I'm looking to buy a used X1 Yoga 1st Gen. In looking at the spec (here, under Specifications tab), under storage I see
Storage Some: M.2 SSD / SATA 6.0Gb/s Some: M.2 SSD / PCIe NVMe, PCIe 3.0 x 4, 32Gb/s
Indeed, when you look at the 50-odd US models of this unit, you see that some come with M.2 SATA 3 drives and others with M.2 PCIe/NVMe drives. If, say, I buy a unit with a SATA 3 drive, then want to upgrade, must I buy a SATA 3 drive, or can I choose either SATA or NVMe/PCIe? And on the off-chance I live large and buy a 2nd Gen, does the same answer apply? (given that the spec sheet says exactly the same thing in the Storage sub-section.) Thank you.

Its motherboard supports both Sata3 and NVMe interface in circuit.
but most models sold in the US are factory installed with NVMe ssds.
only those very cheap models (with low resolution LCD and sold with
highly discount prices) are factory installed with Sata3 ssds. So if you
buy a used one, your chance to see a Sata3 ssd is very low.
X1Y gen1 to gen3 are almost identical. The circuit board are almost
the same, all sockets, screw holes, etc. are the same. As far as I know,
besides the USB-C functionality, the other difference is lenovo NFC daughter
card doesn't work for X1Y1 , but work for X1Y2 and X1Y3---although X1Y1
does have the socket and electric wires for NFC daughter card.
My personal opinion:
It looks that X1Y1 was pushed into the market in a very hurry way. the
design is almost premature, It has many small problems, for example,
wwan card needs 30 second to be ready everytime wakes up from sleep.
It is very annoying. and many small functions are not ready (although
it does have all the wires/sockets/components on the mother board),
so lenovo fixed these things slowly in X1Y2 and X1Y3.

Actually, it looks like, of the 51 U.S. models of the Gen 1 listed on Lenovo's site, 24 state explicitly that they shipped with SATA 3 drives, 10 with PCIe/NVMe, and 16 with an unspecified M.2 SSD. Of that 24, 9 have a WQHD display, 9 (some w/ WQHD, some not) have i7 CPU's and a 10th offers 16GB of memory. So I wouldn't say SATA3's showed up only on "very cheap" models.
In any case, thank you for taking the time to respond in detail. I also appreciate your opinion about Y1 reliability. Problems seem to be the norm for pretty much 1st-gen anything.

The models you listed are for 3rd party retail company resell or direct business orders. If you as a consumer placed the order from lenovo website, the model number would be 20FQCTO1WW, there was no option to choose a SATA3 SSD. NVMe was the only option.
As I remember, when X1Y1 was out, the NVMe with OPAL2 encryption was not ready, probably that's the reason there are so many company models with SATA3 SSD.
