El Capitan and non Apple SSD drives using TRIM

Non-Apple TRIM Enabler is no longer needed. Apple has relented and put in a way to enable TRIM on Third-party drives. It is subject to manual enabling, and when you do, you agree to the massive disclaimer shown in this article:

http://9to5mac.com/2015/06/12/os-x-ssd-trim-support-el-capitan/

.

Sorry If I missed something, but I would like to ask whether I can safely enable TRIM on my new SSD drive. I have upgraded my MBP Late 2011 with new Samsung EVO 850 drive, and did not find any clear confirmation that it is safe/recommended to enable it under El Capitan.

I understand the benefits of TRIM and I am definitely for using it, but there is the "Crucial" thing (that it should not be enabled on some Crucial drives - and this is NOT my case since I have Samsung), and also there is this massive Warning disclaimer.

So, is anyone there with working, real-life example of using Samsung drive while having TRIM enabled, under El Capitan?

Of course, everyone will tell me "you have been warned", but I also understand that Apple must warn users in these disclaimers...

Thanks for help!

Actually it seems that the pundits of TRIM are getting less and less as

drive manufacturers get improved controllers with better and more efficient

garbage collection, wear leveling, etc.

TRIM was actually available on the very last Yosemite release and I had tried

it for a while on my Macbook Pro and really saw no change, actual or perceived.

The drive was a Kingston SSDNow v300 which Kingston was claiming also that

they really didn't need it.

and really saw no change, actual or perceived.

TRIM will generally NOT cause a contemporaneous performance increase, and that is as expected. The use of TRIM on an ongoing or occasional scrubbing basis reduces the likelihood that you will get into a diabolical near-race condition.

This condition is where the drive shows LOTS of free space under Mac OS X, but that free space is fragmented. The drive does not have enough empty Superblocks available for Fast Writes. This can cause performance to degrade very suddenly and quite substantially, and can cause the drive to stop working entirely. Although this condition is rare, it is extremely ugly to have it happen.

--------

Pundits are getting less vociferous because TRIM has become generally available, not because its need has been reduced or eliminated.

Yes, that is the reason why I wonder If I can safely enable it. I don't expect any performance gain, all I need for the drive is its longevity and safety. My previous original 120 GB SSD from Apple (Toshiba) had about 5 - 10 GB of free space in the last 2 years, and I was really struggling keeping that space available.

When I cloned the drive to the new one, I discovered that only about 90 GB of data was transferred, and while some space was occupied by the Recovery partition, I considered the missing space was destroyed/wasted by the dying SSD cells (as this tiny remaining space was constantly being overwritten).

Now I have 100 GB of free space, but I want to give the drive the best treatment, so should I go for TRIM, any vote up or recommendation? Thanks guys!

Don't you love when you come to a forum for a straight answer and everyone chimes in giving you useless info and their opinions?

Short answer: YES - you can (and should) enable built in trim now

in terminal type:

sudo trimforce enable

(then enter password)

It will prompt you for a reboot, so make sure you're not doing anything important at the time you try this. Also, remove any third party trim enabler patch too!

I have an MBP Mid 2009, running Maverick on TRIM enabled SSD. Can I safely update to El Capitan? Or is the any procedure I have to follow to update it safely to El Capitan?

Thanks

1. With any change that may re-write over 350,000 files, it would be a big mistake to proceed without a Trusted Backup.

2. The upgrade is intended to not modify anything outside the System area, and to quit with your original System intact in case of early problems. But stuff happens -- see #1 above.

Update: I have successfully enabled TRIM under El Capitan with my Samsung EVO 850 drive, and so far everything seems OK (after 2 days of use). I have a good feeling from that.

Durandall is your SSD still running fine? I put an 850 EVO in a late 2011 15" MacBook Pro. Just wondering how it's working for you.

Thank you!!

Yes, my EVO 850 still runs fine, without any issues, with TRIM enabled. It seems that this is final solution, so the worries were false.

Which EVO 850 are you using? What GB size? Any problem yet? I'm building a reference blog for TRIM support on third party drives and your information would be helpful to others, including me. Im searching for a compatible drive for OS X 10.11
