I have a few of the gigabyte aorus gen4 aic. these cards let you put 4 x m.2 nvme gen4 ssds into a single x16 pci gen4 slot. these cards are pretty large and will only fit in 3 of the 5 pci slots in one of my servers. I have an extra 2 x16 pcie gen4 slots but they will only accept HL/LP cards. the server will do bifurcation so I don't need that feature on the card. I would be ok with at least 2 m.2 ssds per card if the card would fit. I have seen some cards that are low profile and half length that have 2 m.2 ssds on each side. However, these cards were pci gen3.
Thanks for any suggestions,
jp

Amazon.com: JEYI M.2 X16 PCIe 4.0 X4 Expansion Card, Supports 4 NVMe M.2 2280 up to 256Gbps, Support Bifurcation Raid : Electronics

I have one of these that I am using for PCIe gen3 and only using one of the slots right now. It should work with the other 3 slots but haven't tried it yet.
Thanks for the tip. I ordered 4 of these last night from China but the will take about a month to get here. Saw your post this morning and ordered them from Amazon. Should get here tomorrow. Thanks again!

received it today and it worked without issue. I used 4 x seagate firecuda 530 2TB m.2 drives. It was just short enough to fit into one of my servers that I needed this card for. I needed to fit it into riser #2 in a dell r7525. Luckily it fit without even a mm to spare!

I'm glad it worked out and you verified that it should work for me once I need to use the other slots.

received it today and it worked without issue. (JEYI M.2 x16 PCIe 4.0 x4 Expansion Card)
I have the Gen3 "version" of that card, and I'm curious ...
If possible, can you read the part # of the Clock_Buffer chip (rectangular chip between the bracket and the M2 slots). Thanks
[On my Gen3, it is PI6C 20400BLE.]

Interesting. (The LE suffix is just the packaging/form-factor, but) the absence/presence of the B does identify two different chips, PI6C20400_datasheet and PI6C20400B_datasheet.
[Above links are to original/first-edition datasheets (Mar'13 and Jan'17). Latest revisions (Jan'21) are 00 and 00B.]

The important thing is that both our cards work as we expected.

This LP M.2 to PCIe 4.0 card seems only take 2280 NVMe. It means you can mostly use consumer or prosumer grade NVMe with no PLP. I have been looking for a Gen 4 one that can support 22110 NVMe (with PLP). Hard to get a 2280 M.2 NVMe that is DC or enterprise grade with PLP. Though you can easily get 2280 M.2 SATA ssd with PLP

If I needed Gen4, I'd buy THIS one ($45). [EDIT] Holy Guacamole! Check out THIS OTHER one! On SALE until 12Mar22:0300 ET for $26! Has a fan; that makes it 4cm longer. But I'm sure you could just cut off the fan if you wanted/needed to.[/EDIT]

Thanks. The Two-sided with fan can support for (4) M.2, looks interesting. $26 price is quite good. But has anyone actually used or tested it? Would get one if it is available over amazon or else than can ship fast. It ships from China or Europe probably will take over 2 weeks to a month

@dbTH , the real question is: Are there any Gen4 22110 drives worth owning/buying?
[and, are there ever likely to be? (given that E1.S effectively obsoletes it; see EDSFF)]

Until E1.S drive and backplane are available at large scale, I think Gen4 22110 still has it's market especial with EPYC system that you have many free PCIe 4.0 slots sitting idle, but your 2U storage chassis doesn't have or with limited U.3 backplane or slots if you want to get full benefits of PCIe 4.0

Now few PCIe 4.0 22110 M.2 are available , for example Samsung PM9A3, Micron 7400/7450 etc

btw, This LP M.2 to PCIe Gen4 card is $26.94 only when ships from Poland, but won't ship to North America. It's actually more when ships from other location. Ordered one and let see how it works. It will probably take a month to arrive
