[How To] Enable TRIM On Your Mac SSD to Prolong the Life Span
Solid state drives are amazing drive replacements for hard disk drives. They have awesome read and write speeds, they are durable, and they use less energy. The large misconception is that they last forever. Just like a hard disk drive, a solid state drive is susceptible to degrading with use. They must be maintained just like a hard disk drive must be. In the last couple of years, our understanding of how the solid state drive works has advanced so quickly that we are now ordering them standard in many computers that we own.
One thing that you might not have known, is that you can increase the life span on your solid state drive by enabling a tool called TRIM. It's not an acronym, it's a command. TRIM is used to help clean up your solid state drive and keep it alive longer. The way that a solid state drive works puts stress on certain memory blocks. Imagine that you have just written data to a clean solid state drive. If you delete part of that data, the solid state drive will simply do what a hard disk drive does and tell itself that it can rewrite over that part. In other words, the deleted data stays there waiting to be over-written. Now, when the solid state drive goes to rewrite over that part that you deleted, it will have to erase and rewrite the whole amount of data that you wrote. Not just the part that you deleted. This is why performance is reduced and why solid state drives can slow down or die over time. This problem can lead to fragmentation due to NAND memory getting clogged with both deleted and stored data.
TRIM is a tool that helps erase that deleted data from a solid state drive when you delete it. It helps ensure that the solid state drive doesn't have to rewrite the whole amount of data where you deleted just a part of it and that the solid state drive can simply rewrite over the part that you deleted. TRIM keeps your NAND memory looking as clean as when you bought it so that the memory is ready to be rewritten to again in the future.
Mac computers come with TRIM automatically enabled on Apple-shipped solid state drives. But, if you bought your own solid state drive and you install it yourself, then TRIM will not be enabled. This can be dangerous. Life spans of non-TRIM solid state drives can be dramatically lower than TRIM solid state drives. If you bought a solid state drive yourself and installed it on your Mac, then you should enable TRIM. To do this, you can download a tool that will patch your solid state drive so that the Mac recognizes it as one of Apple's. It was recently updated: TRIM Enabler 2.0 beta 4.
As you see from the screenshot above, enabling TRIM is as easy as turning on a switch. Once you have it turned on, it gets to work making sure that your solid state drive isn't coagulating with deleted data. This is an extremely important tool for Mac users who have installed a solid state drive and I cannot stress this enough. You need TRIM. Do you have TRIM already? Share in the comments.

Installed and Activated. Showed that my HDD also had SMART on.
But it does not show Lifetime Writes, so how does this Trim Really help me O.o beside Cleaning up.
I was told KINGSTON SVP100S296G Had a build in trim alike system on the SSD ???
How different is this over the one on SSD ?
Medium Type: Solid State
TRIM Support: Yes
Partition Map Type: GPT (GUID Partition Table)
S.M.A.R.T. status: Verified

DO NOT FOLLOW THIS ADVICE.
This is extremely irresponsible and wrong information to be writing on this site. You NEVER use third party software to "trick" an SSD into using TRIM. DO NOT DO THIS. Instead of giving this horribly irresponsible advice, you should tell your readers to consult the manufacturer of the SSD controller or the manufacturer of the drive itself on whether or not you should use this third party software. I have an OWC drive and they explicitly state that you do not need to use any software to enable TRIM because their controller has really good garbage collection algorithms already, and as such they do not support using this or any other tool. I cannot believe that you wrote such a terrible article and gave such terrible advice. NEVER "fool" any kind of data drive into doing ANYTHING without the manufacturers blessing. That's a sure fire way to lose data and void a warranty. I suggest this article either be severely amended to add factual information and sufficient warnings, or be deleted altogether.
DO NOT FOLLOW THE ADVICE IN THIS ARTICLE. IT IS IRRESPONSIBLE, WRONG, AND COULD VOID A WARRANTY OR DAMAGE YOUR DRIVE.

do I need to open the application every time I restart of just once to active trim?

SSD's are incredibly different from chipset to chipset, stop thinking like it's one size fits all.

"If you bought a solid state drive yourself and installed it on your Mac, then you should enable TRIM."
"But, if you bought your own solid state drive and you install it yourself, then TRIM will not be enabled. This can be dangerous."
"This is an extremely important tool for Mac users who have installed a solid state drive and I cannot stress this enough. You need TRIM."
All of those statements are completely false. You DO NOT NEED TRIM on almost every drive made in the last 18-24 months. It's simply untrue to say that if you bought an SSD yourself, that you need TRIM, it's dangerous not to have it enabled through some software a dude wrote and put on the internet, or it will fail spectacularly within a few months. There isn't a non-TRIM enabled SSD or one without good Garbage Collection anywhere in the market. You simply cannot get an SSD that doesn't have either one or both of those things. Adding this into OS X to force TRIM on your drive is a good way to void a warranty and the author says absolutely nothing about this. Go ahead and contact Oskar Groth when your drive dies and see if he'll honor your warranty. I guarantee you that if your drive fails and the vendor finds out you used third party software from some dude that lives in Sweden to force the drive into doing something, they will void your warranty and tell you to go pound sand.
If you want to follow this advice, go right ahead. I just hope that the writers irresponsibility and your ignorance help you pay for a new drive when the manufacturer voids your warranty for using some software you found on the internet. My advice is to take 15 minutes and contact/call the people who made your drive and find out what they recommend and what they support. Reading some blog post by an ignorant writer, on a website that has had a long history of hiring more ignorant and irrelevant writers, and blindly following the advice built on fear mongering is a really dumb thing to do. Especially with a component that isn't cheap and isn't readily available in large quantities. Go right ahead though, enable this software. What could go wrong right?

On a side note, I just built my Win7 box on an SSD and did some back to back tests and the performance increase is VERY noticeable. Highly recommend people look at ssd's as their next hardware purchase.

The next article is on USB stick drives. I bet the arguments in that will be a blood bath. Lol
I turned TRIM on and my microwave dinged. Coincidence? I think not
Sorry, I had to toss that in there. I am old school, I still use 8" floppy disks

This is kind of funny. I stopped reading this site regularly a few months ago because the numerous blatant technical errors and inaccuracies that plagued Anthony Bouchard's articles made it so frustrating to read.

Might I suggest you read my other comments on this story. If you can muster some sort of reading comprehension from somewhere you'll see why this article is FULL of incorrect and dangerous assumptions about SSDs and the advice given is horrible. There are multiple statements that are completely and utterly wrong. Maybe if you read more than the first few sentences and the headline you'd know this. But obviously you didn't and decided to call me out as a troll while being one yourself.
The problem with this article is that it passes off opinion as fact. What's written here isn't even based off fact, it's based off interpretation and gives no reliable or complete information to support the opinion stated. This article is wrong almost all the way through and the advice and information should be ignored and not trusted respectively.

[QUOTE=KartRacer;6366974]According to OWC, it can in fact damage your drive. But I'll be sure and listen to you and the writer because you obviously know more about their hardware than they do.
Actually, no. You do not use third party drivers to enable TRIM. Unless you have the blessing of the manufacturer or like to use unverified software off the internet without a sliver of a chance of getting support from the dude who wrote it. Which you won't get any and it's extremely irresponsible to recommend using this without any disclaimer or warning. The writer DOES NOT explain any of this in the article.

This piece sounds like it was written by a 10-th grader, with an equal knowledge of computers and the subject. There is absolutely nothing in this column that leaves you more informed after you read it. You guys need to find someone who knows what they're writing about and spend more money on hiring them.
