I recently invested in a SSD for my laptop, I bought the Samsung 500Gb 860 Evo, which I choose specifically because the sales blurb talks about improved Linux compatibility with regard to TRIM.
I decided to start with a fresh install of Ubuntu 17.10, rather than to try and migrate my existing set up. I went with the full disc encryption.
Everything seems to be working fine and fast but I see there are a few additional recommended steps for SSD optimization. I have added noatime and noadirtime to my /boot reference in /etc/fstab. I understand that I don't have to do anything with TRIM, because it should already be enabled for this drive. And that leaves removing my swap partition. Which I'd be happy to do (I've got plenty of RAM), except I think that the drive encryption has confused matters...
Here is how my drives are laid out. This is the setup that the Ubuntu installation process automatically created for me.
So as well as a 17GB swap partition, I also have a 17GB cryptswap partition. Should I remove both? Would that break my encryption? Are there any other issues I need to consider? I'm not too far into the process of setting up my machine, so I would consider another fresh install with different settings if that is advisable.
Thanks in advance.
