Any adapter? Or do you specifically mean a x8 pci-e3.0 adapter plugged into an x8 pci-e2.0 slot?
That is a cool suggestion but I am not looking to top out the machine or buy more hardware than is necessary. The money will be spent on a 1TB nvme drive for a newer system, period. I am simply wishing to be able to do something with a soon-to-be-sitting-on-shelf smaller/older nvme drive. I do not want to buy hardware for this old PC, if I can avoid it. Switch adapters are too pricey but a regular $20 adapter is an acceptable solution. Later, when I bother to make it bootable, it will increase the speed overall and avoid hardware sitting, not being used. RAID is fun but it's also a pain in the ass and adds overhead to the system. 6 drives for a 'system drive' is a problem waiting to happen, in my opinion. I'd sooner buy the switch adapter at that point
I really can't believe only one person responded with anything useful. I went out of my way to be as detailed and accurate as possible in what I wanted to know and yet most assumed or interpreted my words to mean something else. A lot of you should go back to grade school and relearn how to read. All I wanted to know is if I placed a x8 pci-e3.0 nvme adapter card into an x8 pci-e2.0 slot, if I would be able to achieve x4 pci-e3.0 speeds, as that is what the nvme drive is. I am led to believe I would need a switch adapter for this but I wanted to be sure. I am not throwing out a perfectly good system that performs well; I am not buying hard drives for this old system; I am not trying to get max speed from anything. Since I am going to replace a 250GB nvme drive with a 1TB nvme drive, I figured I could cheaply throw it into the old PC.
You said it yourself "The pci-e slots are revision 2.0,"
So
PCIe Rev 2 = 500MB/s x 8 = 4000 MB/s
PCIe Rev 3 = 985MB/s x 4 = 3938 MB/s
Theorically they are pretty near
But it does not mean that your MB is going to treat it like that...
Did I ask you if I should pursue something, or did I ask a specific question regrading pci-e? Is your head so big that you think you know what is best for me through inference of the question(s) that I ask? So, instead of answering the OP you decided to "assume" and not answer it at all, and go off on down your own path? Who said anything about being able to boot from it? I specifically stated I was not interested in booting from this drive. As to why that is, is nobody's business; that question was not on the table. Why do you assume anything? Why not stick precisely to what was asked or say nothing at all?
So you admit to understanding what information I was seeking to know but you purposely decided to tell me something else because you "assumed"? Were this my website, for that act and admission, you'd be banned. Did I ask for someone to assume and give me an answer based on assumption, or could it be I was hoping someone actually knew from real world experience?
If respondents can't stay on point, only answering what was asked and nothing more, could it be they should stay silent instead of polluting the chat? I wish you and others luck carrying around those big heads, as that must be hard on the neck.
I do expect narrow precise answers as that is the point of forums...to stick precisely to what the OP is about. Not assume or do as you want. I am disappointed and annoyed. Yet again, you admit to purposefully detracting from the OP.
There is nothing wrong with providing extra information or asking questions surround the OP, provided one actually answers the question originally asked.

Exactly. Right. That is what I am here to find out. Will a regular adapter do this or would I need a switch adapter?

You mean the actual m.2 port would have to be x8, on the adapter card? I was wondering this too. There is no such thing as a x8 m.2 drive that I am aware of.
I think a regular adapter will run 4 x 500MB/s on PCIe rev 2
I don't know what is that Switch adapter... But, 1 Nvme drive will use 4 lanes no more, you need to add more drives to get more lanes active that's why a 16x nvme adapter has provision for 4 nvme drives 8x for two... They must be all installed to use the whole bandwidth of the slot.
This will be much faster than one SSd alone. But you might end up forced to use one to boot anyway.
Yeah the actual m.2 port should be x8 for the ssd to run at full speed. It does not exist I know it was an example to explain what should be had for these 4 GB / s in pci express 2.0.
There are pci express 16x(can be plugged into X4 and X8 slot) 4.0 x4 adapter cards with only one m.2 slot on the card. As your generation is 2.0, everything will pass in this generation, the m.2 slot on the card too. You will then only have 2,000 GB/s theoretical in write/read.

edit: The adapter card is 16X physical size, 4X bandwidth. It's not 16X bandwidth like I thought.
