Is it better than fstrim.timer mentioned in this thread?
Some years ago there was a warning on the
<https://wiki.archlinux.org/title/Solid_state_drive/NVMe>
page that Intel did not recommend continuous TRIM aka discard. Currently
there are some words against discard in
<https://wiki.archlinux.org/title/Solid_state_drive#Continuous_TRIM>.
Do you have more details on this story, what was behind Intel suggestion
and what has changed since that time?
As to secure erase, I have seen comments claiming that sometimes it
helps to recovery performance degraded after some period of usage. I
have not tried to collect details if it is related to specific models or
to low end drives.
