I seen the posts about using ramdisks, but haven’t seen how big it needs to be. I’m running with 16 GB of system ram. I have no desire to buy more. Is a 1GB or 2GB ramdrive enough, if I only run one stream at a time?
In testing I have never seen any advantage to a ramdisk for Plex. In my experience Plex just does not gain much from using a ramdisk.
I’m not after a performance improvement. I’m looking to save some wear and tear on the SSD.

You do not have to worry about wear & tear on you SSD if you run Plex from it. You will need to move the plex metadata folder off to a secondary drive. IF you don’t then 16GB RAM ain’t gonna help you with squat.
SETTINGS->SERVER->GENERAL->The path where local application data is stored
Oh yeah, you will need to click ‘Show Advanced’ for that option to be visible.
You misunderstand. If the secondary drive is a ramdisk in main memory I can do as you suggest, without having any performance hit from moving the directory to an actual hard drive. But I would want that ramdisk to be only large enough to serve its purpose, while leaving the rest of my RAM available for program execution use.
How that I have explained fully what I am pondering, does anyone know the minimum size necessary to accomplish what PLEX needs to do, while optimizing my RAM usage?

It totally depends on the size of the source file you’re transcoding - not something anyones knows but you. You need to be able to store the total size of all your simultaneous transcodes at the target bitrate you are transcoding them to. 2Gb sounds way small if you want to play with HD - might be ok for some low end SD.
From that answer, it sounds like a RAM drive would be impractical unless you’re running 32 GB of main memory and up.

Likely yes. Mine is 96Gb, but I do a lot more than 1 simul transcodes. Unless you have the ram sitting around, given the cost it’s prob better just to trash the SSD.
