LION APPLE SSD TS128A Trim Support = No!?

I currently have a Mac Book Pro Mid 2009 with a APPLE SSD TS128A.
After install 10.6.8 and recently LION 10.7.0 my Trim support is still set to "No."
Is there a way that I can enable this? Or is my drive unsupported? I believe this drive was manufactured by Samsung when I had the bottom open when upgrading the RAM.
Let me know if you are havig the same issues and if you've figure away to enable Trim?
I don't know if the drive needs a firmware update which I was looking at: http://goo.gl/kh8KD
Thanks in advance to anyones attention on this matter.
Here's my System Profile if helpful.

Have a look at my blog here: http://www.markc.me.uk/MarkC/Blog/Entries/2011/4/17_Enabling_TRIM_on_OSX_for_any _SSD.html
This hack works on my 2010 Macbook Air, and my 2011 Macbook Pro running LION. The 2010 Macbook Air obviously has an Apple SSD in it - I still needed this hack to enable TRIM.
As with anything like this make sure you backup first. I've had it running since LION was released and it's been fine so far.

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?

Does Apple ssd ts128a supports trim?

I just bought a second hand macbook pro (mid - 2012) with an Apple SSD TS128A. After a fresh install of Yosemite 10.10.2 system profiler shows that trim disabled. Am I doing something wrong? As far as I know, Apple SSD supports trim out of the box. Any help would be appreciated!
thanks in advance

Apple SSD TS256 TRIM not supported?

I have an Early 2009 17" MacBook Pro, which I got from Apple with a 256GB SSD already installed. It shows as "Apple SSD TD256" in the System Information panel. I've read that Mac OS X Lion supports TRIM for ALL APPLE SSDs, yet it says "TRIM Support: No". How do I fix this?
As stated above, this SSD came DIRECTLY FROM APPLE in the original build of this computer. This is NOT an aftermarket SSD.
Thanks.

It appears that Apple has no idea either:

MacBook Pro and an Apple SSD TS256A - TRIM

I have a MacBook Pro (15-inch Early 2008) and an Apple SSD TS256A. When I looked up the Toshiba part number, it said that TRIM was supported, but on 10.6.8 and 10.7, TRIM was never enabled. This drive was pulled from a 17-inch MacBook Pro from Mid 2010 I believe, and IS an Apple drive, so TRIM should work, no?

I have the same drive and Trim Support isn't enabled either. I've searched the Internet high and low and still can't find any mention neither of why it shouldn't work with our Apple SSD's nor anyone who has this same drive with Trim support enabled.
It's quite frustrating to be honest. All I keep getting from Apple is that it should be enabled for all Apple SSD's.
Of course that doesn't help me much because it is stil disabled. I was hoping that upgrading to Lion would have fixed the issue somehow but it didn't change a thing.
Hopefully someone can help us.

MacBookPro3.1 SSD and TRIM support?

Hi,
I recently replaced my HDD with an Intel X25-M (G2) 160Gb SSD drive and the mac is now _really_ fast. What I can tell from searching the net, is that the OSX operating system I'm using (10.6.4) is not yet supporting the TRIM feature of the disc. Eventually, the SSD could become slower...
Is there any information available to shed som light on this matter, such as:
a) will it be supported by Apple OSX in near future?
b) will I have to bother about it?
c) what else do I need to do in order to keep my SSD happy and fast?
Windows 7 do support TRIM and Intel provides the necessary (ToolBox) utility for Windows OS versions, but not for OSX.
Anyone?
Thanks in advance,
/Peter

