Hyper M.2 X16 PCIe 3.0 X4 Expansion Card V2 Supports 4 NVMe M.2 (2242/2260/2280/22110) Upto 128 Gbps for Intel VROC and AMD Ryzen Threadripper NVMe Raid

Installed 2 Samsung 990 4TB NVMe SSD using this expansion card. My unit is a HP Z840 workstation. WARNING: As I bought the 990 SSDs with heat sinks, the SSDS DO NOT fit side by side on the expansion card. Also, it not possible to attach the expansion card cover either (when using heatsinked 990s). I had to use slots 1 and 3 on the expansion card. In any case, Bios detected both SSDs and I was still able to bifurcate 4x4x4x4 and subsequently create the RAID. The expansion card was inserted into the PCIe slot without its cover. To repeat, this card will only take 2 Samsung 990 SSDs with heatsinks. If you need 4, then buy the SSDs without heatsinks. This may apply to other SSDs also. Everything else is working perfectly.

THIS.. is Asus Pcie expansion for M.2 and it was a great, convenient product from a brand you trust! This Pcie expansion card fits 4 M.2 cards HOWEVER!! It is at Pcie 3.0 and not 4 so please do not waste your money on newer M.2’s and just get the best value Pcie 3.0 M.2. This product is perfect for a pcie expansion! It comes with everything you will need INCLUDING the retaining screws. It is well built in a polished metal, easy to assemble and comes with thermal pads attached to the housing so it all runs cool. This expansion card gave me exactly what I needed and looks great in my system! With the ability to keep throwing M.2’s in my system I no longer have to worry about sata cables, opening up the back of my case and managing that demon. This has been a great product for my computer, and I am sure you will find this as another great asus product just like I have!

I needed one of these to add NVME drives to an older server I run Unraid on. It took some time getting the BIOS for the motherboard configured right, but I have two 4TB Acer NVME drives installed, the OS recognizes them as allowed me to use them as a combined cache pool. Speeds are great, the fan helps keep them cool during stress periods. No complaints at this time.

I'm running this on an ASUS X370-F Gaming (AM4) with a Ryzen 3950X. I've currently got 2 Sabrent 4TB SSDs in it with full R/W speeds on Windows. If you're on an AM4 socket, you should only expect to get 2 SSDs working on it if you have a dedicated GPU. I've got a GPU taking up my first x16 slot and this card in my second. AM4 and X370 chipset doesn't provide enough lanes for a dedicated GPU and an x16 link to this card. B550 apparently has some extra lanes built into the chipset, so that *might* be an option for getting all 4 slots going once it's released. I did not need to install any drivers to get this working (though I did install some as part of troubleshooting.) Note that the four slots on the card are numbered, and on an x8 PCI-E slot, *only drives 1 and 2 will be enabled.* (Numbering starts at 1 in the top slot.) The card itself isn't recognized by Windows or the BIOS, so there's no easy way to tell whether or not the card is being detected if an SSD isn't showing up. To get it to work, in the BIOS I: - Enabled "Hyperkit Mode" in SATA device options - Set its PCI-E slot to run in "NVMe RAID" mode (despite not using RAID) - Disabled CSM completely in boot options After that my drives showed up in Windows as though the card wasn't there. Keep in mind that a BIOS update will probably reset all your settings so you'll need to re-apply them after updating. The fan on this this is noticeably loud. There is a switch on the PCI bracket for easily turning the fan on and off, which is MUCH appreciated. I've done some minor testing with my 2 drives in there and they only ever got up to ~55C with the fan off. I suspect it's unnecessary unless you've got 3+ drives installed and are hitting them all fairly regularly. The heatsink is super beefy. Documentation can be conflicting or outright missing, but if you're looking at something like this, you should expect to deal with those sorts of annoyances anyway. I can *tentatively* recommend this card if you have enough PCI-E lanes available to get the most out of it. Otherwise I'd recommend a cheaper dual-mount card, which should perform as well as this.

I decided to update my storage on my PC and got an NVME drive but didn’t have an NVME port on my motherboard so I needed a PCI card. I tried the cheap route and bought two different PCI NVME add-in cards and they both were terrible. Sometimes the would work other times not so much. I have an Asus Sabertooth motherboard and trust them so I went with this card. It’s a bit overkill for my application (NVME boot/main drive replacing SATA) but all the issues I had with the other two cards disappeared when I used this card. It’s high quality and the heat spreader really helps with dissipating any heat generated by the NVME drive/s. I don’t use the fan because it’s a bit loud but you at least have the option if you’re running 4x NVME drives in a RAID configuration and need to keep the drives from thermal throttling.

I bought this and two Crucial T500 NVME modules ( without heat spreader ) that I configured in a RAID1 mirror. The modules are pcie 4.0 capable, but my computer only has pcie3.0 which is limiting the performance. Still, I am seeing large block reads peak at 6435 and writes at 3144 MB/s. By comparison, a single mid-range SATA SSD gave 558 and 507 MB/s. This is where pcie NVME shines. For random access the drives will be the limiting factor and even SATA overhead becomes secondary. As others have said, your motherboard _must_ support pcie bifurcation to use more than one NVME drive, and you must have a full-width ( x16 ) spare slot with enough pcie lanes for the number of drives that you want to install. For one NVME drive you could get by with a pcie x4 slot. For two, an x8 slot _and_ bifurcation support is required, and for three or four an x16 slot _and_ bifurcation support. Note that the physical width of the slot is not a guarantee of having enough lanes - check the documentation on your computer or motherboard. Many, many motherboards have only a single x16 slot which is typically used for the graphics card, and an x8 slot, then either nothing more or a very small one. The Xeon boards or systems designed for workstation use are likely to be well equipped. Some new graphics cards with pcie 4.0 get by with an x8, which would allow this NVME card to use the x16. Keep in mind that any network card faster than 1G will also need at least an x4 slot. I should add that these modules were configured in a mirror using Intel's VROC, and the motherboard has a VROC dongle to enable the functionality. The computer boots from this mirror without needing any other drives. One caveat: the board is pretty heavy due to the aluminum heatsink. It is not exactly secure in a pcie socket but should be fine if the system is not being moved around. Second caveat: the system's drive LED is not connected to this module and never goes on when it is being accessed

Using in Proxmox with TrueNAS as a VM. Motherboard supported PCIe bifurcation so I'm running 3x2TB nvme mirrored (I don't need a ton of storage) but the data is important. PCI passthrough worked great and was very easy. Video buffering on NextCloud is much faster than my old external HDD. Was able to get 4.7gbps transfer rate for VM backups with Ubiquiti back end. I'm also able to sync my backups with the cloud at leisure. Great purchase.

Works Great
