For anyone interested installing a ssd in their Mac, i put a 256 gb Samsung 850 Pro in my 2011 Mac Mini.

I installed it 8/17/14

No trim enabled.

Performance has not degraded in the slightest.

I get the same write on my Crucial MX100 512 installed a few weeks back. However, I only get 499 read. 2011 mini server.

We shall see if the speeds maintain like yours.

I have installed SSDs in my Macs since 2009, never had trim installed - only the original Intel drive ever showed signs of slowing.

Video pros might say different, but for the average user, just set and forget/enjoy.
 
I agree with the OP's experience regarding TRIM.

I've had similar experience, booting and running a late-2012 Mini using a Crucial m500 drive mounted in a plugable.com "lay-flat" USB3 docking station (with UASP). No perceivable slowdown in performance after nearly a year of operation, and only the slightest degradation when measured with a benchmarking utility like BlackMagic.

In spite of all the hubub and tweaks, TRIM seems all-but-unecessary on the Mac, and entirely over-rated.

I sense that many SSD drives now on the market don't even need (or utilize) it.

TRIM is becoming a "dead issue", of little importance.

My opinion only, others will disagree, some will disagree vehemently...
 
I have a 2011 mac mini server and recently installed a Crucial MX100 512gb with read and write speeds around 500MB/s. No trim enabled either. Works greats and would recommend!

[[ The only thing i did was over-provision the ssd by 9% ]]

This begs the question:
How did you do this?

If you care to reply, could you describe the steps you took?
 
On a newly installed ssd do a fresh install of Yosemite. Once installed open disk utilities and under partition just shrink the ssd by 9% on a 256GB that's about 25GB reduction.
 
Anand recommended 20-25% back in the day. (Sorry lost link)

Anandtech has often written on this topic. The following is probably the most comprehensive article, although it is over two years old.

Anandtech's final thought in this article is:

"For drives on the market today that don't already prioritize consistent IO, it is possible to deliver significant improvements in IO consistency through an increase in spare area. OCZ's Vector and Samsung's SSD 840 Pro both deliver much better IO consistency if you simply set aside 25% of the total NAND capacity as spare area. Consumer SSD prices are finally low enough where we're no longer forced to buy the minimum capacity for our needs. Whatever drive you end up buying, plan on using only about 75% of its capacity if you want a good balance between performance consistency and capacity."

Thank you; that'd be what I remember reading. :D
