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

Technically, TRIM is not supported by Lion for non-Apple-branded SSDs, but there is a work around for this.
The procedure described here worked beautifully for me: http://digitaldj.net/2011/07/21/trim-enabler-for-lion/

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?

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,
Giovanni

No trim support in Lion.....disappointed!

I can't believe my OCZ SSD still does not have trim support enabled after updating to Lion. Come on Apple, even windows supports trim. Anyone else using SSD found any difference?

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.

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.

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!

Can't turn on trim support on APPLE SSD SM128

Hello,
I'm hving problem with starting trim support on my SSD (i'm new at this ssd thingy)...as stated in the topic its an APPLE SSD SM128...
I've downloaded and started the Trim Enabler app and rebooted my computer a few times, but still i get the same msg:
"the patch is active, but the trim is not working"!
btw, im on osx 10.8.3
Does anybody know what should i do?

I bought a used late 11' Macbook Pro which came with a apple braned SSD 120gb. I took it out and popped it in my old 06' intel core 2 duo 17" Macbook pro running lion. To enable Trim I downloaded Chameleon SSD, Works GREAT!!

Ohh I bought a Samsung 840 pro 256gb and popped that in my late 11' (Mt lion) Macbook pro using Chameleon SSD Trim support on it. That too works flawlessly!!!!!!!!
Good Luck!
Keep us posted.

Yosemite Patchless TRIM Support

https://github.com/Temptin/Documents/blob/master/Yosemite_Patchless_TRIM.md Apple started laying the groundwork for official 3rd party TRIM support as early as OS X 10.10.3, when they changed their IOAHCIBlockStorage.kext to understand a new Info.plist option that allows the user to force their driver to enable TRIM on non-Apple SSDs............

Logic 9, SSDs, new MBPs and OSX TRIM support

Gang, my 2006 17" MBP is on its last leg, so the rumored MBP refresh is timely for me. The rumored hardware refresh has the MBPs sporting the new intel sandy bridge architecture along with a 16GB SSD boot for OSX. There's also a rumor of the option of upgrading the Superdrive to a secondary SSD.
This would've been a 50/50 coin toss a year ago as I wasn't doing audio editing/songwriting. Now, researching this whole SSD write fatigue issue is driving me nuts.
Some say that write fatigue is very real. Some say the effect is negligible in newer drives and it's getting better every few months with new hardware. Some say the write fatigue issue is moot since the poerformance is still (mostly) better than that of a HDD. Others point to it not being an issue with Win 7 and Linux due to TRIM, but it is still a bugaboo on OS X due to lack of TRIM support.
So, I'm confused.
This really wouldn't be an issue if I was running an 8 core Mac tower with 10/15k rpm drives. Since I'm updating my laptop to another laptop as my only production platform, I really want to have the best portable package I can have performance-wise (setting aside the issue of ditching the ODD for a moment).
If the rumors are true, I could boot from the dedicated SSD, have my apps, VSTs and samples on the secondary SSD, and do all my writes/reads to the HDD. Is this a logical file layout?
For those that use a SSD, what has your experience been with it in audio production? Are you SSD-only, or in a mixed SSD/HDD environment?
This is all academic really, because the first thing I'm targeting in a new MBP is 8GB of ram. My current setup is only 3GB with Logic and a major VST like Omnisphere or Trilian. I can squeak by with freezing tracks, etc. If getting opting for the SSD means losing ram, then I'm definitely passing on the upgrade.
Thanks for any input!

Mixed SSD/HD here.
I didn't really see much value in having Logic (and other apps) boot any faster since I don't mind a) boot times as they are, and b) I actually appreciate some of those times when I can't get straight to it. Sometimes slow is good, it allows the imagination free reign.
I use the SSD for all samples, etc. EG - I use Omnisphere a lot and working off a hard drive is fairly mind numbing when clicking through sounds. It's now fast enough that it begins to feel like an old school synth in terms of patch changing. I'm happy.
This way is also 'write once, read many' so I get the best of SSD tech meantime.
Irritatingly expensive for storage, of course.

TRIM Support for AMD sb850

I've just bought an OCZ Octane 128GB SSD, formatted nad created an ext4 partition to host my root filesystem.
When I try to enable TRIM support for root filesystem (putting the discard in mount options) I get the following errors in dmesg
failed command: DATA SET MANAGEMENT
I've a Gigabyte GA-870A-UDE rev2 motherboard, the SSD is attached to one of the sata3 ports (managed by the SB850 Southbridge)
Any Ideas?

