I noticed, in the nixos-hardware link , that
services.fstrim.enable for Dell XPS 13 9310 but not for Lenovo T480s. I understand that the option allows better use of the SSD is that correct? Despite being different manifactures, they both have SSD. Why this discrepancy?
Probably just an oversight?
Yeah it looks like that profile is intended to be a starting point and has been minimally maintained by only one person, who does enable fstrim elsewhere in their configuration.
I’d recommend submitting a PR to add at least
