ASUS Hyper M.2 x16 Gen5 PCIe 5.0/4.0 Expansion Card - Supports 4 NVMe M.2 SSDs (2242/2260/2280/22110) up to 512Gbps, Compatible with AMD & Intel Platforms with RAID Support - Perfect for Gaming PCs, Workstations & High-Performance Computing

The product does exactly what it says it does -- you can install up to four NVME sticks. It's a full-sized card, with a fan and a heat sink to keep the NVMEs cool. If you need to build a high-performance file server, this would be one way to do it.Be advised, the maximum number of NVME devices depends on how much available PCIe bandwidth your motherboard has. It will not support as many NVME devices if you lack the PCIe bandwidth. You may encounter problems if you add this to a computer that already has a high-performance video card or other accessories that use most of your PCIe bandwidth.
