100 % agree with what Marc wrote... What's the point anyway ? The real point...
Making an external HD to test, well ok, though I don't do that anymore, no time to lose actually, but I can understand it may be interesting.
Isn't the real goal to be sure any of your main and important apps work 100% ok ? For me it's Resolve-Fusion-Mocha-Motion-PS/AI and further a bunch of professionally reliable audio & video converters, for others it's something else but hey, you know where the real core of your activity is right ?.
Of course, I prefer if any desk jobs softwares work too (like Transmit for FTP etc etc) because I'm used too, but even for those I'd be ok to switch to another computer for non professional video making stuff...
Ventura ?
Ooops, sorry... It's because I'm writing on an El Capitan machine here and now
