PCI-E x1 NVME Adaptor

[ᶻ𝗓𐰁]

I have 2 PCI-E x1 slots, can I just plug an adaptor into both slots and use them both for drives?

Do I need to do anything with my power supply or will they have the power they need from the mobo?

Will they stop any sata ports from working?

Will they just show up automatically when I plug them in?

Anything else I need to know?

No power required

Won affect sata ports

Should show fine. If not they will have a driver you can download

Thanks, how can I find out if my mobo will allow the OS to boot from the x1? I'd like a larger NVME in my M2 but I don't really want to reinstall my OS if I can just switch the slots and have it boot up right away.

if the mobo has a m.2 nvme slot, boot from that
and use the pci-e adapters for secondary/slave drives

pci-e x1 will be limited to x1 speeds, most newer nvme slots are x4

Okay, thanks. Will PCI-E 3.0 x1 give me about 1gb speeds?

Refer to the manual because if you use M.2 it could turn one or both of those off depending on how that board was manufactured so it is best to look in the manual if you are using any M.2 ssd drives in conjunction with the PCIe x1 adapter.

My PCIe x8 turns off my PCIe x1 and PCIe x16 turns off the other; although, my board is far older x370 but it is by the branding on how they are routing these things.

The manual says it switches off the Sata 1 slot, it doesn't mention the PCIe x1 slots.

what mobo, brand/model?

the manual will say how its pci-e lanes are divided
but the cpu/mobo/chipset can reassign lanes as needed

thats a super legacy board
rear serial rs232 port (and header for com 2), vga, ps2 k/m ports, even a parallel (printer) port header on the board and a pci slot (pre pci-e)

it looks to support booting from pci/pci-e to sata or pata (ide) adapters
i doubt it would boot from pci-e to nvme
you can try and see if it sees the nvme drive im bios and can boot from it

I'll just reinstall on the new NVMe in the M2, I'm mostly concerned about the x1 adaptors working. Can I use that PCI for storage?

[_I_]

yes, windows will have drivers to use them as storage even if bios does not see the drives

If you mean the actual PCI slot and not the PCIe slot; no you won’t be able to use the PCI slot for storage like that. You could get a PCI SATA HBA to add more SATA ports via that PCI slot but most PCI storage controllers are going to be for old IDE / PATA drives.

Okay thanks, yeah I just looked it up, seems it has no use for someone like me.

I got an Nvme PCIe adapter.

It was a disaster. I don't know if there was a firmware issue or a wrong bios setting, but there was frequent read-write failures and total system lockups until I took it out and moved the drive to the normal motherboard M.2 slot.

What Motherboard do you have?
How many NVME SSDs you need room for?
