What drive connectors are used for a Fusion Drive?

Your system offers two SATA interfaces! Running at SATA III (6.0 Gb/s) you can see the two ribbon cable connections mounted on the logic board here just popping off the bottom cover.

If you don’t have both connections then you’ll need to add the second SATA cable connection Mac Mini Late 2012 Dual Hard Drive Kit installieren and the second drive.

A Fusion Drive’ed system will have both cables present, Apple didn’t sell to many 2012 models with Fusion Drives as there was little benefit given the slower 6.0 Gb/s I/O speed. The 2014 model changed that introducing the custom Apple blade SSD.

Today the cost of a SSD is so much less than at that time point getting a 512 GB or even a 1TB SATA SSD is not that big a stretch for most people today so the whole idea of a Fusion Drive is mostly dead as a single SSD or even a dual independent SSD & HDD or dual SSD drive’ed system makes better sense.

As an example my own 2012 mini has two 2TB SSD’s and I use it as a media server for my music and videos.
