Recently I ordered a new laptop and, for the first time I chose to have an SSD. So I did some research beforehand including some questions to the list. So I came across the trim command, which it seems is necessary to keep your SSD in good nick. I found lots of information on line, some of it conflicting of course. There seem to be 4 ways of implementing trim. 1. Running the fstrim command manually as and when. 2. Adding the instruction to rc.local. 3. Setting up a cron job, or using one that is already installed. 4. Making a change to fstab. No 1 was not recommended. Big Apple among others put an end to that one. No 2 was favoured by some, but not by others. No 3 My distro is Xubuntu 14.04 LTS which already comes with a cron job set up. This was described as 'not the optimal method'. No 4 This was the preferred method by some, not by others. So, in the end, this is what I have done ..... I moved the cron job, cron.weekly/fstrim to another folder, effectively stopping it from running. I added discard and noatime to the relevant line in fstab. Of course, early days yet, but it all seems to be working well. The articles I read also warned about not defragmenting the disk, but I assume that is Windows only, so I can ignore that. If anyone has any advice, comments etc I will be grateful. Thanks Neil -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
