Time Machine vs Clone

I was thinking of adding an SSD to my iMac Mid 2011, which I have learned has an extra SATA slot on the back of the logic board. This way, I could keep my old drive, get sped form the SSD, and keep my optical drive. I wanted to create a fusion drive out of them, and was wondering what would be the better option: using a Time Machine backup, or creating a clone of the old hard drive on a separate one, fuse the HDD and SSD, then cloning back the separate hard drive to the newly created Fusion Drive. I know Time Machine backs up all of the files, but does making a fusion drive also install the OS?

Thanks!

You should always keep at least two solid backups.

(especially if your going to perform surgery on your Mac)

Personally, I use Time Machine and no less than 2 bootable clones with CarbonCopyCloner.

(Time Machine on one drive, a daily clone on a second drive and a weekly clone on a third drive)

You have a couple of options in this scenario.

1. You can simply install and run macOS on the SSD, then access your user data file on the existing internal hard drive.

(I think that you'll be surprised by the increase in speed, stability and reliability in this scenario)

2. You can setup a Fusion drive, but it requires erasing your existing hard drive and restoring from backup.

(there is no real speed difference over scenario 1 and it is harder to fix, if something goes wrong with one of the drives)

Ok, thanks!
