== Summary ==
Enabling fstrim.timer will cause fstrim.service to execute weekly,

A bit late, but I just want to say thank you, Chris, for pushing this forward. TRIM by default is long overdue in Fedora, I think. It has a big impact on SSDs speed and longevity. I'd love to see mounting with "discard" by default, but I understand there are various issues with poor TRIM implementations. Weekly discard of empty space is the next best alternative.


What does windows do? Is it the equivalent of the discard mount option or is it more like fstrim?

If it is the former then we should do the same given that most hardware out there are used that way if that's the case.
