Review on 💥 ASUS Hyper M.2 X16 PCIe 4.0 X4 Expansion Card: Supports 4 NVMe M.2 (2242/2260/2280/22110) up to 256Gbps, Compatible with AMD 3rd Ryzen sTRX40, AM4 Socket, and Intel VROC NVMe Raid by Jeff Long

DO I NEED this? no But I have a history of what not to do, and this was no exception. I was blown away by the price and was excited to see what four PCI GEN 4 MP600 NVME drives could do. The answer was a read speed of 20 GB/s. Run an x570 motherboard stuffed into an x16_1 slot for full fanout. You can run this on x4x4 for the record, but you can only use two NVMEs. But what's the point? That's the length and height of any modern high-end GPU, but it fits in a PCIe slot wide. It has a tiny fan which I can only imagine how much it actually helps, but the entire lid is a damn heatsink so I think they stay cool enough. I'm running this on Ubuntu with mdadm in RAID 0 and am more than happy with it. Everything just works. 4 drives are displayed. So if you want to ambush them, you'll have to do it yourself. You may be able to create a RAID in BIOS and then view them in Windows using this AMD Raid application, but not entirely sure. You can always use one storage pool, just make sure you set the appropriate columns if you choose RAID 0 to get the full benefit.
