I always made sure to keep at least a quarter of empty space in my SSD's in an effort to maintain their lifespan
but, recently, I realised that overprovisioning is not the same thing as keeping empty non-partition spaces when I installed Samsung Magician and used to actually increase the overprovisioning of my NVMe (That's only a partition of half its total capacity).

So this begs the question, how can I actually overprovision my SSDs in any Linux or BSD distro,
especially the upcoming HyperbolaBSD?

Thanks.

Does this even have any benefits?

AFAIK,

that is proprietary software...

Don't recommend it, but maybe someone else has other information?
