[SOLVED] Trim on SSD

[Wirezfree]

I have followed the instructions in  the manual to see if trim was working on my ssd.
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 /
