Why does my 2019 27" iMac have identical listings in Storage for both a 1.03 TB SATA Disk and 1.03 TB Solid State PCI Express Drive?
My 2019 27" iMac has become very slow, particularly when attempting to switch between different user accounts on the computer. In attempting to diagnose the issue, I noticed as seen in the screen shot attached here that in the Storage settings it shows both a 1.03 TB SATA Disk and 1.03 TB Solid State PCI Express Drive with identical storage usage.
What does this mean? Is it some sort of configuration error? Could it be responsible for the computer's over-all slowness? Thank you for any help...
iMac 21.5″
