Hi everyone,

I discovered a little trixk that will help keep a SSD clean and maintained
under Linux.

I ran "fstrim -av".

===
When you delete a file on a normal filesystem, the OS just marks the space as 
"free," but the SSD itself doesn't know that. From the SSD's point of view, 
those blocks still look occupied.

fstrim sends a message to the SSD saying:

"These blocks are no longer in use -- you can wipe them internally whenever 
you want."

That lets the SSD:

    clean up unused blocks

    prepare them for fast future writes

    reduce write amplification

    maintain long-term performance
===

My result?

I freed up 406GB of space on a 512GB SSD.

The speed-up was immediately noticable.
