Compatible SSD for early 2009 iMac 24" ...

Hey there!

I read a lot about swapping or adding a ssd to my IMac, but my main concern is more about the qualities of the drives out there. I heard that samsung are amongst the best. I've read a lot of bad reviews on the reliability of the seagate drives...

I was looking more precisely for that one :


But then, I have quite a hard time finding if it would be compatible or not with my cpu (early 2009 IMac 24" 2,66 Ghz). Some sites I looked on seems to say it is (but only for the 128 go option) (, some other seems to say that it is but only from mid-2010 27" IMac (

I know there are some issues with the fan speed control, but I can probably manage that with a thermal sensor cable and numbers of apps ifixit suggest.

What could go wrong if I would still install that ssd even if my cpu is not listed as compatible?

If it really is impossible for me to go with that one, would you have any suggestions or good experiences with some other ssd that could be compatible with an old cpu like mine :) ?

Thx for your Help!

Here is the specs for your system iMac 24" 2.93 GHz Core 2 Duo (Early 2009)

To start with your system can support any SATA II (3.0 Gb/s) drive HD, SSHD or SSD. The issue is making sure the drive you do get is able to run at this exact SATA I/O speed. Many (HD, SSHD or SSD) are fixed speed and may not be able to run in your system. So its important to review the specs to find the Interface supported line and that it clearly states it works running at SATA II.

Before you get into upgrading your drive you should think though the amount of space the drive needs to be. SSD's need more free space than HD's to last longer. I recommend no less than 1/4 be left unused. If you run a lot of heavy memory apps you'll likely need more (1/3). Do make sure you've maxed out the system (8 GB) if you are using anything higher than Lion.

Then the next issue is the OS you are using. You have two things pulling at you here the age of the system and what OS is best suited for the SSD. Ideally, you should be running Mavericks to gain TRIM services for the SSD, but that might be to heavy for your system depending on what you're doing.

The last issue here is the cost for needed SSD. While you talked about getting a 500 GB drive will it be large enough now that we know we need more free space on it? Also remember this is an older system so does it make sense for the investment given its lifespan it has left. Sadly, Apple won't be supporting this system in the next version of OS-X (MacOS Sierra).

So thats a bit more to chew on here. While its nice to have the greatest drive in the system it may not be ideal given the systems age.

This is where maybe going half way would be a better direction. How about going with a SSHD drive? While you pointed out you have seen reports of problems with Seagate drives I can tell you most are related to older versions and all of the HD vendors have had their bumps (thats also true with the SSD makers as well). I should say I've not seen that many failures and we have quite a few Seagate SSHD's in service (both laptop & desktop systems).

  • If you are still thinking on going with a SSD then I would go with the Samsung 750 EVO (500 GB)

The 750 EVO is the lowest priced SSD Samsung makes. You don't need anything fancier here. You'll need an adapter frame to support the smaller SSD (2.5" vs 3.5") if you are swapping out the current HD for the SSD. As for the thermal issues, none here! When you take the old HD out you'll take the stuck on sensor and transplant it to the new drive (either). Here's the IFIXIT guide you'll need to follow: iMac Intel 24" EMC 2267 Hard Drive Replacement

The other option here is to switch out the optical drive for a smaller SSD as your boot drive. Here's the IFIXIT guide to do this: Installing iMac Intel 24" EMC 2267 Dual Hard Drive and here is the special carrier you'll need: 12.7 mm SATA Optical Bay SATA Hard Drive Enclosure. In this config you could go with a smaller (cheaper) SSD option as you'll only have the OS and apps on it leaving the rest of the drive for the system to use. All of your deep content (docs, music vids etc...) stays on the HD. This would be my second option here.

So there you have it soup to nuts on your options!

Focus on how much space you'll need on the drive and what is the most economic solution for you balanced with the performance you are aiming for. As to durability look at the warranty the drives offer I doubt you'll still be using this system before the warranty expires ;-} Good Luck!

Wow! Now that's what I call an answer...

Thanks a lot for all the tips. I have gone through the different ifixit guide already and in fact, that's what made me consider keeping my old drive and condemn my optical drive so I could keep some storage with the original HD. But finally, I prefer to keep my OD just in case. Why only the 500 go SSD? Well it was essentially a question of $$ since I would use my external HD for all the docs/files I don't need on a weekly basis.

As for the OS I'm using, I've just installed El Captain last week and I can feel my cpu working pretty hard, hehe! At least, my DRAM is at 8 go for as long as I can remember.

I've look for the SSHD also because of the great compromise between performance and storage. So I'm glad to hear your feedback on this product. Thanks for pointing out the fact that I'm limited to SATA 2. I could'n find the info in my system preferences...

So after all, I think I'll go with the seagate SSHD!

Your answer was really helpful, thank you!


Yes, I think the SSHD is the best direction for you, if you want everything internal.

Since you appear to have an external drive which is hosting most of your stuff I wouldn't dismiss the SSD option just make sure you leave enough space free on it (keep it fit & trim). Then use the external all of the time for your work. Hopefully this drive is FireWire - USB2 is so sllooww ;-}

I would try to find an external FireWire 800 case 3.5" to put your current HD into (if thats possible, they are getting hard to find). That would allow you to migrate your user account info & apps to the new drive and repurpose the drive as a backup drive.

Happy to help out ;-}


Nice! I like the idea of keeping the actual drive but in an external case. I guess the migration step shouldn't be so hard. Here's what I found :


My only concern is that they don't specify SATA 2. By "SATA" do they mean SATA 1 or...?!

Haha! I laugh when you talked about the ED being on usb 2 or FW. I did a back up a few days ago and it was soooooooooooo slow! (yep, I've bought it with usb2 at the time. Really, don't know why when think about it now...)

Last question here (for now :p). I guess TRIM works also great with a SSHD?


Nvm about the SATA compatibility. I found the info :


•Hard Drive Interface: SATA II 3Gb/s


You should be fine here the SATA to FireWire case can handle a slower drive (downward compatible)

The SSHD manages the onboard SSD as a cache so the OS has no clue its there. As such no need for TRIM services or any other OS level service here.

The onboard SSD's interfacing is managed internal in the drive so nothing to worry about here
