10Gtek Dual M.2 NVMe SSD Adapter Card - PCIe 3.0 x8 Slot (M-Key), Supports 2X NVMe Drives via Bifurcation | Requires BIOS Split Support | High-Speed Storage Expansion for Desktop PCs

I don't usually write reviews for a product unless there is something dangerously wrong with it that people need to know about, but I had to take a chance on this item because it is a new listing without many reviews, so I wanted to share my thoughts.Short version: there is nothing wrong with this item and it works exactly as I would expect it to.I purchased this to boot from NVMe disks on an HP Z440 (intel C612 based system with a v3 Haswell Xeon CPU). I changed the setting for bifurcation in BIOS from x8 to x4/x4 on the only PCIe 3.0 x8 slot on the board and it recognized and booted from the installed 500GB SN570 without any further fiddling around.I found the item itself to be properly packaged and very sharp looking, which is to say that there were no signs of sloppy manufacturing, badly stamped or machined brackets, shoddy solder joints, etc. The packaging was mundane but adequate to protect the item in shipping.What else is there to say? It is a competently manufactured item, which does the job it claims, with no fuss - for about 20-30% less than the cost of other no-name competitors, or less than half of the name-brand alternatives. Buy one - find out for yourself!Please do keep in mind that it will not support dual (or quad for that matter) disks unless your motherboard properly supports bifurcation, and you'll need a free PCIe 3.0 slot (or higher) to achieve the maximum rated speeds.

I installed two Samsung 990 4TB NVME M.2 on this card. They work beautifully on a Proxmox running on a SuperMicro server hardware.Had to experiment to find the right BIOS bifurcation setting. Turned out to be 4x4x4.Do note that this card will not work for you if you do not have bifurcation available.

Works as expected.

Works great in my Dell Precision T7920. However, need to know, that bifurcation doesn't work in all PCIe slots, only in PCIe x16.

Review based on the two device version. I liked this one well enough that I also purchased the single module version.It seems to be a well made, functional adapter at a reasonable price. It is easy to use except for attaching the hold-down screw and brass "nut". These are very small and require good close-up vision and some manual dexterity to install. Note that the brass nut has a slot which engages the edge of the M.2 module. The slot is offset. When installing, the thicker part of the "nut" goes against the PCB. This adapter does not have a heatsink, and usually a heatsink is not required. It actually makes it easier to use as there are no additional steps to removing and replacing a heat sink. In case one is going to install a 2T M.2 module, and drive it hard, then the heatsink models might have an advantage.It should be repeated that not all PCs will work with the two or four module versions of this ( or any other ) adapter. The PC needs to support PCIe bifurcation, and there needs to be enough PCIe lanes for the drives that you are adding. Four more lanes per drive. Usually only the workstation class of PCs or servers have the slots to work with these at the same time as a graphics card. The symptom of not supporting bifurcation ( or the bifurcation feature not being configured in the BIOS ) is that only the first M.2 is recognized by the system

Worked when I enabled RAID Mode for the PCI slot that the adapter was plugged into. I am Not running a RAID, but it works. My MB is a ASUS X-470 PRO with updated BIOS.

Bifurcation device works perfectly. I have two of these cards in two separate PCs and it allowed me to add two (2) M.2 drives to each slot for each PC.

Ordered this to add dual high speed NVMe storage to a HP DL380 g10 server, which supports pcie bifurcation, and the system picked up my two drives on the first try and has been humming along for a few months now.Be aware this doesn't support 22110 size SSDs directly. Ask me how I know, haha. I was able to install the too long dries but there is no mount point to screw them down so I ended up fastening them with zip ties. I don't think any consumer drives are this size, usually just a few of the enterprise models.
