Want to add serious high-speed storage to your desktop PC? This adapter card lets you install up to FOUR M.2 NVMe SSDs onto a single PCI Express x16 slot on your motherboard! Each port supports the full PCIe x4 lane speed (up to 32Gbps per drive), so you won't bottleneck your fast SSDs. It supports both PCIe 3.0 and 4.0 protocols. The card has a sturdy, thick PCB for stability and includes a high-power DC chip to ensure all drives run reliably. It requires that your motherboard supports PCIe Bifurcation or has a built-in RAID function. Each of the 4 slots has its own LED activity light. Perfect for video editors, gamers, or anyone building a powerful workstation or NAS with massive, blazing-fast storage. Includes all necessary screws and a screwdriver.
