and primary partition and primary partition for disk 1 [D:].

When doing the clean install, select the custom install option. The next screen will show a list of disks and partitions. Delete all the partitions on disk 0 until it is nothing but unallocated space. Highlight the unallocated space and click next to let Windows setup the drive the way that it wants to. Just be careful to not delete you data partition on disk 1!

If you clean install another option that is timely is BIOS/MBR versus UEFI/GPT

This is key. FWIW I just installed W10 on a new SSD (using MBR) expecting it would create 4 partitions as shown in one those links but it ended up having no partitions (I intended to use the entire drive rather than separate partitions) BUT w/o the 4 partition scheme - as I "think" would be created using GPT &/or UEFI(??) - my understanding is you lose the benefits of recovery options & less chance of things getting corrupted.

It would be very interesting to see a screenshot of your disk management.

What disk management in W10 shows (in W7 Local Disk 1 is the C: OS SSD & the drive letter assignments are different......if that is relevant!)

You have 1 partition on the new SSD, C: drive which contains the OS. The system partition the computer boots from is on the 60 GB SSD. Your computer boots from the 60 GB SSD and then loads the OS from the new about 480 GB SSD. Newer installations of Windows 10 do not create a separate recovery partition (at least on MBR drives). The recovery function is contained in a recovery folder on C: drive. You can see where your recovery functions are loaded from, and if enabled or not, by running:
reagentc /info

I see. reagentc / info shows: "Windows RE status: Disabled" on my system. I don't think I disabled it since installation.

When performing windows upgrades windows can install on multiple drives.
Once Windows is on only one drive you can detach cables or remove drives.
