Anyway, if anyone knows the "new" trim command, it would be greatly appreciated.
Good afternoon,
I can confirm that TRIM can no longer be natively enabled in either Mavericks or Yosemite through the old Terminal commands. I would sincerely recommend against using TRIM Enabler as people who have used it have had issues with the OS not booting after an update.
In all honesty the life of an SSD will likely exceed that of the machine's. Without TRIM it's not going to do a whole lot of damage. The only way to now enable TRIM is to purchase a TRIM-enabled SSD in the firmware - there is a third-party company who provide them, but I can't remember who it is.
In my opinion the benefits of having TRIM enabled on OS X are not worth the potential problems that are caused by using TRIM Enabler. I've been using non-TRIM enabled SSDs on OS X for some time, in addition to upgrading them on a number of Macs through my work. I haven't had any tech issues for the last year on non-TRIM enabled SSDs.
I hope this provides some reassurance.
Trim Enabler has no problems on Mavericks....it's Yosemite that may cause issues on restarts after s/w upgrades.
I wasn't talking about TRIM Enabler, I was talking about enabling TRIM using the Terminal commands. It doesn't work in either Mavericks or Yosemite.
if you dont know what you're doing, you can easily mess up your system.
so stay away from the terminal and better use trim enabler.
Or even better, don't enable TRIM at all. It's not going to do it any harm if TRIM isn't enabled.
thats what i'd like to know… is it so? who says that?
until now i didnt find a solid source about the disadvantages when trim is disabled.
Well general reliability of SSDs will almost always exceed the life of the system. TRIM being enabled is basically just garbage collection and prevents future writes to blocks that are already in use. However with almost all modern SSDs, the firmware has some level of this anyway. Furthermore on Sandforce SSDs, enabling TRIM will actually do damage rather than benefiting it.
Let's consider the worst-case scenario without TRIM being enabled. Let's say that due to it not being enabled, things are being written over, and over, and over, to the same blocks, rather than other ones. Well, modern SSDs are so incredibly reliable that the lifespan will exceed that of the system, even under stresses that no consumer/professional would get anywhere close to. See following article: http://techreport.com/review/27062/the-ssd-endurance-experiment-only-two-remain-after-1-5pb
So are there slight benefits in enabling TRIM? Technically, yes -- but with the reliability of modern SSDs and the built-in firmware doing most of the garbage collecting anyway, it's not going to be a difference that you notice.
However if you enable TRIM in OS X for a non-Apple SSD, there is a chance that it will be bricked in a future OS update. It's happened before, and it'll happen again.
So for those reasons, that's why I always recommend against enabling TRIM. On Mountain Lion/earlier you used to be able to enable it through Terminal commands. Now that you can't, there's an awful lot of danger in using TRIM Enabler to write over OS KEXT files ... I mean, come on guys, who in their right mind would think that's a good idea. The benefits of enabling TRIM with a 3rd-party tool definitely are not worth the potential problems IMHO.
sigh, again..
the trim enabler modifies the driver/kext file
the terminal command modifies the driver/kext file
same thing!
Interestingly, nobody mentioned the *speed improvement* when enabling trim? People keep mentioning the "life" of an SSD. I say 'who cares' about the SSD life?!?

I'm not sure why it matters. TRIM was enabled. Mission accomplished.
