I'll admit that I don't know what Apple's GC routine is in OSX, but it's obvious that it's there and functioning, otherwise we'd see a plethora of complaints and outcries all over the internet about Macs slowing down like crazy. Just because I myself don't know what it is or is called, doesn't mean it doesn't exist, and again, even Gordon mentioned the evidence that it appears to exist, although Apple's not speaking up about what it is or is called.
I see. It appears you are admitting you don't know anything about the subject, or at least you didn't at the time you called Gordon out.
So How is it you decided to make this comment:
I think Gordon was just admitting that OSX doesn't need TRIM, and that it's really unnecessary, but got defensive about it, cuz that's the Kool-Aid that they've been trying to make us all drink. That's how it reads to me anyway, and I read it at least 3 times to make sure I was on the right path. Seems like Gordon pwned himself actually.
As for the Kool-Aid, the computer industry is chock-full of total BS that they like to push on us, saying it's necessary, when it's far from the fact. Garbage Collection routines may be necessary, but I believe that the computing industry is just being lazy and forcing us to use it, when using SSD's, rather than figuring out a way to make it operate automatically.
That's a pretty general condemnation there. Based on what exactly. I thought that what the trim command did , make it automatic I mean.
OOPs, Whats that? Gordon was right? Where's your link?
The last known info given about Trim support in Macs, that I could find, is actually from June 2010, where it's noted that the drives they're using do not sport firmware that's compatible with current Trim capabilities, thus they're not supported.
Lets see I read this article, http://en.wikipedia.org/wiki/TRIM_command
, and come to this Quote:
Older solid-state drives designed before the addition of the TRIM command to the ATA standard will need firmware updates, otherwise the new command will be ignored. However, not every drive will have an upgrade option. For those drives which do support the command, the operating system must also support the command. The table below identifies each notable operating system and when it first supported the command or when it is scheduled to support the command.
Operating System↓ Supported since↓ Scheduled to be supported↓ References↓
Windows 7 Final release - October 2009 
Windows Server 2008 R2 Final release - October 2009 
Linux 2.6.33 Feb 2010 
OpenSolaris July 2010 
FreeBSD Version 8.1 (Only for low-level erase) Version 9.0 (Proposed) 
Mac OS X Probably in the future 
Where TRIM is not automatically supported by the operating system, there are utilities which can send TRIM commands manually. Usually they list all free blocks as specified by the operating system and then pass this list as a series of TRIM commands to the drive. These utilities are available from various manufacturers
(Intel, G.Skill) or as general utilities (hdparm since v9.17).
So Trim is a 2 part deal Firmware already on the drive, and Software in the OS to tell it to do its thing. The article notes the firmware as part of the drives back in March 2010.
Yet you say as of June:
It's also noted that the new Macs (note: NOT the latest released ones, but future ones) will have drives that do support Trim, due to their firmware, and OSX will enable Trim for said drives, automatically.
It seems that Intel is behind this issue, which isn't surprising. Apparently Nvidia's chip sets are capable of communicating Trim commands, however Intel doesn't want them touching their hardware any more, and therefore the new Macs will use Intel chip sets, which it's still up in the air about where that's going to end up. Intel's not speaking up about what they're going to do, in regards to allowing/not allowing Trim support for Macs. If I were Apple, I'd be forcing them to cough it up, because they can't allow a greedy-assed company to destroy them, just because they're also in competition with them, not just in bed with em.
Now that is a really curious statement. Now, if the firmware is on the drives and just waiting for the OSX to tell it something, how is Intel to blame. What has nVidia chipsets to do with it?
I'm just trying to understand it all. You must have the knowledge, I mean you as good as said Gordon was an idiot or at least ignorant. So you have to have had something to base that on. So educate don't get all defensive. You made the call that means the burden of proof is on you. So I leave you with a quote from my previous post:
Now you chimed in saying with the hip shot; "I think Gordon was just admitting that OSX doesn't need TRIM, and that it's really unnecessary, but got defensive about it, cuz that's the Kool-Aid that they've been trying to make us all drink.". When as we see that is not the case. Mo was put in his proper place on history issues and that trim or at least garbage collection in some form (my words there) is in fact needed. But if you don't believe that it's ok its a free country. This is not, as noted, a mere opinion by Gordon it is documented proven fact many times over by many sources. It is proven that SSD's suffer without.
I admit I may have been a bit snide with my response with you but... Now and then I get annoyed when someone unpublished, unrecognized and most likely under qualified makes a blanket statement that can easily mislead some noobe such as myself. By the way what was "cuz that's the Kool-Aid that they've been trying to make us all drink" supposed to mean.
You said you thought Gordon was admitting OSX doesn't need trim. That implies that Trim is not needed. But you offer no reference to back it up. some people read these forums to learn or get up to date on things and true facts are needed not blind off the cuff statements. So let me restate the questions a little more clearly. Just to help your reading comprehension skills.
Why doesn't OSX need Trim or some equivalent?
Why is Trim or it's equivalent unnecessary?
If OSX is doing it in some way How are they doing it? And where can we see an informed methodical review of at least the results of Apples methods of dealing with the problems.
