So that means I can just enable it from terminal, and there is no risk. I was just worried because on few reddit threads, people complained about slow performance and data loss, after they enabled the TRIM.
Are there any noticeable difference in performance, if it remains disabled?
All new SSD will perform well, it is over time when allocated blocks and pages become used, you start to see a loss of performance.
You will have to do your own research and make your own decision on the issue—ultimately it is your loss or gain.
"TRIM doesn’t obviate the need for garbage collection—it works with garbage collection to more properly mark pages as stale. And you don’t need TRIM for garbage collection to work—but TRIM makes an SSD’s garbage collection more efficient."

There is much information to sift through.
I can say new Apple computers that ship w/ SSD have TRIM enabled by default.
Apple just within the last couple OS X, supply the TRIM command in terminal for 3rd party SSD (eliminating the need for 3rd party methods to enable TRIM) this should tell you something about demand of this functionality.
OWC a reliable Mac parts suppler says you can or cannot enable TRIM on their SSD—suppossedly they say their SSD do fine without TRIM. http://blog.macsales.com/31602-owc-ssds-built-to-perform-with-or-without-trimfor ce-command
I have also read reports here—in the ASC—where SSD that have bogged down over time and use, and by enabling TRIM has miraculously restored speed and performance.
I can say personally came to my own conclusion and enabled TRIM on my OWC Mercury EXTREME Pro 6G 480GB SSD as soon as I installed it new—and no issue to report.
All drives will fail over time, so always, always have a current backup plan in place no matter what you decide to do moving forward. How to create a boot clone
