Should I enable trim support on Crucial M4 512?

I've got a Macbook Pro 10.8.2 , mid 2010 , with a Crucial M4 512 SSD installed.
Is there a benefit in trying to enable trim support?
Thanks, Jon

I also wasn't impressed. Sometimes hangs etc.
I enabled trim and now everything seems faster. May be the reboot.
I tested performance before and that seemed good for copying a file or so, but not for lot's a file access.
I ran in 1 terminal : iostat -d 1
in another : mkfile 1g empty
cp empty empty2
that looked great.
anyways, happy with trim now.

  • Should I enable TRIM for Windows 7 Ultimate 64 for my MacBook Air?

    Can I enable TRIM support in Windows 7 for my MacBook Air?

    When you installed windows 7, TRIM would have already been enabled if the SSD supports it. Windows 7 auto detects SSD’s
    To check TRIM is on at command prompt type
    fsutil behavior query DisableDeleteNotify
    the result will be 0 if it’s enabled

  • If I get one of the Toshiba SSDs and put it in my 2011 MBP, will it auto enable trim support?

    If I get one of the Toshiba SSDs and put it in my 2011 MBP, will it auto enable trim support?

    It is outrageous that Appe deliberately does not enable TRIM support native to the OS to non Apple SSD drives automatically. Even worse is to cancel it after an update of the OS.
    It is forcing anyone who does not add up to your greedy aftersales target to eventually experience trouble with their non Apple drives.
    It is monopoly, isn't it?
    It does also sounds petty, very disgusting from such a reputable company.
    I love Apple but they do not need to go down such length to whatever are their aims.
    Very disappointed to find out that the TRIM support I enabled prior to the update 10.9.3 is now disable.
    Simply unbelievable!

  • Enabling TRIM on MBP 2010 ?

    Hello,
    Few weeks ago i installed Corsair Force GT Sata 3 SSD.After a while i was curious about if im using on full performance.Then i found out TRIM Support is not enabled. Some sites says do this do that on terminal to enable trim support but i was wondering can anyone help about this ?
    Macbook Pro 2010. Core i7 (non sandy bridge) 4GB Ram.Mac OS X Lion.
    Corsair Force GT Sata 3 120GB 555mb/s

    I don't have engineering data. But let me give you this. All SSDs sold by Apple and installed into Apple computers have TRIM enabled Automatically by the OS.
    All SSDs installed into any PC running Windows 7 TRIM is enable Automatically. It is only with Mac OS X and NON Apple SSDs that TRIM is NOT Automatically enabled.
    So what does that tell us. Apple feels so strongly that TRIM should be enabled on Apple SSDs that they do it Automatically. Microsoft feels so strongly that TRIM should be enabled on ALL SSDs that they do it Automatically when using Windows 7.
    The only place I have ever read that TRIM support is not needed is on the OWC website promoting their RE-Branded SSDs. You will not find that same info on any website of a major manufacturer of SSDs.
    Now Apple does not have one brand of SSDs. Just like the spinning HDD they use they buy the brand/model that fits there price point at any given time they are in the market for more components of that type.
    So with all that stated it is my honest and well informed opinion that whenever you are using an SSD you should always enable TRIM support.
    I hope that is now clear to you.
    You may think differently. That is fine.
    But I don't care for your tone.
    Thanks.

  • Trim support in mountain lion for third party ssd

    Hi,
    I have an Intel 320 series SSD in my intel core duo 2008 2.6ghz macbook pro.
    I had trim support enabled in Lion and tried to re-enable it with the usual terminal commands after upgrading to ML.
    The first two commands to back up and patch the new file appear to work, but when I try to clear the 1st cache using:
    sudo kextcache -system-prelinked-kernel
    I get the following error:
    Kernel file /mach_kernel does not contain requested arch: i386
    Then in system information after reboot it says that trim has not enabled.
    Does anyone know how I can re-enable trim support.
    Many thanks,
    Simon

    I tried this and it wouldn't work for me. It backed up the file, but when I tried to open the .kext file with the same editor he used, it wouldn't allow me to open it. I also tried logging in as the root user and didn't work either. Any ideas?

    Technically, TRIM is not supported by Lion for non-Apple-branded SSDs, but there is a work around for this.

