For an iMac with a Fusion drive, does removing that drive and replacing it with an SDD remove all traces of “Fusion-ness” from the computer? In other words, does the drive that is getting removed contain everything that is “Fusion”? Or, or is some other step also required when replacing a Fusion drive with an SSD … in order to “de-Fusion” the computer? I’m wondering if the drive swap is all that is needed. Thanks. -Allan
You need to break the fusion drive set into the discreet drives following this: How to split up a Fusion Drive. Then you can replace your HDD with a new drive. Remember your system still has the blade SSD on the back side of the logic board as seen here
Which is the second drive that makes up the Fusion Drive set (HDD & SSD)
