Quad NVMe PCIe Adapter, RIITOP 4-Port NVMe to PCI-e 4.0/3.0 x16 Expand Controller Card with Heatsink for 2280/2260/2242/2230 M.2 NVMe SSD (PCI-e Bifurcation Required)

There are no directions with this thing. Not super hard to figure out but there is a larger case screw and what would be a mobo stand off that I can't see why I would use, I think they also make one of these with a fan, maybe they just include the same screws with them all. If you are using full size 2280 drive then the standoffs are built into the PCB however if your using smaller ones they are not. I want to explain this cause I saw some ppl complain that it was unclear. In the bag you get 4 normal size screws which are used to hold the heatsink on and then 8 smaller screws which are used to hold the nvme drive down. Now if you're wondering why 8 screws when only 4 nvme drives that's where the 4 little silver stand offs come in. The standoffs have a flat side and a concave side. If you're using any other size other than 2280 then put the concave side down on the PCB and put one of those little screws in through the back to hold it to the card. Then put ur nvme drive in and put another small screen through the top to hold the drive down. Hope that helps. Also I need bifurcation support on ur mobo, if you don't have it will not work. Do ur research not the products fault.

Working in Dell R630. This is WIn10 screen cap, works in Linux also. I only tested this for storage notOS/BOOT drive. I cant find it anywhere in the BIOS to set it up as RAID, i had to boot Linux from flash card after i loaded it on there.I used 4 of the cheapest drives i could find so that speed is right about on par for Windows R-0There is probably a correct way to set this up, like pointing to the UEFI boot loader but i just bought this 630 yesterday and don't know anything about it yet.

I didn't get any problem with this product.

My B550 A Pro (MS7c65) mother board claims to support 4x4x4x PCIE - the card is recognized by windows device driver as a standard nvm express controller but no SSDs are discovered.

no call to tech support needed, did what is supposed to do

It works good

Works great.. very reasonable cost.The included heatsink is why I chose this one over many others.I have tried (and returned) 5-10 other cards, and this one is a great budget option. The heatsink is super-important for NVMe cards, so any choice you make should include it.. performance will suffer without...More expensive options for your Mac Pro are the RIITOP dual card (that's a switching card) and the Ableconn (also switching), but both are 10-15x's the cost of this one, so the additional cost to just get 2 card mounts seems a bit excessive.. OWC makes a super-fast card, but it's nearly $500...

My ASUS B550-PLUS supports bifurcation. Could not get the system to recognize anything with this card.
