Note: My motherboard does not have bifurcation

 

I wanted to upgrade my flash scratch disks and am becoming weary of commercial M.2.  I would like to use datacenter grade U.2 flash drives.  I however do not have the appropriate ports on my motherboard.

 

I wanted to use a Gen4 PCI-E fullsize card slot, but I'm unsure if my motherboard would see all 4x devices if I used something like this:

amazon link /  ebay link / aliexpress link

 

1. I'm guessing by split they mean 'requires a motherboard with bifurcation'?
2. If they don't work, does anyone know of a device that would work to let me use a PCI-E Gen4 slot for 4x U2 without needing to sell a kidney?

Without bifurcation it will require a PLX chip, I doubt you will be able to find anything below $100.

1) Yes

2) something like this https://www.broadcom.com/products/storage/host-bus-adapters/sas-nvme-9600w-16e about 500 Dollar ish

 

and you can look here for PLX chips https://c-payne.com/index.php?route=product/product&path=66&product_id=86

Darn.  Holy smokes, broadcom one is 700+ euros 😶

 

This one looks a bit more economical:

but i'm guessing there's a catch (PCIE3.. slow?)?

if you consider theoretical 15,5 GByte/s slow then yes
