Did the erase and re-do of commands via re-doing the patch on my intel 160 GB SSD in my 09 MacBook Pro 2.53 / 8GB ram and everything is great, gained 1.25 GB of free space and xbench went from 235 to 284, boot time is now 16 seconds.
The drive has 40GB of free space, has been in use since Feb of 2010.
Nothing lagging, all good.

I'm aware they're from another manufacturer, but I'm not able to find out which model they are rebranded from.
Apple could potentially have customizations in the SSD, and trying to flash it with an OEM FW update might potentially brick it.
Quick question for all of you with Trim enabled SSD's. When you delete files, are they still going to the trashcan or are they immediately deleted for good? I just installed a Micron c400 SSD and enabled Trim w/o testing deleting files before finishing the install. It seems like all my files are removed instantly w/o going to the trashcan. Not sure if this behavior is consistent w/ SSD's on OS X in general or only ones with Trim enabled.
Any help to revert this behavior or insight to why this is would be greatly appreciated!
Thanks.

Hi I have a Micron C300-MTFDDAC128MAG with the Trim activated and the deleted files go into the trash and can be reverted "Command Z"
And thanks goes out to Oskar for all the hard work.

Hi everyone, I am not as computer savvy as most of you here - but a few days ago I ran disk utility on my macbook air (SSD) to erase free space and then my computer became extremely slow with shut down and restart. I noticed that my computer did not have trim support.
So today I did the terminal commands:
sudo chown root:admin /
sudo kextcache -system-prelinked-kernel
sudo kextcache -system-caches
My computer is now faster. Was this okay to do without enabling my trim support? And to confirm with the next software updated for 10.6.8 it will automatically enable the trim support??
If I want to securely erase in the future - should i go through disk utility again?
Sorry for stupid questions

Hi everybody,
I 've got a MBA 2010 and wanted to patch with trim enabler.
After that booting went slow, so I wanted to use the 4 terminal cmmands, but it asks me a sudo password that I dont know.
do you have an idea hot to use these 4 terminal commands to get it quickly as before.
thanks

How come it took Apple so long to implement TRIM!! My 1.5 year old X25-M feels like I just installed it on my 2006 MB! Thanks OP for putting the easy to use utility together and for post about fixing the post erase free space terminal commands. Welcome back sub-20 second startup times. Yay!

No wonder, since the actual deleting (and subsequent TRIMming of the free space) takes place first when the trash is emptied.
It depends if Apple adds newer disk driver in 10.6.8, then it overwrites the patch.
You should be fine patching again in 10.6.8 though, especially since people have reported the patch even works in Lion with no troubles.
I thought he was asking if 10.6.8 would add TRIM on its own (without your patch). But as I reread, his question can be read either way.
I installed TRIM yesterday on my Mac Pro 1,1 with an 80GB Intel SSD (X-25M G2). This is not a bootdrive but an applicationdrive (games and VMs).
I also upgraded the firmware on the SSD to the last available version and that made a HUGE change when it comes to Uncached random writes. See below (I had similar uncached random writes results in Xbench after FW upg. I have not included that bench in this post)..
As usually Xbench results can differ a few % up and down between runs.
After TRIM and Erase, WoW starts (From play on launcher to login) in below 4 sec and this was usually 6-7 secs earlier and I could copy one of my VMs to the SSD that couldn't fit earlier.

This is a VERY useful feature and I'm surprised that Apple hasn't pushed it out yet. I installed the patch last week, and then forced a TRIM yesterday by erasing the free space. That pushed the restart time up to about 30 seconds. After reinstalling the patch, my restart times are now back down to 12 seconds, which is about a second better than what I was getting when I first got the system (it's a refurbished 11" MacBook Air 1.6GHz).
So every time you run TRIM, you have to enter those commands in terminal?
How often should you TRIM the SSD? I know that's a very relative question, but I'm sure there's an average answer.

You doesn't. The software which has been put together by Cindori makes the OS X to operate properly with SSDs that do it automatically. TRIM is to be enabled, not executed by the user. The SSD does it by itself.
I asked in another thread and they said it wasn't in the 2nd Dev Preview. That doesn't mean Apple won't add it in a future build.
