I’ve got a ThinkPad T410. I got it off craigslist in what was a somewhat shady transaction. Regardless, it came with a 300GB spinner. Not interested in finding out how much life was left on it I got a solid state replacement from NewEgg for “Cyber Monday”. A 240GB Intel one for $110, that’s less than 50 cents per GB!
The spinner has a single unencrypted partition with Arch Linux running on it. I wanted to run Arch on an encrypted partition. The main reason: If it’s ever stolen I don’t want to have to worry about any of the data on it. Bonus reason: Geek/spy points.
So, while there are excellent guides for installing Arch, and setting up encryption, and optimizing an SSD, there don’t seem to be any combining the three. In reality it’s not that much more difficult, and if you are motivated to setup encryption on Linux in the first place you probably know what you’re doing. Still, I was disheartened a bit at the lack of information so I decided to note how I went about it in general.
