I just recently set up a new PC with an SSD/HDD combo; my Linux partition on my SSD is mounted as /
with /home
mounted on my HDD.
I have the noatime
and discard
flags set for my SSD in /etc/fstab
, but just to see what would happen I ran fstrim from the terminal when I rebooted a few times.
When I do it, the return is:
~> sudo fstrim -v /
/: 54.9 GiB (58889682944 bytes) trimmed
for reference, 54.9GiB is also the amount of free space on my 60GiB partition.
Is my entire partition being rewritten between each boot, and should I be concerned for my SSD? Is this just a result of having the discard flag enabled AND using the fstrim
command? Should I only use one TRIM method and not the other?
