EZDIY-FAB Quad M.2 PCIe 4.0/3.0 X16 Expansion Cad with Heatsink, Support 4 x PCIe NVME M.2 SSD, RAID-on-CPU (VROC) in Intel Platform and PCIe 4.0 RAID in AMD Platform, M/B PCIe Bifurcatin is Required

Works great, needed an extra Nvme slot but only had one on mobo. Bifurcation not supported on my board (x370) however available for future upgrade. Works full speed (pcie x4), cheaper than similar name brand products. Heat sink keeps ssd <30c, expected it to be warmer.

前から複数枚使えるM.2 スロット インターフェースボードが欲しかったので購入。問題なく使えてますが、冷却が大型のヒートシンクだけだと夏場は厳しいかも？ファンもつけたい。

Works as expected, turn on 4x4x4x4 and you're good to go.

Its a good card and its built solid. My drives worked out of the box with it. The only problem I have is the screws, there smaller than most m.2 motherboard screws, however they do include a screwdriver that works with these smaller screws. At the end of the day, its a good product.

I bought this card t go into my home server. This machine features a Gigabyte ga-7pesh2 mainboard. Once installed in the uppermost full-length PCIe slot, I had to go into the bios and enable 4x4x4x4 mode for that slot. This wasn't exactly spelled it, but it also wasn't terribly difficult to find either. After that was done, all four nvme drives showed up in the OS. I then setup a raidz set, and I was good to go. Read and write speeds are about what you would expect for this device. All in all, I am very impressed with the quality of the card and the ease in which I was able to set it up.
