Will a PCIe 3.0 Nvme work on a PCIe 4.0 motherboard?

I have a PCIe 3.0 Corsair MP510 at the moment on a MSI Pro Carbon AC B450 motherboard.

Im looking to upgrade my rig, but still want to use this SSD. If I was to get an x570 board that has PCIe 4.0, will this nvme drive still work with it?

I know the speeds will still be PCIe 3.0 speeds, but just wondering if its backwards/forwards compatible.

Also by this same logic, will this nvme work on a board that comes with PCIe 2.0? I assume the answer is most likely no for this one

As said works fine
Got 2x 960gb mp510 on x570 board

Pci~e 2.0?
Would that even have the necessary connector

Thanks both for your help in answering!

Also, I was wondering about PCIe 2.0 because if im on a PCIe 4.0 board, I may hold onto it for a while and then buy a PCIe 5.0 nvme once it gets released. So naturally im curious if i can just buy a newer nvme and place it in a older board, and just see if it will work compatibility wise

It's an M2 drive
Did pci~e 2.0 boards even have M2 slots
I know graphics cards are backwards compatible

missed the m.2 part. Thought it was a straight up pcie slot connector drive.

But you can get pcie riser cards with m.2 slots to fit m.2 form drives. I am actually looking to do the very same thing. I am just concerned about bootability of doing it thing way.

Got a riser card
Boots fine on newer boards
But on older boards it may not
Think saw some one say earlier could boot it on z97
But it's something you would need to check for your particular board model

My board supports nvme but I am not sure it supports riser card and boot. I will have to order and see

It should support the riser/pcie card if supports nvme would think
Boot able is another matter
Which board?
Think I have done it on a z170
But can't remember the board I had previous to that one
Only issue I had with the riser card was after a while the adhesive heatsink fell off the M2
Thermal adhesive would be better though more permanent
A screwed on heatsink would be what I would look for next time on the riser card

M.2 is just physical/connector form factor.
It doesn't affect to signal using it.

PCI express could be used even over SATA like cables for having drive in 2.5" physical form factor:

That would actually allow fitting more NVMe drives than it's possible to fit M.2 slots on mobo.
(and higher capacity drives than it's possible to fit into M.2 card)

That's very old
We had sata express ports on some boards
It never caught on
That article says 2000MBs
We are already way beyond that with M2 drives
