ASUS 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

The ASUS Hyper M.2 X16 V2 is a fantastic way to add four high-speed NVMe drives to a server build. It’s well-built and features a massive heatsink and fan to prevent thermal throttling. However, this card does not have an onboard RAID chip; it relies on PCIe Bifurcation. If your motherboard cannot split an x16 slot into x4/x4/x4/x4, you will only see one drive. When supported, the performance is incredible, but do your homework on your specific motherboard compatibility before buying.

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.

Great brand new condition as advertised. works perfect!

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 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.

You need to enable "bifurcation" or x4x4x4x4 setting on the usb slot you're going to plug this into, and that setting is in the bios. Once you've done that, you can create a shared file system across the 4 nvme drives you've plugged in, or a software raid setup of some sort (I chose the former). The problems happen when you update the bios. This might happen months later, where you decide your machine's bios needs an update, and all your changes to the bios get wiped. Suddenly you try to boot your system and it can't find the drives. With Linux, this can cause the system to not boot, if you're auto-mounting the combined drive, because only one of the 4 nvme drives attached to the card, can be seen. Anyways, not totally for the inexperienced, definitely understand the limitations. Your system might not even support bifurcation, and you'll see a lot of complaints along those lines like ("can't see all 4 drives"). etc. Overall review of 5/5 because it does what it says, and does it without failure (maybe 3 months so far).

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

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!

冷却と見た目の目的で購入。 M/B側で、PCI-E x16スロットの設定を、x16 → x4,x4,x4,x4に変更できないと、 使用できませんので要注意です。 ちなみにx8 → x4,x4とした場合は、No1とNo2のみ認識し、No3とNo4は認識しません。 BIOSで設定できない場合は、No1のみ認識します。 あとPCI-Eのレーン数も影響するので、注意を。

Can't go wrong with this if you want to add more nvme storage to your PC. Awesome build quality and pretty much requires zero configuration besides enabling NVME RAID MODE in the BIOS (depending on your motherboard).

Good product

There seems to be a lot of misinformation about this card and I hope that my experience will help to clear up some of the thud! Note that I am not using Intel or other supported drives so I will not cover VROC here and my aim with this card was to simply add some additional NVME drives to my system. Firstly, for this card to work with more than one drive you will need a motherboard & a version of BIOS that supports PCI Bifurcation. I'm using this card in a Maximus X Hero (Wifi-AC) Z370 motherboard with BIOS 2203 (2019/10/17). The Maximus X Hero supports PCI Bifurcation on PCIEX16/8_1 or PCIEX8_2. As I'm using a discrete GPU in the first slot I have the Hyper M.2 card plugged into PCIEX8_2. PCI Bifurcation "splits" the x8 slot into 2 x4, thus supporting 2 x NVME drives. If I was not using a discrete GPU then I would be able to support 4 x NVME drives in my system. If you need to support 4 drives and a discrete CPU then you'll need X299 or an NVME carrier card with a PLX chip such as the one's from HighPoint $$$! My GPU is now running at x8 not x16 due to the limited PCI Express lanes on Z370. I also have an Asus PCE-AC88 Wifi card connected to the system along with NVME drives in each of the two motherboard M.2 slots. As other reviews have covered, the build quality of the card is simply excellent, basically it's a large, very nicely machined aluminium heatsink. I have the internal fan disabled as it can be a little noisy but I also don't find that it is required. I live in Asia with an ambient temperature of over 30 Degrees yet my Intel 660p and Adata SX8200 Pro peak at 46 degrees. Overall this is a fantastic card for adding additional drives to systems that support PCI Bifurcation!
