Answer to: Where is the SSD of the FusionDrive located?Hi Marco Tust, The SSD of the Fusion Drive should be located at the back of your logic board, right underneath the CPU where you see a long card-like (resembles of an Airport card). You have to flip over the logic board since it is on the back. If you want to buy an SSD to replace your HDD, you don't need to take away the SSD in the back of your logic board. You can simply put a new one from your HDD. Hope that helps.
