My main motivation was reliability. A couple of my machines are on 24/7, and even good quality microSD cards eventually corrupt. There is a performance increase, but it's not night and day.Jerry3904 wrote: Fri Apr 30, 2021 8:41 pm I've got to try this some time. It runs so well on a 32GB microSD that I am not tempted yet, but the day will come.
I have an NVMe drive in a USB 3 enclosure that i have tried with the Pi. It's not significantly faster that an SSD due to the USB bottleneck. It does use slightly less power, but the real benefit if you are doing a lot of testing is that you can write an image to it from a PC in less than one minute.
