I have this exact machine and took it in. It has worked flawlessly with a crucial 256GB ssd. They did have to order extra parts but it works
I think that will put Crucial M4 128Gb
What's this say? Do not be a problem?
After reading the twam.info link listed earlier, I had my local AASP install a Cruclal M4 256MB SSD in my wife's mid-2010 27" iMac last year.
It's performed flawlessly, and it's nice to still have the HDD and ODD. Since it was done with all Apple parts, and by an AASP, my warranty and applecare coverage is still good.
In the end, it cost about as much as it would've had I just ordered it from Apple. The only real gain is that the Crucial M4 is a better SDD.
I paid $71 for parts (the two cables, the pressure wall mounting bracket, anda a package of screws) and $222 in labor.
Firmware? Updated or not?
I've installed Corsair ForceGT's, Intel's, OWC's, Samsung's and OCZ's in 2009, 10 and 11 model iMac 27"ers and all have worked just fine.
Most if not all of the SSD's I've bought came with a 2.5" to 3.5" adaptor in the box (for sure the ForceGT and Intel did) the other brand I did for friends and each had an adaptor but I did not ask if it came with the drive.
I would suggest to simply have the SSD added to the computer in addition to the HDD so you don't have to deal with any fan controlling programs, it isn't hard to do or setup but if someone doesn't want anything extra to deal with then don't.
All you would need to get would be a slimline SATA+Power plug to add the drive to the empty SATA connection on the logic board and either the bracket pieces or double sided 3M tape to secure the drive down inside the computer.
Somewhat on topic...
Considering the wealth of experience you have in this area, I'll throw this one to you, mmomega:
I have a mid-2010 27" iMac with a single 1TB drive factory installed. I'm preparing to remove the 1TB drive and replace it with a pair of 512GB SSDs (Samsung 830) using a 2x2.5 to 3.5inch adapter. I will, therefore, need to utilize the third SATA port on the iMac (I'm keeping the optical drive as is). I'm reading mixed reports of the cable required to get the job done. Do I really need this: Link to Apple part or will this get the job done: Link to Generic part?
Is the first of those two for 2010 iMacs, the second for 2011 iMacs? Or will the second option work with the 2010 without problems?
Thanks so much.
Nathan
