Zunate M.2 NVME to PCIe X16 Adapter, M Key Hard Drive Converter Reader Expansion Card, 4 Port NVMe to PCI-e Host Controller Expansion Card (ph44)

It does work on Dell Precision T5810 which support bifurcation natively. Perfect!

Only sees one drive. Found out too late that none of my machines support bifurcation.

The card works well and is of good build quality. Make SURE the slot you are putting it in is a 16x connector both physically and electrically. You must make sure your CPU has enough pcie lanes available, and that the motherboard supports pcie bifurcation. If any of these requirements aren't met, you will likely only see one drive connected. For example, I have 3 pcie 16x slots and 3 pcie 1x slots. The top two pcie 16x slots are 16x/0x or 8x/8x mode. The bottom 16x slot is actually just a pcie 4x, unless any of the 1x slots is populated. If any 1x slot is populated, then the button 16x slot operates in 1x mode. So my motherboard could technically support this card properly if I move my graphics card to the effectively 4x slot on the bottom and enable 4x/4x/4x/4x bifurcation on the top pcie 16x slot. I tested this, and it does indeed work, but I take a huge performance penalty on the GPU. I'll be saving this card for the future for when I build a server.

I'm using this in a server board with an EPYC which has plenty of PCI-E lanes, and this works beautifully. You might want to have cooling on your individual NVMe drives that you mount, but it works exactly as you would think it does. I have it in a case with high airflow and heatsinks on the drives. Haven't had a drive drop yet from heat.

Solo funciona una ranura de las 4

Works PERFECTLY but there’s. catch: you need a motherboard that supports “bifurcation”, a 16x PCIE slot split into 4 4x “slots” so that ALL 4 drives will be seen. Typically, workstation and server motherboards support that feature… Caveat Emptur…

My computer supports PCIe bifurcation, so there's no reason for it not to work. In any case, even without PCIe bifurcation, the computer should detect the first drive correctly, which isn't the case here. Seller is of no help, so I'll simply return the product and spend my money on a different brand

Très bien, 👍

Awesome, i recommend.

With PCIe bifurcation set to x4x4x4x4 I’m experiencing multiple drive drop outs per day, platform is ASUS x299 gaming, i9-9920x, 4x Crucial P5 Plus 2TB
