[CentOS] To discard... or not to discard...

Hi,

I just recently read a post about SSD triming (discard vs fstrim):

 http://www.howtogeek.com/176978/ubuntu-doesnt-trim-ssds-by-default-why-not-and-how-to-enable-it-yourself/So far I used discard on all my SSDs.
Now I am wondering if it is really worth it to switch them all to a crontabed fstrim...
Anyone made the switch yet?


Thx,
JD
