Ubuntu Doesn’t TRIM SSDs By Default: Why Not and How To Enable It Yourself

Ubuntu wants to enable TRIM for SSDs by default in Ubuntu 14.04. In other words, Ubuntu isn’t already using TRIM, so your SSD is slowing down over time. But why isn’t Ubuntu already using TRIM?

This news will likely come as a surprise to many people, who assumed that Ubuntu and other Linux distributions were already using TRIM. TRIM prevents SSDs from slowing down over time and is a necessary part of SSD maintenance.

Links: How to extend the life of the SD card on a Raspberry Pi (or similar device)

People are using the Raspberry Pi for many applications these days, including as a VoIP PBX server based on Asterisk. One thing that many people forget is that you can only write to an SD card a limited number of times before it fails. Asterisk in particular likes to write a LOT of information to log files, and let’s face it, if you are honest and you are like 99% of Asterisk system administrators, you will admit you never read them unless perhaps you suspect there is a problem with your system. Yet every one of those many writes reduces your SD card’s lifespan by a small amount.

So with that in mind, here are links to a few threads that may or may not be helpful, in no particular order:
