Ask HN: How do you format / speed up a SSD?

Vopt is an excellent defrag/trimmer/cleaner for Windows, now made freely available by the author. https://www.majorgeeks.com/files/details/vopt.html

sudo fstrim / -v

spinrite from grc.com works on SSDs. It can speed them up, from what Steve Gibson says. I don't have a way to measure my SSD speed, so I can't provide evidence.
