Even though they are written to different area’s of ‘disc’, doesn’t an SSD write to any unused portion rather than in a circle as on a ‘spinning’ drive?
I thought SSD didn’t overwrite stuff ‘all the time’ in same area but sequentially used all available space so drive lasts longer (where an old style spinning disc would start at middle and work outwards.) This should mean any bad sections will automatically be skipped?

Yes. That is pretty much the case.
