Help with dual-boot speeds

Hi, for the first, I apologize for my lack of English.

I am a owner of a 15” MacBook Pro 2018 with 512 GB. Right now am running Mojave (not Catalina because I use Adobe programs and have heard about some problems), and also Bootcamp where I have 80 GB.

I know it sound a bit strange, but I have always wanted a multi-wide system, and I really want to do something about I know.
I am talking about following systems:

- Mojave (main system, but would be converted to Catalina at a short time
- Beta-system for Mac
- macOS High Sierra
- Windows 10
- Windows 8 (if possible)
- Windows 7 (if possible)
- Kali Linux

For all that, I need some space. The original plan was a Samsung T5 SSD, with 80 GB For each system.

The problem is, that I have about the SSD isn’t so fast again. That leads me to three opportunities:
- Still use the T5
- Buy a X5
- Give 25 GB to each system, from my main system with
512 GB. That is 150 GB at all. All the stuff that is not the system, would then be placed on a T5, where I wouldn’t feel the speed change

What is the best idea, and is there any other opportunities, where I don’t need to buy a X5?

Sounds like virtual machines might be a way to go?

You can buy a cheap external hard disk with 4TB+ and move the virtual machines to the slow external drive when you're not using them.

I use a T5 for windows 10. It works pretty quickly for me. The only time I really notice it's slower than my internal 2017 iMac is for larger file copies, which isn't very often for my use.

It comes down to what kind of performance you need. T5 is plenty speedy for gaming, in my book, and probably good for anything short of 3D modeling, or video editing. If you need more performances an X5 would probably be the best option. I don't think most of those OSs will function very well with less than 30GB working space (and definitely wouldn't have room to install performance hogging apps). Otherwise VMs are a pretty solid, ad hoc option, but definitely not high performance.
