2
Some also recommend to set
noatime to prolong your drive’s life, but since
relatime is the default these days that doesn’t seem necessary to me. However, what you should probably do if you’ve got a sufficient amount of RAM, is to mount
/tmp in it.
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0 tmpfs /var/tmp tmpfs defaults,noatime,mode=1777 0 0
You can do the same thing with your logs, but I’m not too sure whether I want to do that myself, even if it would cut down on writes.
On my new Wheezy install, I switched to a daily cron job for better performance.