  • Enable TRIM on SSD Mac OS X Mountain Lion

    I recently purchased and installed a Samsung SSD 840 Pro series on my MacBook Pro. I was reading up on SSDs and I heard something about enabling TRIM and how it makes the SSD last longer. How can I enable TRIM on my SSD on my MacBook Pro that's running Mac OS X Mountain Lion?

    TRIM is necessary as SSD have limited writes, so the new written data has to go to a  less frequently used spot on the SSD.
    It's a real shame Apple doesn't automatically enable TRIM on non-Apple SSD's, it knows when it formats it that it's one as it won't enable scrubbing.

  • Apple SSD SM128 Trim support?

    I have an older MacBook Air (2009 I believe) that has an Apple SSD SM128.
    I'm told the latest version of Mac OS X version 10.6.8 enables TRIM support for all Apple SSD's.
    I installed 10.6.8, but my system still reads "TRIM support no" when I check the System Profiler.
    Does anyone know how I can get TRIM support for my SSD.
    Thanks,
    Sean

    MacRumors reported Apple add TRIM support for Apple SSD's in 10.6.8.  Am I reading something wrong?

  • Enable TRIM for Solid State Drives

    Does Lion enable TRIM support for solid state drives?  If it does how do I enable it?
    I already know that my drive supports TRIM.

    Only for Apple SSDs. This utility, TRIM Enabler 1.2, is supposed to enable it for third-party drives. Note that the newer SSDs may not need TRIM.

  • TRIM Support Enabler Patch

    Hi Community,
    I read a lot of posts the last view days which explained that the TRIM support will only work with Apple SSDs, but there are many patches available which should enable the TRIM support for those third party SSDs as well. Are those patches only fakes or are they functional? Has anyone confirmed if those patches doing there job as expected?
    Thx & Bye Tom

  • Trim support not enabled

    I got this MBA with SSD(251GB) a couple of weeks ago.  I noticed that the "No" is shown for the Trime support. Does this mean that Apple SSD does not support Trim? Or, can that Trim support be enabled?

    With the 10.6.8 update apple has added in TRIM support for stock apple oem ssd drives. 3rd party ssd drives are still s.o.l for Trim support at this time even in LION unless you use the "trim enabler" hack.
    I do not advise doing so, as it has messed with a few systems, and basically could just be code that switches the "no" to a "Yes" in profiler without any actual background use.

  • TRIM support available in Mac OS X 10.6.8 update?

    Several Apple fansites are reporting that the recently released Mac OS X 10.6.8 update adds TRIM support for non-third party SSDs, with screenshots as proof. Since I own a MacBook Pro with SSD built in, I was quite excited about this. However, after installing the update and restarting, System Profiler still says TRIM support is not available... My questions to the Community:
    * Did anyone else have this experience? Do you have TRIM support enabled after installing 10.6.8 or not?
    * Did I miss a step somewhere? Should I enable some setting manually?
    Thanks in advance. Cheers!

    Hi,
    same same.
    SSD native on a mbp Q4 2009.
    I was excited to activate TRIM functionality with the 10.6.8 upgrade...no way...
    I heard we still have hope with the final release 10.7
    Apple, you should take care of geeks like us experiencing with SSD before all the others.
    We expect you to fix the TRIM function....
    Thanks,

  • [solved] enable trim on ssd

    this link from the wiki says i should edit my /etc/fstab in order to enable trim on my ssd.
    this is my /etc/fstab
    # /etc/fstab: static file system information
    # <file system> <dir> <type> <options> <dump> <pass>
    # UUID=6b44daaa-610c-4f23-a632-569d091e4d43
    /dev/sda1 / ext4 rw,relatime,data=ordered 0 1
    should i replace 'rw,relatime,data=ordered' with 'defaults,noatime,discard' or appent 'discard' to the options?

    @ploub, thanks!
    another thing i want to make sure is trim support for my ssd. i have this one. the 64gb version.
    i don't seem to find a certain source online, even the sandisk's page doesn't mention anything.
    is there a test i can run?
    edit: it does support trim, just for reference i used "hdparm -I /dev/yourssd" as root and i got:
    Data Set Management TRIM supported (limit 8 blocks)
    somewhere in the output.
