Minimizing TBW Written with RAM Disk

I realized that Madmax plotter allows you to plot on Ram Disk in order to greatly minimize TBW written on SSD. I was thinking to use my main system’s 128GB RAM instead rather than adding wear on the Intel SSD S3-D4610 which has a TBW of 9.4 PB. My goal is to minimize the wear (tbw written) to a SSD, since a RAM disk practically does not experience any wear and tear/infinite life.

I actually have 2 PC systems, some spare samsung 870 EVO 500GB and a Hard Disk enclosure to USB that allows access to hard drives by connecting them to USB:

System A (Main System)

CPU: Ryzen 9 5900x (12 Core 24 Thread)
RAM: DDR4 Corsair 128GB RAM
Boot Drive: Samsung 970 Evo 1TB (TBW of 600TBW) 
Storage: Seagate 2TB HDD 
PSU: Seasonic Platinum 1000W

System B (Where Chia GUI currently is installed)

CPU: Intel Xeon E5 2697V2 (12 Core 24 Thread) 
RAM: DDR3 64GB Kingston HyperX
SSD: Intel SSD S3-D4610 (TBW of 9.4 Petabytes!), Only one SSD installed.
PSU: Seasonic Platinum 1000W
HDD: Several 10TB Hard disks

I was thinking instead if I can plot instead on my main System A using my 128GB of DDR4 RAM as RAM disk and then transfer the plots I make to System B by just moving the hard drives from the enclosure? With this way I’ll also be able to plot faster as well

But I do not want to wear down or add any writes to Boot Drive SSD (Samsung 970 Evo) on my main System A

Recall that in Madmax plotter readme:

<tmpdir> involves 25% of all writes written and needs about 220 GiB of space
<tmpdir2> involves 75% of all writes written and needs about 110 GiB of space

So I will then instead install a Samsung 870 Evo 500GB on my main system and specify it as while my RAM disk on my main system will be ?

With this setup, I should not experience any writes done to my Main system’s samsung 970 EVO ssd? (I don’t want to burn my main system SSD out)

Then if I am going to do this, if my aim is to make NFT Plots on my System A:

I should then get the farmer and pool public keys from System B 
via chia plotnft show command?

And that's what I input in running madmax plotter on System A?

Also are there any caveats I should know when making and plotting towards a RAM disk?

that’s right, get the farmer and pool public keys from System B

actully, A, B is all is OK, but you should choice only ONE, but we always use the one bind to the GUI