I've done quite a bit of research on this subject and here's what I have come up with.
Based on anandtech's knowledge and reports, all of the Apple sold SSDs are OEM drives from either Samsung or Toshiba, and they all run custom firmware
source: http://www.anandtech.com/show/3991/apples-2010-macbook-air-11-13inch-reviewed/4
I would say that this is what's going on:
1.) Apple's SSDs run their own custom firmware and take care of drive degredation in a custom, non-industry standard way (aka TRIM) -- what a surprise, just like everything else Apple does.
2.) Apple has done this on purpose so they can make money selling SSDs for more than a standard (non Apple OEM) SSD would cost you.
3.) Apple will never implement TRIM; they want you to buy their drives with their firmware, which by all accounts, do not need TRIM and do not suffer from poor performance after extended usage.
Consider the facts -- Windows 7, Linux, BSD, [insert every other os in the world here] has supported TRIM for over a year now. It's not hard to implement; maybe 20 lines of code at the most? All it does is pass an ATA command from the SATA controller to the disk at the right times.
If you want to use a non Apple OEM SSD, I would say there's a more than likely chance it will become slower after 5-6 months of usage...Depending on the level of degredation, class of drive, how much free space is left on the drive, it could be noticeable.
Some users have reported using non Apple OEM SSDs successfully on OS X, and some have run into problems.
A few notes:
1.) A degraded drive can be reset to factory condition by using a secure erase program. You would have to back your data up, secure erase the drive, then do a restore. Secure erase of an SSD takes about 1 minute, plus the time to backup and restore depends on what kind of storage you're backing it up to \ restoring it from. This is more or less a band-aid solution for using an SSD on an OS that has no TRIM support, and should really only be done if you are experiencing problems.
2.) SLC drives are a LOT less susceptible to degredation than MLC drives. Intel still has not implemented TRIM support for the X25-e series drives...some people say that SLC drives still need TRIM, but in my experience (I've been using the SLC Intel x25-e drives for over a year and a half now), they don't. They're a lot more expensive though..by a huge margin.
3.) The less free space an SSD has, the more chance it has at becoming degraded. The obvious solution here is to store media and larger files on a NAS, and then keep only important applications and the OS on the SSD.
I hope this has helped answer some of your questions.
One more thing, according to Anand, the Kingston’s SSDNow V+ Series and the SSDNow V Series work very well on OS's without TRIM support (OS X). If I were you, I'd go with that over the Intel drive. I've never used a Gen-2 X25-M, only the Gen-1 (abandoned and discontinued by Intel, replaced with Gen-2, never had TRIM implemented and never will); and on Windows XP, I experienced stutters and slowdowns after 6 months. I used the "band-aid" solution to get the drive back to health, and then I got rid of it and picked up the 64GB V series (http://www.newegg.com/Product/Product.aspx?Item=N82E16820139132) -- unfortunately, that was around the time I switched to Windows 7, and I've never used the drive on OS X, so I can't confirm what Anand is saying; but I would take his word for it.
Since you already have the X25-M, I would keep an eye on things -- if it gets slow, back it up, do a secure erase (there's tons of programs out there, hdparm on linux is probably my favorite and the easiest to use), then a restore. Should give you another 5-6 months until you start experiencing problems again.

TRIM Support in Mac SSD

I am about to purchase my first Mac and Im so excited. But before I do I have a question about the SSD. I was not planning on buying the SSD, but instead just going to some 7200RPM HDD but realized the price was only an additional $90, a price you can not just go out and buy one at.
My only concern is the lack of TRIM in Mac OSX. Now, their is speculation (and partial proof) that Lion will have TRIM support, but from what I have researched TRIM is also a hardware variable and not just software. Does anyone know if the new MacBook Pro's SSDs offer TRIM support? Also, will my SSD, by Summer hopefully, be negatively effected by the few months of the lack of TRIM?
Thank you so much,
Ben

