you're confusing TRIM (which tells the ssd 'this block no longer contains data' assisting the garbage collection algos on the ssd) with defraggingmetamorphosis wrote: ↑Thu Mar 21, 2019 8:28 am Every modern OS worth it's salt does a small amount of defragging to an SSD. This is important and should happen. There are multiple technical reasons why this should happen. Unfortunately there are some dumber OS's (*cough*osx*cough*) where no manual tool is available.
Also OSX/macOS has always supported TRIM (since apple released macbooks with ssds) - issue was early on MacOS would _only_ do TRIM on 'genuine apple' drives, so if you retrofitted your mac with a ssd you got no TRIM. There were various workarounds for this, and more recent versions of MacOS allow you to explicitly enable TRIM (at your own risk) via the 'trimforce' command
