Now I wonder, compared with other CBM drives, is there a rarity ranking?

I am thinking some of the rarest 8-bit CBM drives manufactured by CBM are (in no particular order and without looking on the internet for the answer)

8080 (dual 8" IEEE drive) 1540 1551 9060 9090 1570 (where these actually sold) The drive that came with the C-65

am I missing anything rarer than these?

Next would be 2040 (IEEE) 4040 (IEEE) 8250 (IEEE) SFD-1001

I would add 8050 after SFD-1001

You said 8080 -- is that part of the 8060 series? 8060, 8061, 8062, 8280 (I've only seen pictures)

Any third party drives make your list? MSD MSD-2 Indus GT

I was leaving out 3rd party just to manage the scope. The 8080 is an 8050 with 8" drives. I never heard of 8x6x drives so Indint know. The most common IEEE drive by far is the 8050, followed by sfd-1001, 2031, 2040. 4040's and 8250's are a little rarer as I have found.