You do not need to run any UNIX (or any other) programs to 'TRIM' the drive. If the drive firmware supports TRIM (as all newer drives do) and the operating system supports the TRIM command, you will benefit from this feature. The way TRIM works is this:
When you delete a file from a drive, the operating system marks the space used by the file as free so it can be used again. On a mechanical hard drive this works fine and the space will get written over as needed. Unfortunately, the SSD does not know the difference between erasing a block and writing over it with new data, so they are treated the same. The problem that occurs with SSD is that each block on the drive has a limited number of write cycles it can withstand before failing so the SSD firmware tries to spread out the usage of blocks on the drive by a process called wear-levelling. This ensures that the drives last as long as they need to, but results in fragmentation of the drive. This is a lower level fragmentation than what is typically referred to when discussing hard drive fragmentation and is not really related. This low level fragmentation can result in reduced performance of the drive over time, as blocks are erased and data is moved around by the wear-levelling.
The drive manufacturers have worked wonders trying to minimize this effect with intelligent firmware, but it is still a measurable problem. This is where TRIM comes into play. If the TRIM command (a low level drive command, not something you run from within the operating system) is supported throughout the system, deleting of a file will cause the operating system to issue TRIM to the SSD instead of just marking the blocks as empty as would be done on a mechanical hard disk. The SSD then knows that these blocks are no longer needed and the drive firmware can then clean up more efficiently. The drive firmware will show the space as available (because it is) but will not actually perform a write to that part of the drive until a later time, when enough blocks are ready to be TRIM'd all at once. This works in conjunction with the wear leveling to reduce wear on the flash cells and prevent fragmentation from occurring. For a more detailed description of TRIM, I recommend checking out the articles by Allyn Malventano over at PC Perspective:
http://www.pcper.com/comments.php?nid=7488
That site is mostly geared towards Windows users, but the basics of SSD operation are the same, and Allyn is definitely an expert when it comes to storage technology.
As far as over-provisioning goes, this provides a way to reduce fragmentation without the need for TRIM support (although the SandForce drives also can do TRIM). Over-provisioning involves setting aside a certain amount of flash memory on the SSD (7-28% typically) that is not available (or visible) to the operating system. The firmware uses this extra storage space to more efficiently defragment and wear-level the drive and it is transparent to the operating system. This is why an Intel X25 G2 drive will benefit more from TRIM support than a SandForce based drive like the OWC or Vertex series ones. The above mentioned site also has some good articles about over-provisioning, including comparisons of the same drive with 7% and 28% overhead. It boils down to this: if you have a SandForce drive, TRIM support is not as important because the drive does a good job on its own. If you use a different SSD, TRIM support is very beneficial, and we should all hope that OS X delivers full support for TRIM in the near future. Also, the added expense for the enterprise level (28% over-provisioned) SandForce drives is normally not justified, especially in a single drive setup.

MBA, SSD, Windows 7 (or XP) and TRIM support

I have a 2011 MBA with an SSD and I want to install Windows 7 as a VM and/or Boot Camp. Does the MBA SSD need TRIM support? What's the best way of installing Windows 7, VM or BC, in terms of keeping the SSD healthy?
Will not having TRIM support cause SSD performance problems down the road?
Is installing XP a good or bad idea on a MBA SSD?
TIA

You have TRIM support on your MBA.
You should have no issues on any of the scenarios you contemplate.

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.

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.

Lion RAID0 SSD TRIM support

Hi all,
From what I've read so far it would appear that if I go to a RAID 0 SSD setup in my Macbook Pro... I'll lose TRIM support, even if both disks support TRIM by themselves?
I've got an Apple Supplied 128GB SSD and a Samsung 470 series 128GB SSD... I was thinking of reinstalling Lion (yes I have the bootable DVD) and configuring them in RAID 0, mainly to get one large 250-256GB volume...
Also, a lot of people are saying that 64Kb stripe size is the way to go....
Finally, someone mentioned about putting the disk utility into developer mode to elinimate the recovery partition off the Apple SSD?
Thanks for all feedback.

Cindy,
Thanks for the quick reply. If I'm understanding correctly, the SCSI unmap command was implemented in last November's Solaris 11.1 release but has since been disabled due to performance problems. I'm running the original November release with no updates so can I assume that SCSI unmap is enabled on my system? If so, do I run any risk of data corruption by staying with my current version? I'm currently running Solaris 11.1 from a SATA SSD.

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?

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 for SSD in OS X Lion

Greetings All,
Have read up on this and apparently not Apple SSDs aren't getting TRIM support. Does anyone have any solid info on this? Also, is there a completely dependable way of switching on TRIM support?
Any help would be greatly appreciated :-)
Cheers,
Edmond
PS - it's for an OCZ Vertex 3 240Gb Max IOPS drive.

you welcome )
But Edmond, trim can NOT cause issues - it just will give you no benefits and slow down SSD, if it is based on SF 2xxx controller. I detailed this here: https://discussions.apple.com/message/15649687#15649687 and even more details in discussion here: https://discussions.apple.com/thread/3194668?start=0&tstart=0

How can i upgrade my apple ssd with SATA300 and TRIM support

i pick an 256GB ssd from my MBP and install it on my computer.
win7 reads it as "APPLE SSD TS256A" and the firmware is "AGAB0202" but it only shows SATA150 support, not SATA300.
in the test it also show 130MB readspeed.
the ssd model is THNS256GG8BBAA, does apple has an firmware update for this ssd to support SATA300?
