2017 iMac 27" Fusion Drive question

I just got a new (2017) 27" iMac with a 2TB Fusion drive. I can't find any evidence of there being an SSD component to the drive. All I see is the rotational HDD. Do I have an SSD component and how do I access and manage it?

Funny, my spouse's late 2015 also did not show the SSD portion in "SATA/SATA express" under "About this Mac"


If you really want to know the SSD part/size, you can access via "terminal" by typing "diskutil list"


Disk0 will be the fusion drive -- contains disk1 as the SSD and disk2 as the 2T mechanical drive.
