Add SSD to a Fusion drive iMac

Hi

I have a 3TB Fusion drive and I just bought a 1TB 2.5" SSD (Samsung EVO 840).

I want to add it to my iMac as my boot disk and make the Fusion as storage.

Is there any way to do so without removing the 3TB HDD and break the Fusion?

I saw this product but than I'll have a useless Blade 128GB SSD:

My iMac configuration is:

27-inch, Late 2012

3.4GHz i7

32GB RAM

NVIDIA GeForce GTX 680MX

10.9.1

Only some models have blade connectors are your certain yours is one that does?

Have you figured out where and how you will mount the SSD there's not a lot of room in there.

If this answer is acceptable please remember to return and mark it.

I'm sure.

In your link it shows that every late 2012 27" iMac has it and mine has a fusion drive so it uses it now, right?

Yes - my mistake in reading, all 27" models do have it - but there's not a lot of room, how/where are you going to mount the non-blade SSD?

by

I will find a way to fit it in.

In the worst case I will remove the SSD casing.

So there is no way to connect it without removing something?

You have two storage device ports internally. One is a SATA (HD) and the other is an M.2 connector (SSD). Unless you have a means to convert the M.2 connection to a mSATA or SATA connector for your SSD you have not options at this point until a 3rd party offers a solution.

i did it back than..

I now have 1TB SSD + 8TB HDD (because the original 3TB died).

I used the blade to sata converter + a cable that splits the power from the HDD to both drives.

The SSD fits behind the HDD

How did this work out? I have a 3tb Fusion also and would like to just upgrade the 128gb flash side. Is this possible?

Sadly, we're still waiting for 3rd parties to come out with compatible M.2 SSD blades. Your other choice is to replace your HD with a SSHD (hybrid HD) to improve performance. As to switching out the SSD or HD you first need to break the Fusion drive using Disk utilities so each drive is on its own. Then you can switch things around and then re-establish the Fusion drive. If you put either drive you will corrupt the data. I would still strongly recommend you make a backup before doing anything here.
