GLOTRENDS PA41 Quad M.2 NVMe to PCIe 4.0 X16 Adapter Without PCIe Bifurcation Function, Support 22110/2280/2260/2242/2230 Size (PCIe Bifurcation Motherboard is Required)

The media could not be loaded. 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.

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.

I purchased this a while back and was very confused why I wasn't getting the speeds I was expecting like the listing claims. I initially thought it was due to overhead of ZFS, so I researched more. Then I took a closer look at the board... What is under that heatsink? So here we go...Although this does the job of bifurcation, it doesn't technically require full bifurcation support on your system.... Because it's not a bifurcation card, it's rather a splitter card. For it to be an actual bifurcation card, it has to be entirely passive. You see, it has a sneaky little PCIE switch chip that has a PCIE Gen2 x1 upstream and splits it into 4 PCIE Gen2x1, essentially only giving an theoretical maximum of 500MB/s. You can look up the chip from asmedia: "ASM1184E" to find out more.And this is where this gets a little squirrely... The seller states in the listing "~32GBbps (PCIe 4.0 X16)". The listing claims you can get PCIe Gen4x16 bandwidth which is entirely false. If this was an actual bifurcation card, meaning it should be passive, then you wouldn't need a PCIe switch chip. I find the product listing very deceiving.

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.

The board is great, affordable and easy to use and works well. It would probably be a good idea as other have mentioned to use single sided M.2 drives as there may be clearance issues for double sided drives due to the design of the board.Like some others have experienced, my order was missing the stand offs and screws that were supposed to be preinstalled on the board. I contacted the Glotrends and they shipped the missing screws the next day. It took a while but I eventually got them and everything works fine. They were very responsive and stand behind their product and I commend them for that.In the end, the board is working great and I am satisfied with my purchase.

Works as spec it, fast delivery, A+++ seller love the item. Thank you

I LOVE FACT IT HAS ROOM FOR 4 NVME DRIVES ON 1 BOARD. THATS AMAZING.I PUT MINE IN A MACHINST MOTHERBOARD THAT ONLY HAD ROOM FOR AN OLDSTYLE M.2 SATA DRIVE. I TOOK THAT OUT AND PUT IN THE NEW AND ITS BOOTEDUP IMMEDIATELY. THE DRIVE I PUT ON IT WAS AN WINDOWS 10 FORMATTED DRIVE.I BUILD PC'S FOR MY FREINDS AND CHURCH, AND I WILL TRY IT ON 3 OTHER MACHINESI OWN NOW.... WOW.

I bought two of these cards and both didn't have the screws and screwposts at 2280 advertised in the picture. They only have 22110 screwposts and yet are missing the screws for it. Can't even find 22110 drives and got it for the 2280 drives.
