The diskutil command in Terminal gives you a wealth of detail, which you seldom need in day-to-day work, intended for when you need to refer to volumes using their Unix names, such as disk3s2.It doesn’t give full details, or even show all available volumes, though.

What we saw in the Finder and in Disk Utility was reasonably close to what we needed to use, and wasn’t too far from what you’d find using the diskutil command in Terminal. Click on it, then quit Disk Utility.Until Apple introduced APFS, the normal structure of our Mac’s disks and volumes was relatively simple.
