Success adding a secondary HDD

Mein Problem

I want to add a secondary SSD HDD in to my new Mac Mini.

Meine Reparatur

I did it followed the guide on ifixit websit.

The hardware installation is easy for me. And then I made a fusion drive in Mac OSX, but I forgot backup my OSX system firstly. So there was noting on the fusion drive. I used the Internet Recovery service from Apple site, but it's so long.

Finally, it's running better and I enjoy it.

Mein Rat

Don't forget backup your data and system before making a fusion drive.
