Nowadays the cost of a USB is really cheap,you can find 64 GB ones for 5-10 USD in Aliexpress,you can make cloning of them after you achieve the best possible options in your OS with Acronis (software for cloning disks) and you can have like 3-4 of them as backups when bad things happen.Normally they last long enough as I have one running from 2018 and no problems so far.So yes nowadays the technology has evolved that much that they are reliable,I am talking about branded ones like Sandisk,Kingstone etc and not the Chinese non-branded USB-s,those probably won't last long.

Small SSD are damn cheap.
I have build my own Windows OS and stripped of everything that i don´t need -> it writing nothing constantly to the drive.
And there are also Win10 images out without installation, which will boot and run from USB flashdrive -> this versions also don´t write constantly logs.
HiveOS is writing constantly a log, you must deactivate it, if not it can kill your flashdrive. So not all miningOS are for flash drives out of the box.
You must not have read the “specifically designed to run off flash drives”…HiveOS i wouldnt run for anything. I use Ethos and mmpOS….both are designed for flash drives specifically.
As for mining on windows……i dont run windows. I prefer oses where i am in control of the computer.
But to each thier own.
