Upgrading a Mac Mini (late 2014) to a combo SSD + HDD

[Spigaw]

Hey there people!

Maybe some experts around here will be able to help me, as I could not find a definitive answer anywhere about this issue.

I recently bought a Mac Mini (late 2014), with these characteristics. I want to upgrade it to a combo SSD + HDD because you know why, but I can't find a way to know if it is possible or not to add a second SATA connector (like some you can find really cheap on Amazon), or if it comes with a PCI connector (like it seems to be the case, via iFixIt).

So i wonder what's the best solution:

1. Buying a standard SATA SSD and replace the HDD with it
2. Buying a standard SATA SSD as well as a kit with two SATA connectors and keep both in the Mac
3. Buying a NVME SSD and plugging it in the elusive PCI port.

Thanks in advance for your help!

The PCI connector for a 2014 Mac mini that allows you to fit another SSD looks similar to this, I believe this is what's shown in iFixIt. Replacing the HDD requires removing everything from the case, adding this connector allows you to add an NVMe SSD which for a reg Mac mini would let you create a fusion drive.
