    I had a Samsung 830 512GB SSD in my early 2011 MBP since May of 2012. I initially recall Samsung support telling me to Enable TRIM, it will prove beneficial for the drive. With different, various OS updates, TRIM was disabled.... as I believe anyway. Since my El Capitan install a few days ago, I enabled TRIM in the terminal window 'sudo trimforce enable', reboots, system report shows 'TRIM Support: Yes' so all was good, I was further experimenting. I actually think my MBP sped up after a few days, bit it might have been a placebo thing... right? Speed tests actually improved!

    But back to my main concern.

    I CCC'd to a new Samsung 850 Pro 1TB SSD. Installed the new drive. All my settings carried over of course. I opened a terminal window, and went through the disable TRIM motion 'sudo trimforce disable' it goes through the process, says successful or something of that nature, reboots... but when I check system report again....
    'Trim Support: Yes'

    It did NOT disable... despite saying it did!

    Help, any suggestions, tips, know ways of resolving?__________

    As I understand from reading quite a bit on the new Samsung 850 Pro drives... the controller does a good enough job with garbage control, Toms Hardware also ran some tests on the 850 Pro 1TB and it did better without TRIM, faster overall.

    Because I should be allowed to do so. The point is the OS should allow me to toggle it off, disable, toggle it on if I choose, enable. I don't know yet if it's advantageous for me to have TRIM enabled for my drive yet or not?! It's a 50-50 in regards to opinions as I read about it. The MBP I have was initially set TRIM Support: Yes when I bought it, that was with a 128 GB IBM drive. I put a Samsung 830 in it, left it as TRIM Support: Yes, but subsequent OS upgrades changed all that.... My hands are now tied, if I want to disable TRIM.... I can't! With El Capitan, I am suppose to be able to have the freedom of choice... I have no choice.

    I'm sure you could turn it off but it shouldnt affect you in anyway. Just reinstall it.

    Well....Yeah.... I may just leave it as is. When I experimented with TRIM on the Samsung 830 drive I had installed at the time (El Capitan) and CCC'd my drive while TRIM set YES. It seemed to have froze that setting when I CCC'd to the new drive.
    I had the early MBP in for service recently, it had a failed logic board. Apple had an extension warranty program to cover the costs. Micro Center (Apple service) did the work. I told them (a tech there) that I was thinking of placing a larger Samsung 850 Pro 1TB drive in it.. when I asked of TRIM for that drive. He stated that for the past 2 years of working with the Samsun drives, "we don't enable TRIM. The drives controller handles that".
