Maximize your PC’s storage potential with this PH44 4-Port M.2 NVMe to PCIe Adapter. This expansion card allows you to mount four high-speed M.2 NVMe SSDs onto a single PCIe (16 slot), making it ideal for gamers, video editors, and server setups requiring massive storage arrays or RAID configurations. Critical Compatibility Requirement: Please Read Before Buying: This adapter requires a motherboard that supports PCIe Bifurcation (PCIe Split function). Your motherboard BIOS must allow the PCIe (16 slot) to be split into x4/x4/x4/x4 mode. If your motherboard does not support signal splitting, it will typically recognize only the first SSD. Supported platforms generally include X299, X399, and modern server/workstation motherboards. Please verify your motherboard manual or manufacturer’s FAQ for “PCIe Bifurcation” support. Key Words: Quad M.2 Expansion: Expands a single PCIe (16 slot) to support 4 separate M.2 NVMe SSDs simultaneously.
