If an SSD drive can be added via SATA, does the system view this as a separate drive or as a singular unit like as seen with a fusion drive set up. Thank you.

It would be an independent drive unless you took steps to create a Fusion drive by combining it with the PCIe stick.

Keep in mind that significant, delicate disassembly/reassembly is required to replace the internal SATA drive. Not recommended.
If economy is a prime consideration you could use this type of setup which I use:
This allows me to easily swap out other SATA SSDs as needed. It sits behind my iMac so it's somewhat out of the way visually.
Nope, for internal. However if you put it in a Thunderbolt 3 enclosure you can use it as an external SSD.
Can a SATA connected SSD be added to a 2019 iMac that shipped solely with a PCIe connected SSD?
