Drive read/write speeds for running windows

Hello everyone, again, I made a thread yesterday about dual booting with an external drive and got answers, but another big question arose so I feel it needs its own dedicated thread.

So I'm trying to find the right drive for my USB-C only 2017 mbp. Obviously, because I'll be running windows on a drive, the read and write speeds must be fast. Does anyone know if a drive with a clock speed of aprox. 130mb/s would be enough? Or would I need to invest in the Samsung T5 with high 400s mb/s read/write speeds.

Would very much appreciate the help, thanks again.

It really doesn't matter. The USB 3.1 spec has a theoretical speed of 10 Gb/s (1250 MB/s) but practically you'll get around 7 Gb/s (875 MB/s)...

The read speed of SSDs will be faster than write speeds and so if you have 400 MB/s read and say 250 MB/s writes that means that you'll load things pretty quickly off the drive and go. If you use a regular spinning (7200 RPM) HDD, you're around 130 MB/s read and slower writes. This just means that things will work more slowly, but still work.

I used an external SSD in the past to run Windows through VMWare Fusion and that worked totally fine.
