Re: [Trisquel-users] Does Trisquel 8 have TRIM on by default? And does it matter?

I had already checked and /etc/fstab doesn't have "discard" there. I just  
forgot to mention that in my post. Actually nor seeing it there was the  
motive for my post. Thanks for the link, it clarified to me that I can just  
every now and then run my fstrim command and it will be good to go.

Thanks!

Found it

https://libreboot.org/docs/gnulinux/encrypted_parabola.html

However I am unsure as if running the command I did (sudo fstrim -v /)  
actually raises any security issues or not... Or if it was even beneficial  
from a performance standpoint given that I got the same results in sudo  
hdparm

[Trisquel-users] Does Trisquel 8 have TRIM on by default? And does it matter?

Hey everyone,

So, I noticed my SSD was getting a little filled up (only 70GB free in 256GB)  
and decided to read about how much it would affect the performance of my  
machine.


From what I understand YES, SSD shouldn't be left nearly full otherwise it  
affects performance, due to the way SSD works. With that in mind I run:


sudo hdparm -Tt /dev/sda

And got this:

/dev/sda:
 Timing cached reads:   3644 MB in  2.00 seconds = 1824.91 MB/sec
 Timing buffered disk reads: 798 MB in  3.01 seconds = 265.42 MB/sec


After that I run:

sudo fstrim -v /

And got this:

/: 83,2 GiB (89301729280 bytes) trimmed

However running the previous command again:

sudo hdparm -Tt /dev/sda

gave me the same result as before. So, does it even matter if we use TRIM or  
not?


Also, I read that Ubuntu 14.04 has TRIM on by default. Shouldn't Trisquel 8  
have it be default too? And if so, why did it allow me to TRIM 83,2GB when I  
run it manually?


I have a vague memory of Libreboot systems having some issues with TRIM and  
SSD... But I can't find it anywhere online. Maybe I am mistaken. If someone  
knows about that I will be thankful too.


Thanks!!
