TRIM Support Enabler

Hello,

A few questions before I try to enable trim.

1. how do I know if my SSD's have garbage collection on them?

2. is it OK to run trim and Garbage Collection at the same time?

3. on OSX 10.6.8 can I get trim to run on 2 SSD?


Thanks!

Yes. Both of those have firmware that performs garbage collection.

I am not aware of any SSD currently sold that does not perform garbage collection of some sort in firmware.

Yes you are correct, even old intel ssd has garbage collection but it might be slow and not so effective.

Yes... or it could work like it is designed to. If the garbage collection in these newer drives did not work well one would think the forums would be full of users saying their SSD write speed has slowed since they bought it and we don't see forum posts like that.

I think it depends how often you write/delete on the SSD. For normal use it should work. Anyway for the Mac SDD I enabled it myself using the guide:

http://digitaldj.net/2011/07/21/trim-enabler-for-lion/

So you know what you are doing. It easy and clean and you can restore it back to the original setting easily.
 
Just wondering here, i have installed the Trim Enabler and after a restart it appears to working fine but when i try to boot into x64 then it says that trim patch is applied but either the sdd doesnt support TRIM or i need a restart. So basically each time I shut down, hold the 6 and 4 key to boot, Trim Enabler doesnt work, but it works fine for a regular boot. Is this normal or am I doing something wrong.
Thanks
 
Hi everyone,

I just bought a Crucial M4 256GB for my MBP mid-2010 running on Snow Leopard 10.6.8. Will I need to use TRIM Enabler?
By the way, I can't download it from groths.org, links seem broken :(

Thanks!

Just for clarification, if the ssd has garabage collection you do not need this enabler correct?

What would happen if you do install it and your ssd already has it? Any side effects etc to doing this?

No - not correct at all. TRIM would be fine additionally.

BUT

Nevertheless I wouldn´t do that as long as no loss of performance exists,
as there seem to be to many problems around with the enabler so far.
 
fsck a non-boot drive

My MBP has two SSDs. I patched the system and booted into save mode to run fsck. The fsck output only shows it did something to my boot SSD. It's not doing anything for my other SSD. Looks this version of fsck has no input to specify a different filesystem. Any one knows how to trim the non boot drive?

running fsck_hfs instead of fsck did the trick. fsck_hfs accepts the target file system by parameter, which in my case was /dev/rdisk1s2.

Mmmm... which kind of issues are you talking about?
 
Hi guys,

I have a MBP 2011 and I replaced the hdd with a Vertex 2 from OCZ.
I tried to patch my Lion with Trim Enabler but I had no luck.

Question: Do I really need to patch the OS as long as I know that this SSD has a good garbage collector?

Thanks.

As the app says, you need to reboot after patching.

If you still dont get Trim Enabled after reboot, it is possible your SSD needs a Firmware Update to support Trim.

Reading through this thread might give you the answer. It's been discussed like crazy. I'd say there are as many people against it as there are people saying it's good. I'm no pro on the area so I will not comment it anymore then saying, try it out, if you notice any problems, it's so easy to disable.

Thank you for taking some time to reply :)
I did rebooted for sure but the application still notify me that I need to reboot. I also know that the OCZ Vertex 2 has trim support.
Now, regarding the "garbage collector suport" I was just asking for an opinion as log as I can not find a conclusive answer :)

Thanks for the answer anyway, I'll look search some more regarding this topic.

P.S.: This is my first Mac and the first time I'm interacting with MacOS more than 10 minutes :). I have a very good linux background though :)
