It's a bit flaky... I have a number of USB sticks, ranging from a couple of Gb to 128Gb, USB2 and USB3. Some will work and some will not... and some will work some of the time. I've also killed a few completely in the process.Best answer is to try several, one of them WILL work. Don't expect opnsense to fill the SSD, it's not that large.
The image I posted earlier shows how much space opnsense takes up on the SSD after an install, before adding any other features. What you decide to add after install is up to you.
