Ubuntu 14.04 LTS supports TRIM on SSD drives

Instead of being happy, I'm rather horrified to learn that this hasn't been supported until now.

Mountain out of a mole hill. Glad someone got some sense knocked into them and enable this flag by default, but Linux has supported TRIM for a long time. It was just a matter of adding the mount option.<p>And by the way, last I checked there&#x27;s still a long laundry list of non-default incantations to optimize SSD usage on Windows, where you&#x27;re stuck harder because you don&#x27;t have control over things like the I&#x2F;O scheduler.

Trim has been already supported for years. It just was not on by default.

So it&#x27;s news that a feature supported on other platforms for anymore from months to years [1] will be supported on Ubuntu 5 months from now?<p>Huh. Colour me unimpressed.<p>[1] <a href="http://en.wikipedia.org/wiki/Trim_%28computing%29" rel="nofollow">http:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Trim_%28computing%29</a><p>Full disclosure: I was an Ubuntu user and tester (signed the c-o-c years ago) for years, switched to OSX on an Air a few months back, and cannot imagine going back to an inferior user experience on inferior hardware. Open source OS was an interesting experiment, begun to ensure access to my data, but given cloud apps with export capabilities and native OSS apps, I cannot imagine wanting to suffer another moment with an OSS user desktop. Server maybe. But even there my conviction levels drop....

That reminds me that I need to enable TRIM on my Ubuntu SSD. I usually do it, but I had forgot to do it with my recent install. I&#x27;ve used this article in the past (<a href="http://www.howtogeek.com/62761/how-to-tweak-your-ssd-in-ubuntu-for-better-performance/" rel="nofollow">http:&#x2F;&#x2F;www.howtogeek.com&#x2F;62761&#x2F;how-to-tweak-your-ssd-in-ubun...</a>). It is fun to measure your IOPS before and after.

tl;dr &quot;Embarrassingly late, but at least in time for 14.04 LTS.&quot;

Ubuntu 14.04 LTS has TRIM support for SSD drives out of the box. No need to setup a cron with the &quot;fstrim&quot; command or set the fstab &quot;discard&quot; option, like in earlier versions.

Can anyone comment on the contrary advice here, which is referenced from the debian SSD Optimization wiki page?:<p><a href="http://www.spinics.net/lists/raid/msg40916.html" rel="nofollow">http:&#x2F;&#x2F;www.spinics.net&#x2F;lists&#x2F;raid&#x2F;msg40916.html</a>

Now, if they can adopt F2FS (flash friendly file system) for SSD&#x27;s, that would be neat, too. On Motorola&#x27;s latest phones and in benchmarks it shows substantial performance difference (~50 percent more on average or so).

Does this support encrypted drives? I had a really big pain trying to support an encrypted ssd under rhel 6, I gave up after an entire day of work.

What a terrible linkbait title.<p>This implies that Ubuntu hasn&#x27;t &quot;supported&quot; SSDs and the discard mount option. That&#x27;s inaccurate, TRIM has been in Linux since kernel 2.6.28–25 released in Dec 2008.<p>A more accurate title would be &quot;Ubuntu 14.04 adds fstrim cron job, so you don&#x27;t need to mount with discard anymore if you don&#x27;t want to&quot;.

Wondering when they&#x27;re going to support Trim for Software Raid?

This reminded me to do the chore again.<p><a href="http://img23.imageshack.us/img23/4143/1zx2.png" rel="nofollow">http:&#x2F;&#x2F;img23.imageshack.us&#x2F;img23&#x2F;4143&#x2F;1zx2.png</a>
