Just purchased a 2nd hand 2019 iMac (21.5 model - 3.2 i7). It was advertised as having a 1TB SSD, but upon receiving it and firing it up, it appears to have a 1TB SSD AND a 1TB HDD (see screenshot). Has anybody seen this configuration before? Would it originally have been set up as a Fusion Drive? I can't find anything online that matches this set up. Just wondering what the best way would be to set this up?
