[Solved] "sudo trimforce enable" not found

[Bustycat]

It's true a lot of modern SSDs have trim and garbage collection in their firmware. I haven't been convinced of the need to add OS-side trimforce for a few years now. No problems. Shows in System Report as Trim = No. Certainly don't experience quicker or slower boot times.

I think I need someone to explain why I'm wrong ...

It depends on what the user normally does on the SSD. Micron explains Trim for macOS pretty well. If the usages are light-weighted, enabling Trim on macOS may be marginal for performances, but it will be more helpful when the user frequently writes files to that SSD.

At least the difference about writing speed is noticeable for me, and Trim could help sustain the lifespan of an SSD longer.
