Trim or Not to Trim with 3rd Party SSD

Trim or Not to Trim with 3rd Party SSD in OSX, Windows 7, etc.

I read up a little and seems that for OSX enabling trim support might be a bad idea with 3rd party SSDs. In my case I just bought a a Vertex 4 for my Macbook Pro running ML 10.8.2.

Was about to enable trim support when I read including in OCZ manufacturer forums that enabling trim is not recommended and may interfere with the drives own firmware clean up of free space, etc.

Wondering what the opinion here is and whether that opinion is different for other OS.

Also if this ? is in the wrong place please let me know.

Welcome to the forum.
TRIM on Windows 7 and 8 works very well on SSDs, including the Vertex 4.
I’m afraid I can’t advise on Apple OCX, but knowing Apple, it wouldn’t surprise me if they done something to screw up TRIM with 3rd party SSDs.

Maybe some Apple users here can provide better info.

This is nonsense anthlover unless the SSD has broken/buggy firmware in which case IMO best stay away from it. Would you post a link where this was stated?

Dear Sir,

as you know, TRIM isn’t available for the Vertex 4 under OS X due to Apple policies. We don’t recommend using the TRIM Enabler, as it can cause issues. The Garbage-Collection Feature will help the drive to remain it’s performance after usage.

Hello,

that’s correct, the Garbage-Collection feature is active in IDLE-State. The rest will be handled by the Operating System, so no need to change any other settings. Disabling Backup Settings/Features should be sufficient in order to avoid write access.
