From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

lsblk --discard
to check support and non zero DISC returns mean TRIM supported. ~~And then you need to adddiscard
options to supported partitions in /etc/fstab.~~ Then enablefstrim.timer
withsystemctl
. And it will automatically run weekly. You can edit the run frequency by editing thefstrim.timer
file.This is what I have done from reading Arch wiki. https://wiki.archlinux.org/title/Solid_state_drive#TRIM
You typically use either
discard
or thefstrim.timer
, but not both at the same time.Using the
discard
option means that trims are being done on the fly every time blocks are deleted, usingfstrim.timer
means that trims are being done periodically. The former carries a performance penalty, so it's usually not recommended unless you need it (for example, if you regularly do huge amounts of writes and deletes on this drive).Thanks for this. I got confused writhing this as I used
discard
on my previous install.
