I believe SSDs are soldered onto the motherboard for M1 laptops + M1 mac mini, I wonder how bad of an issue it is when considering used M1s.

Can’t imagine it’s a big issue; the SSD on my 7.5 year old Skylake MBP is cheerfully claiming 96% lifetime remaining, and seems to be fine. The days of SSDs self-destructing after a couple of years seems to be largely behind us, at least for consumer applications; even low-end stuff has a decent practical lifetime these days.

Very much depends how it was used. You might be able to tell with the SMART report.
