[SOLVED] Trim on SSD

[Wirezfree]

Thanks Dave,
I followed your tips and this is what i see.
Any idea what the (16 block) limit would mean.
My drive is a OCZ-Vertex4 120GB
I run different version of Linux on my main pc and was with the understanding that trim was handled my the kernel without any necessary input from the user.
Maybe i am wrong on this.
Thanks again for your help.

Hi Bill,

Not sure what the blocks mean, I have seen outputs with 4, 8 and now yours 16.
Maybe it's related to how many blocks it can Trim at a time.?

The outputs all look O.K, So Trim appears to be supported and working with your SSD
Really not sure why the test didn't work.??

If you look at the links I sent, they give details on how to set-up Trim with a daily Cron Job
That seems to be the preferred/most recommended way to Trim.
From what I have read, it appears that if you add it in fstab it can add an overhead,
because it Trims every time you delete something.