Does nvidia chipset drivers have trim support?

Specific motherboard NF980-G65, and SSD Drives in question are Plextor M3 Series PX-128M3 2.5" 128GB SATA III Internal Solid State Drive (SSD) http://www.newegg.com/Product/Product.aspx?Item=20-249-014&SortField=0&SummaryType=0&Pagesize=10&PurchaseMark=&SelectedRating=-1&VideoOnlyMark=False&VendorMark=&IsFeedbackTab=true&Page=2 and My older one ADATA S596 Turbo AS596TB-64GM-C 2.5" 64GB USB 2.0 & SATAII Internal / External Solid State Drive (SSD) http://www.newegg.com/Product/Product.aspx?Item=N82E16820211479. I heard that using the Microsoft Drivers was better then using the Nforce Drivers from this post http://www.sevenforums.com/tutorials/61869-ahci-enable-windows-7-vista.html?ltr=A. My ADATA SSD drive Sata port died somehow and Plextor drive is the new one ima get soon so doing some research the MB only suport Sata II but the Plextor is Sata III and I think backwards compatable why I might not get full speed out of the drive I wana optimise it as best I can as the main Boot up drive as I have 2 matching 1 Terrybyte WesternDigital Sata drives for storage/other games installed on. So Leave Nforce drivers after I install them or use Microsoft's tryign not to install the Nforce's or do a update driver after and switchign back to Microsoft's I know both drives support Trim as via there decription and as of now on this backup Sata Drive trim command via dos promt shows trim is enabled in windows but does the motherboard/nforce drivers support it? (I will be back to check on this post for idea's sugestions and responces to any more info that is needed)

ahh okie what about AHCI for the single SSD drive not in any raid array or anything? as I was reading on another page > AHCI and SSDs
Typically, many hardware review sites, as well as SSD manufacturers are recommending that AHCI mode is used with SSD drives. However, we have run our own tests here in the forum, and we believe this is misleading, only where SSD drives are used independently (ie not in a RAID array). from the MSI HQ User-to-User FAQ Hm now that I think about it I think I ment AHCI Not Trim. Must edit the other post.

My SSD install in Lion shows no TRIM support. How do I fix?

Hi folks. I had my new 2011 mini upgraded with an OCZ Vertex 2 SSD drive. I checked for TRIM support after a clean install of Lion and it says No. How do I fix this? Thanks.

I think some want to believe TRIM is needed; or, it was with older model SSDs.
The TRIM Enabler has a change log, and history of sorts.
SATA-IO has said that 3.1 specification will incorporate TRIM into NCQ (command queueing) going forward now that it is final and adopted which is a much better solution.
The lack of free space or having to reuse storage cells (a month's worth is a good number) and the background garbage collection will take care of your drive.
I would not. OWC does not recommend its use, and they just use Sand Force controller and firmware also.
Also, a lot of PC users set motherboard RAID, TRIM is not supported in RAID configurations, and that seems to be fine.
My Corsair SSDs (5) are 6 months and going strong.

Trim support in storport miniport driver.

Hello,
We have a storport miniport driver (open source at https://github.com/YanVugenfirer/kvm-guest-drivers-windows/tree/master/vioscsi) which we want to use with a SSD backend. I was expecting it to receive the SCSI UNMAP or WRITESAME scsi commands when I delete
a file in Windows 2012 but i see no such thing.
Looking at the documentation i see something about new trim support and the extended STORAGE_REQUEST_BLOCK structure but it's not clear how does the driver receive a trim. Can someone clarify? Where in this new structure do i get the trim? Is it in SRB_FUNCTION_IO_CONTROL? Why
aren't the SCSI UNMAP/WRITESSAME commands used?

Take a read of the following thread at Corsair. The first post describes how to use a command line to enable trim and how to install AHCI after a windows 7 install.

Trim Support in RAID 0 on a P55-GD65

I have some confusion regarding TRIM support in RAID 0. I have 2x80 GB Intel X-25M G2 SSDs in RAID 0 on a P55-GD65 mobo. I am not using a RAID card, and my OS is Windows 7 Ultimate x64. I just flashed the latest firmware update for the drives. According to the Intel SSD Toolbox, TRIM is not enabled. I have the latest Intel Chipset Drivers from Intel's site rather then the MSI downloads center. After doing some reading it sounds like if I back up my data, set the drives to ACHI rather then RAID, rebuild the array, and restore my back up, the drive will support TRIM. Is that correct?

If I am not mistaken, "TRIM" is generally a no-go in RAID-Mode conigurations.
