Faster drive for boot or storage - directstorage

[Shott92]

So speccing up a build to help me do some AI driving simulation for my uni course.
Wanting to save a couple of quid while getting best performance, also it appears MoBos may be limited in number of pcie5 slots anyway.
These simulations are super compute intensive and can an hour to run just a 1 minute, simulation. So every little helps, but I'm still on a budget.
So would I use a pcie 5.0 SSD as my boot and program drive (which will have Clara simulator and airsim installed) and then have my footage, maps, programs installed on the PCIE 4.0 drive, or the other way round.
Or should I have it all on the same drive so that there isn't any shared I/O bandwidth?
I'll be looking at a 12700/13600 or 6600X/6700X (if available at launch), with a RTX4070/RX7800.
Two SSDs probably one 2TB and one 500 GB
And then as much DDR5 ram as I can afford.
Any help or guidance is greatly appreciated.
Thanks

Hi guys thanks very much for the feedback, so my thoughts was that the way the simulation will run, is it will build a map from the SSD, I assume mostly held in VRAM, but a full map will be too big, especially if all assets are turned on.
It will then try to run my code, which will be a mix of standard image manipulation and performing mathematics and matrix functions on the image, which will be converted into essentially a data array/ table, with raw data, and some AI workloads on top, these will both mainly be done with GPU enhancement.
Again due to size it won't fit maps, simulation assests, data outputs and all these data frames into VRAM or RAM so I suspect it'll have to dump to the SSD at pretty regular intervals.
But I'm not certain, i think what I'm going to do is build the PC with a single Samsung 980 pro.
And see what the resource utilisation is and if the I/O is high and I'll try to remember to update this post and let you guys know the outcome, but the build will be a couple months away yet as the rumours suggest the rtx 4000 and rx 7000 will offer significantly better value than current cards.
Thanks again everyone
