Apple's MacBook Pros ship with active SSD TRIM support in Snow Leopard

New MacBook Pro models are shipping with Mac OS X 10.6.6 (build 10J3210), which supplies TRIM support for bundled Apple Solid State Drives, enabling extended performance of the fast new devices via background maintenance.



AppleInsider previously reported that Mac OS X 10.7 Lion would incorporate support for the TRIM command, which helps the operating system coordinate the maintenance of unused memory cells on the new SSD devices, preserving long term performance.



However, we can now exclusively report that Apple has also added the feature to the revised build on the latest, Thunderbolt-equipped MacBook Pros that shipped earlier this week.



While they appear to run the same Mac OS X Snow Leopard 10.6.6 version, the newer build (10J3210 versus 10J567, the newest build of Mac OS X 10.6.6 available for download from Software Update by other Macs) includes and automatically activates TRIM Support, as noted in System Profiler.









Apple will likely roll out support for the new feature in an upcoming new build of Snow Leopard. The feature reportedly only supports Apple-bundled SSD volumes, but this may change as well.

    It might just be saying the drive supports the TRIM command, not necessarily that it is being used...

    I would hope I don't have to pay the Apple tax to get this feature as I just got an OCZ Vertex 2 drive.

    Worse, I have an Apple SSD equipped 2009-era 13" MBP and am running the OSX Lion Beta on it, and no TRIM support mentioned. What gives?

    I don't suppose someone could explain to me what TRIM is?



    Thanks.

    Maybe they're mad that you're violating your NDA or using software that doesn't belong to you.

    Drives that support TRIM (all SSDs) already show up in Snow Leopard as "TRIM Support: No," so this this something new.

    I suppose you could click on the link in the article and read about it. Or perhaps use Google or Wikipedia if you don't trust AI.

    Did you pay the OCZ Vertex 2 tax? If so, ask them what services they provide. Maybe they expect you to wrap their device in a Windows PC. Of course, the Windows PC tax is significantly higher than the cost of Mac OS X.

    Or I could ask some of the nicer people here, and hope not to just get snide remarks like yours.



    Some people here are helpful. Others not so.

    Are you sure your drive supports trim?

    I'm not sure if there is a difference, but according to some testing by MacWorld MBAs equipped with SSDs don't necessarily have the performance issues with writing that TRIM supported drives avoid:

    So you might have nothing to worry about if you have a made to order MBP.

    Yes, no problem. GOOGLE.

    I just put an Intel 510 series 250GB SSD in a Late 2008 MBP and despite the drive itself supporting TRIM, 10.6.6 does not. Hoping that 10.6.7 will enable it.



    BTW, Intel 510 SSD works fine in a Late 2008 MBP as stated, but does NOT work in a Mid 2010 MBP. You can clone an old SL drive, but you can't install SL from scratch. I tried everything and no go!

    Seems to be ok with the Nvidia chipset of the 2008 and not the intel chipset of the 2010.

    Ironic!

    I've been told by some that if you are using whole disk encryption (PGP etc) then TRIM doesn't do you any good. The entire drive always seems to be full, since the entire drive is always encrypted. This means that TRIM never see's "unused space" to clear out. Haven't tested it myself, since I can't justify the expense of an SSD.

    That's definitely the dumbest thing I've ever read on this site. Maybe even the internet. Wow. I sincerely hope you forgot the sarcasm tag.



    Pretty sure you won't have to buy an Apple provided SSD to have TRIM. It would be powerfully stupid for Apple to make that move. I just don't see it happening.
