iMac 27" SSD Upgrade - Important Tip!

Hi,
I read the whole thread but got a little lost with all the TRIM talk. I just bought this drive:
SSDSA2MH160G2C1
How can I tell if TRIM is installed? From the discussion I'm not really sure how to get rid of it or even if I can. Are people getting rid of TRIM or just leaving it? If I leave it will I take a big performance hit?
I would guess that you should use the included utilities to check the firmware version currently on the drive, and then google that firmware version, or look it up on their website.
If you have the TRIM enabled firmware, I believe it can cause you some degradation and speed loss, since the OS doesn't support TRIM, and that ver. of the firmware DOES disable the "voodoo" that's already on the drive.
Thanks for the reply. In the description of the drive it says:
The Intel X25-M SATA Solid State Drive features the Intel SSD Toolbox with Intel SSD Optimizer, which manages the health and boosts the performance of your drive.
Sounds to me like it has the "voodoo" disabling firmware. Maybe I'm making to big of a deal about it and it will run fine as is?
Looking at the DVD drive in the iMac this might be an option also. http://www.mcetech.com/optibay/
Maybe the one for the 17" MacBook Pro fits the iMac.

$99 is a bit steep, but it looks like it will work and it includes a USB case for the optical.

Hi,
Thank you for your inquiry...
Yes, the OptiBay will work inside the iMac as with the Mac mini and can be used to replace the superdrive with an SSD. It would also include and enclosure so that you will still be able to use your SuperDrive externally via USB.
The CD slot does not need to be plugged since CDs and DVDs enter in less than an inch before they contact the solid OptiBay and will not go any further. There is no way to jam them in.
Please let me know if you have anymore questions or need any additional information or would like to order a unit for your iMac.
Best Regards,

You want the 02G9 firmware. This is the pre-TRIM-enabled firmware. As to how to check, I am not totally sure, maybe someone else can shed some light on that? I would assume if you use Intel's SSD tools they will say somewhere, but I believe they only run in windows so you will have to use boot camp or parallels for that I think.
In terms of performance, the pre TRIM Intel G2 drives have about 36MB/s for small file random writes both used and new. Once the TRIM firmware is installed, the drive assumes you are using TRIM which is not supported in OS X, so after moderate use your performance of small file size random writes will drop down from about 38MB/s new to around 17MB/s used. This is still much much faster than any HDD and most SSDs in fact, but obviously you want to get as much performance out of it as possible. If you do have the TRIM firmware, the only workaround I know of is to run the intel SSD tools periodically while using windows 7 in boot camp and wipe the drive clean using TRIM. Then restore from your OS X backup.
However, I have not heard any reports yet of people receiving drives with the new firmware already installed, so I would say chances are pretty good that you will have the original firmware on your drive still.
I actually picked on up yesterday even though I will prob not be getting my iMac until January because I really wanted to get the old firmware. I managed to find a store that had a drive that was packaged on Oct 8, so I'm confident it will not have the new firmware. Best of luck to you.
If anyone knows specifically how to check the firmware version of the Intel drives via software or any other means please, do tell.
Also I just want to emphasize that with any SSD, the performance degradation issue only affects write speeds, not read.
Thanks for the info. I will post back here after I get mine and take a look at it. Should be here today. I'm almost tempted not to do the switch. My i7 27" is working perfectly. Not a single flicker, quiet as a mouse and no yellow tinge.
The firmware version is printed on the label.
If you already installed it, you can check the S.M.A.R.T. info. Mine reports 2CV102G9, though on the label it just says 02G9.

