Macbook Pro 2011 Apple SSD supports TRIM

Folks,
I'm not sure I'm reading this right... so, please set me straight if I'm reading it wrong.
I ordered a 15" Macbook Pro off Apple's site on release date with SSD, ram and display upgrades.
Does the screen shot say the SSD can support TRIM or OS X can support TRIM, or both?
I only question because I think this is a 10.7 'support' item, not 10.6.6 which is what I have from the factory.

Thanks!

Wow, well Lion Beta is out.
 
Interesting. Maybe the new MBPs have a one-off build of 10.6 that does support it somehow. Otherwise, I don't know what that means.
 
Wow, I did not expect that. Mine arrives in a couple of days with a 128 GB SSD. Hopefully I see the same!
 
Lion will support TRIM so it's a good thing the Apple branded SSDs are starting to support it as well.

The OS will report TRIM yes or no based on the hardware specifications, doesn't mean the OS supports it.

That's not true. Numerous SSDs that do have TRIM support built into the firmware (Intel, OCZ, Sandforce) all show "no" in System Profiler. The "Yes"s only started appearing recently with Lion. If what you say is true, Lion doesn't really support TRIM either, since the "yes" is the only evidence we've had that TRIM is indeed supported.

Furthermore, older Apple SSDs also show Trim support: Yes in Lion, so this isn't a case of Apple using TRIM-supported SSDs.
 
so what's the consensus on this one? Is there TRIM support in the latest shipping version of SL?

As cool as that would be, it is unlikely that the new 2011 MBP's shipped with a different version of SL than the current 10.6.6 out in the wild.
 
I would call that an extremely weak claim for TRIM in Snow Leopard. It's coming this summer in Lion.

Of course it's a different build. That happens very time new hardware is released. It's build 10J3210. I don't know if it supports TRIM but it's sure looking like it does on Apple SSDs.
 
The kernel is different on these builds than the previous 10.6.6 SL. It is Kernel 10.7.1, which is greater than the kernel in Lion (10.7.0), so I wonder if this plays into it???
 
I got a 15" MBP (last week) and mine also says "Trim Support: Yes". I also read that the MacBook Airs did not show any trim support. I'm not sure what it means. Does the operating system have a utility written into it to assist in the "garbage collection" of deleted files, or does the ssd firmware take care of the process? In any case, the Lion OS is due out this summer, which is expected to offer support for the solid state drives.

I don't think anyone has a definite answer yet. We really won't know until some REALLY technical blog like Anandtech does a thorough review of the machine (not just a couple of generic benchmarks, but more comprehensive ones, as well as disk stress-testing).
 
Yes, mine has TRIM support. Word is that it's only on Apple SSD's, though (same in Lion).
 
Ok, well as you've moved my thread Mr Mod?? You have to be the strictest mods on the web on here.... It's a pity the title of this thread states that only the 15" model as Trim rather then imply it could be ALL models that support it? Any chance of renaming the thread?

I shall clear up all the questions being asked in this 'origional' thread that according to the link I posted Trim IS supported but ONLY on Apple's SSD drives at present. Why else would it state Trim - Yes??
 
So I may've made the right choice in picking the official Solid State Drive afterall, even if it's unfortunately not a SATA III device. I really must wonder though, why does it have to be an Apple SSD (this requirement kinda sucks) and how would they restrict support for a standard like this in what in all likelihood is a rebranded drive? I wonder if TRIM is enabled by the drive itself or by a setting configured during the B.T.O. process.

My build is 10J3210.

I have a 2011 MBP 13" that I upgrade with a 128GB OWC Mercury Extreme Pro SSD and the system profiler shows TRIM Support: No.

SL 10.6.6 probably only enables TRIM for Apple SSDs.

It's not something they enabled in the "BTO" processes. It's as simple as the 2011 MBP's are running a different version of Snow Leopard than the 2010 ones.


I have two 15 inch MBP's and they're running:
2011 MBP SL 10.6.6 Build 10j3210
2009 MBP SL 10.6.6 Build 10J567

Both are "up to date" but they're running different builds. Apparently the 10J3210 has something that can recognize the Apple SSD's and enable trim support.

It would be really lame if Trim support (whether it be in SL or Lion) was only limited to Apple SSD's. If they incorporated it into the OS, why not enable it for EVERYONE who has a SSD.

The Apple Inside article I linked to stated that currently it WAS only for Apple's own SSD drives.
