Mac OS X 10.10.4 Supports TRIM for Third-Party SSD Hard Drives

TRIM is not an internal function of the SSD, they have "Garbage Collection" schemes already enabled in their firmware. Trim is an Operating System function which communicates deleted storage locations to the SSD. This OS X functionality is disabled for non-Apple suppled SSDs in Mac computers. It is possible to enable this functionality in OS X for your SSD, and the method for doing so varies with what version of your OS X you are running.
There are several threads on this Forum (including this one) which will explain this in much more detail, including the best ways to enable it. You may want to read through some of these posts.

It´s a Toshiba Q Series Pro.
Performs very well, went from a 50 second boot time on the stock HDD to a 10 second boot time..
Interesting... I wonder if they are using the same trick as Angelbird SSDs to fool the OS into thinking it is an Apple OEM drive.
I didn't know about angelbird, they proved its possible, maybe Toshiba did the same.
I find "new" manufacturers always interesting. Why did you choose Toshiba? Are they known for their performance and reliability? I know Apple uses Toshiba SSDs, but only if no other options are available.
I also heard apple used Toshiba SSD´s, that was the reason for choosing it, but a few days after using it, issues started to develop, beach balling, app crashes, tried with and without TRIM, but no change, so i exchanged it for a Samsung 850 evo, with TRIM on from day one, so far so good, (knock on wood) The Toshiba seemed to be a very good performer, but was´t reliable on a Mac. The Samsung is no less a performer.
just turned on TRIM via apple's terminal command on my SSD, macOS 10.11.5 (no typo) installed;
KINGSTON SV300S37A480G:
Capacity: 480.1 GB (480,103,981,056 bytes)
Model: KINGSTON SV300S37A480G
Revision: 603ABBF0
zoom. zoom indeed.....
Strange, it stayed enabled on the MacBook Air I upgraded; this Air has an aftermarket SSD which doesn't natively get trim support.
Where might one find the Trim Enabler 3.3 to work on Mid-2012 MBP with Samsung 850 Pro SSD Installed?
Is there a Link? Is there a cost?
Thank you.

- The whole point of this article is that such utilities are no longer needed. There are instructions in the article itself.
Updated to Sierra on the day, and didn't realize that during install, trim is disabled by default. Just noticed the word "No" beside trim support in system report last week. I usually check through all settings during updates but never thought of this one. Now noted and will be checking in the future.

Mine wasn't disabled with the upgrade to Sierra, so there doesn't seem to be much consistency here.Updated to Sierra on the day, and didn't realize that during install, trim is disabled by default.

For me it appears that it is disabled for a few minutes and then re-enables itself permanently. That was what I noticed with my Mac Pro. I will update another machine next weekend, and will take good note and report back.
Dang, I just checked & right enough says No in System Profiler, upgraded to Sierra the day it came out, WTF?
Strange thing is the crucial still says yes, the sam 850 pro says no, not that I've any idea why?