Micron just posted 4KB Random IOPS numbers, guess what? its ahead of Intel's enterprise SSD by 10 percent on SATA 3 GBs, and 33 percent on SATA 6GBs.
http://www.micronblogs.com/2009/12/you-asked-for-it-realssd-c300-random-iops
This card is turning to be real Intel killer. Note that Micron is the company that makes nand chips for Intel SSDs, and yes, they made the nand chips in the G2 drives
Now if only they post random 4kb reads and writes
I've also heard ppl say that you should change a few of the settings on the Mac. eg:-
dissable sudden motion sensor
enable don't sleep, no safe sleep
apply noatime
disable spotlight
don't defragment
Any others??
Also, I'm not sure if it will work OK but once I get my SSD I was thinking of placing my Music, Pictures, and Movies folders on an external HDD. I was possibly considering doing this for the Desktop folder as well. Then make an alias of them and place these in the Users folder on the SSD replacing the original folders. Hopefully the OS will treat them the same.
My plan is to replace the ODD with my intel g2 SSD and use the optical as external.
I guess I would go this way http://newmodeus.com/shop/index.php?main_page=product_info&cPath=31_32&products_id=201 if I had time and patience or could find a store in Europe that sells these..
Until then.. duct tape it! (at least for me)

1st gen micron controller were very bad, and degraded quickly. I'm not sure if the speeds you are reading about are sustainable. For a quick chart on SSDs http://www.pcper.com/article.php?aid=736
The G2s are in short supply and new inventory will probably have the new firmware.
Sounds like Vertex on a mac is probably a better longterm performer than the Intel G2s?
also, regarding the 2 pint jumper for the 3.5" drive spot...
the factory installed drive has modified firmware that reports to these imacs. while replacing my superdrive with a SSD, I also upgraded my 1TB Apple drive to a 1.5TB drive that I already had. even with the temp sensor connected properly, just as it was with the original drive, i still got 3,500rpm + fan speeds for the HDD. so I swapped out the 1.5 and put the original 1TB drive back in and my fan speeds went back down.

Balls! That sucks! I REALLY should've gotten the 2TB drive. Dangitall. Why'd Apple have to go and do that?
I think you meant JMicron company who made that controller. I'm taking to the makers of the NAND Chips (the actual memory that Intel is using (80GB, 160GB) not the controller. It was made by the company Micron. They didn't made that ******* controller.
=================
Guys, I'm sorry if I'm hyping this up, but this is a very promising SSD, Intel has been dethroned in the random 4kb write.
Basically Intel lacks sequential write speed, which is roughly around 70mb and 100mb/sec in 160gb variant, as compared to the competitors' 200 mb/sec ++. But low and behold an SSD which has sequential read 260MB and 204 mb/sec sequential write, and around 60MB/sec 4k random write speed

here's hoping the independent reviewers like pcper and anand could get the hands of this new gem.
I noticed that the one used in LegitReviews is an older version, now I welcome anyone who has the Intel G2 drive can download the benchmark and post the results.
ah..
... ok, explicatives aside, let's all be more objective than just dumping information from a company PR website.Now, show and tell hour, how do you plan to install their card in an imac?
The G2s are in short supply and new inventory will probably have the new firmware.

No it is much slower than the X25M (even the G1) at 4k random reads and writes both used and new.
Now, show and tell hour, how do you plan to install their card in an imac?
You can install it without the card and use SATA 3Gb/s and it's still faster than the X25-Ms it seems.

I ordered a similar product from a french vendor: http://www.macway.com/fr/product/14...port-disque-dur-macbookmacbook-pro-unibo.html
It took only a few days to ship this to Germany. MacBidouille has a review of it too: http://www.macbidouille.com/news/20...our-remplacer-un-superdrive-par-un-disque-dur
(TIP: Use google translator if your french is as rusty as mine)
Unfortunately I'm still waiting for my iMac to ship, will be another week or two until I can finally use the Intel SSD.
a very cheap method is following:

yesterday i opened my i5 again and tested following adapter (SLIM-SATA --> SATA), appr. 10 Euro / 14 USD
If you didn´t move or pull your imac, you can fix the ssd with tape, but it´s not recommended.
With new and cheap adapter everything works perfect.
Silent and fast system
