[SOLVED] Trim on SSD
#2

Instead of o,s i got a screen full of f,s.
Attached is my new fstab file.

Hi,

First thing to do is check if your SSD actually support Trim?
Code:
sudo hdparm -I /dev/sda | grep "TRIM supported"

It should return something like this if it does
Code:
dave@asus-mini-1:~$ sudo hdparm -I /dev/sda | grep "TRIM supported"       *    Data Set Management TRIM supported (limit 8 blocks)
dave@asus-mini-1:~$

If it does not return anything, it does not support Trim,
If it does, try
Code:
sudo fstrim -v /
It should return something like:
Code:
/: 856668590 bytes were trimmed
It may take some time.

Here are some items on Trim, it appears there are differing opinions
on if should be done in "fstab" or doing it in "Daily" Chron job.

At present I just do it manually with the
Code:
sudo fstrim -v /
