Review: Works as advertised - Worked as advertised. Moved my GPU to the second slot in my ASUS ROG X870-A Gaming Wifi board and put this card into the primary PCIE 5.0 slot and set bios to bifurcate x4/x4/x4/x4. This freed up the other 3 NVMe slots on the mobo. Immediately recognized the three NVMe drives I mounted and they were running full x4 speed. Just remember that in order for this to work, your motherboard needs to support bifurcation.
Review: Much smaller than the alternative - Took a while to find this, but someone finally made one! I'd previously been using Asus's 4-drive card, which is absolutely massive. Unfortunately, that one cuts down on the case selection due to its massive size, and I've been wanting to move my server to a smaller, rack-mount chassis. I've included a picture for comparison. This seems to work great. Note that you will need to have a motherboard that supports bifurcation (x4x4x4x4, if you want to use all 4 slots). One thing to keep in mind is that if you are using NVMEs with chips on the back <22110 in length (i.e. 2280 and shorter), there might be interference with the screw for the drive on the other side. I've included a picture showing the screw sticking out the back. Note that I don't know how common NVME drives with chips on the back are. Fortunately, only 2 of my NVME drives are double-sided, and they are 22110 in length, so I was able to install them without an issue by putting them on opposite sides of the card (rather than next to each other). This is because the 22110 posts are permanently attached to the card, so don't require a screw on the other side. Also, for clarification of how 2280 and smaller drives are installed, see attached pictures - it took me longer than I'd care to admit to figure this out.

## Features

- Dual M.2 NVMe to PCIe 4.0 X8 Adapter: By installing 2 M.2 NVMe SSDs (Support 22110/2280/2260/2242/2230 M.2 NVMe SSD) on this PCIe 4.0 X8 adapter, your computer will be able to access 2 M.2 NVMe SSDs at the same time
- Hardware Platform: Support Soft RAID in Intel/AMD platform, not support Mac Pro 5.1 (Note: To set up Intel's RAID-on-CPU (VROC), you need to purchase your license)
- Set the PCIe Bifurcation mode of the corresponding PCIe slot in the BIOS, support X4X4X4X4 or X4X4X8 or Hyper M.2 X16 mode (Note: Can not support X8X4X4 mode)
- Important: Because this adapter does not support PCIe Bifurcation, it requires a motherboard that supports PCIe Bifurcation. Otherwise, only the NVMe-1 port can recognize the NVMe SSD. Before purchasing, please check the PCIe expansion slot part of the motherboard manual on the motherboard manufacturer's website, or consult us directly
- To reach PCIe 4.0 X4 (64Gbps) full speed, the CPU and motherboard PCIe slot and PCIe M.2 SSD should all be PCIe 4.0 features (Note: PCIe 4.0 is not supported on Intel CPUs below 11th generation)
- Support OS Booting: Reinstall the OS, and set up BIOS/UEFI boot from this M.2 NVMe SSD (Note: Some motherboards are too old to support OS booting. In this case, M.2 NVMe SSDs can be used as storage disks)
- OS compatibility: Plug-and-play in Windows 11/10/8/Linux/Mac OS (Note: Not support Windows 7). The new M.2 NVMe SSD needs to be initialized and formatted before it can be recognized by the computer host.

### ⭐⭐⭐⭐⭐ Works as advertised

### ⭐⭐⭐⭐⭐ Much smaller than the alternative

Unfortunately, that one cuts down on the case selection due to its massive size, and I've been wanting to move my server to a smaller, rack-mount chassis. I've included a picture for comparison.

### ⭐⭐⭐⭐⭐ It works - requires bifurcation motherboard
*by D***A on September 6, 2023*

Not sure if I spelled that right, bifurcation. This card does not do its own bifurcation. If your motherboard dose then make sure it can bifurcate by 4, the slot you put it into. I would have had to use this in the first x16 slot, which my GPU occupies, in order to get x4, but I couldn't fit the GPU into the second slot so I had to buy another .. well, 2 of these that actually DO bifurcation on the adapter itself. I ended up not using this, I'll figure out a use for it in the future, because my second slot cannot X4 bifurcate, only x2, so watch out for that. The first slot can do x4 but the second slot on the mobo is only x2, this is something I didn't expect to run into and I didn't find any information about it so you have that info here now. If you want to make sure all of your nvme show up in your OS, get a board that does the bifurcation on-board, not forcing the motherboard to do it as a feature. You'll be glad you spend the extra money and it will cost quite a bit more for that. Also, what I did was get pcie gen 3 cards with 2x nvme slots on each. I have pcie gen 4 but the way I set this up the nvme are just a tad bit faster than my gen 4 nvme I have on board. I did raid0 on the entire set which grants me a bit over full speed of my gen 4 drives. This was a cheaper alternative since I am doing raid0 but if you're not doing raid0 then it will be much slower if getting gen 4. Safest bet is gen 4 all the way through, of course.
