Raspberry Pi: Extending the life of the SD card

I realized after posting this that it is a repeat post, but those new to the Raspberry Pi might not have seen the original post, so here it is again:

SD cards are said to have a finite life. If you are planning on running a Raspberry Pi 24x7x365, there are some steps that you can take with GNU/Linux to extend the life of the card: here are some ideas.

The Raspberry Pi is an incredible little computer made up of a components and connectors on an unfeasibly small printed circuit board that is approximately the dimensions of a credit card. Depending upon your intended use, your Rasberry Pi may have a keyboard, monitor and mouse added. Regardless of your intended use, you are going to need an SD (Secure Digital) card on which to install an operating system.

This tutorial describes how to install an operating system onto an SD card for use in your Raspberry Pi.

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:
