Installed on my pc for 2- 4tb cards and it worked as intended. I would recommend

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.

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.

I was able to get PCIe 4.0 x4 speeds with both of my drives and was able to boot from it (X570). I think the M.2 slots are tad too close to each other and most heatsinks will probably conflict with each other when using 2 of them. If your using 1 proper heatsink and a 1 rubber band heatsink, you'll probably be fine. The M.2 stand cuts for the M.2 to attach have a large gap, which means it'll move slightly up and down when fully screwed down. Some heatsinks (Like the Sabrent Rocket) don't have this movement problem. I wish Glotrends would make a proper heatsink version of this card like what they do with their 1 drive cards. I do like how it comes with a low profile bracket, which is perfect for cases like that one Lian case with the vertical GPU. It does the job and its a good price. Will update if I have any problems, I currently don't see any in Event Viewer.

TLDR: It does what it says it will - however, it is not designed to operate at pcie 4. It will function, but if you do not want to have issues or operation errors when trying operate at pcie4 speeds, go look elsewhere. If you are dead set on this one, only use this at PCIe 3 speeds or lower. Longer version: I purchased this for a custom 2u server build out thinking this would hold true to the pcie4 claims. I purchased an ASRock Rack B650D4U, 96GB of ECC DDR5, and 5x Micron 7450 Pro pcie 4 M.2 NVMe SSDs. Enabled a setting in bios to verify no PCIe errors were occurring, checked to make sure all the drives were showing up, and booted up a copy of Proxmox. Right after the kernel loaded, the screen was full of PCIe errors whizzing by. The Micron SSDs mentioned earlier that were attached to glotrends card were sitting idle, empty, and hadn't been formatted yet, were throwing so many errors it was hard to read what was going on. Go back into bios and force the speed for the SSD's attached to operate at PCIe 3 and all of the errors are gone. I got what I paid for - cheap and counting on you not to verify claims.

A good value. There are rival options that cost many times more and deliver the same performance. This only works with systems that support PCIe bifurcation. Check system BIOS before buying. It's also compatible with heat sinks. Pros Does what it claims. A good product, especially for the price. Cons The brass standoffs need to be installed after the drive in placed in its socket. Then the standoffs need to be screwed in from the bottom. Would be nice if it included heat sinks, but at the price, it's reasonable that it doesn't.

I was unable to take full advantage of this card because of my motherboard. I can only bifurcate x4x4x8. If you want to use all of them, then you need x4x4x4x4. I knew that going in though, and I'm super happy to have three more NVMe cards on my motherboard.

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.

Doesn't work well with X670E-E MB. Don't waste your time playing with bifurcation modes or searching for a solution, you'll get only one m.2 working at best.

Works perfectly - the only catch is that you have to understand what this card will or will not do. It does not have a chipset which handles the bifurcation - it literally routes PCIe lanes 0-3 to the first m.2, lanes 4-7 to the second slot and so on. So the motherboard, chipset and CPU need to support x4/x4/x4/x4 bifurcation before you could add four m.2 drives - and that is actually pretty uncommon on modern boards. For example intel 13th and 14th gen CPUS only support x8/x8 bifurcation on the primary (i.e. connected to the CPU) PCIe x16 interface. 15th gen supports x8/x4/x4 which is a little more flexible. So you need to know how many physical PCIe lanes a slot has, and whether it supports bifurcation to know whether this will be useful for you. x4/x4/x4/x4 - you can install four m.2 drives, x8/x4/x4 and you can install three, x8/x8 gets you two and no bifurcation support means you can only install a single drive.

Works perfect with the low profile adapter in my Power Edge R730! Be sure your motherboard or server supports Bifurcation as the listing says this unit does NOT bifurcate on the card.

Works like a charm if your motherboard and cpu have enough for it since each drive needs 4 data PCIe lanes.

Good product. Great for multiple drives in a compact space Installed it in an old dell r730. Watch out cause your system needs to support bifurcation otherwise only 1 drive will be detected. Not all systems / bios do support this. Performance wise i can't complain and each M.2 disk in it is fast. Also the controller is cooled. I've added extra heat fans on each m.2 but that will depend on your system if there is enough space. However i was not a fan of the fixing mechanism. even though the m.2 are fixed they are to loose to my linking with this system.
