The KALEA-INFORMATIQUE M2 PCIe 3.0 x8 controller card allows the connection of four M.2 NVMe M Key SSDs to a computer system. This expansion card utilizes the PLX PEX 8747 chipset and operates with a PCI Express 3.0 x8 interface, providing dedicated bandwidth allocation for each SSD pair with a total capacity of 64 Gbps. The controller supports all M.2 M Key PCIe NVMe Solid State Drives and is compatible with both M Key and B+M Key SSD configurations. A significant advantage of this solution is its independence from motherboard bifurcation support, making it universally compatible with any motherboard, regardless of fork mode capability. The card accepts multiple M.2 form factors including 2230, 2242, 2260, 2280, and 22110 lengths, with all necessary mounting screws included. For flexibility, the card features a detachable extension section that can be removed when 110 mm SSDs are not used, reducing the overall length from 205 mm to 175 mm. Installation requires no additional drivers or software and offers plug-and-play functionality across multiple operating systems, including Windows 11, Windows 10, Red Hat Linux, CentOS, VMware ESXi, and Ubuntu Linux. Thermal management is addressed through forced ventilation to maintain optimal operating temperatures between 5°C and 50°C. The card measures 69 mm in width and 205 mm in length (reducible to 175 mm) with a weight of 175 grams. Both low-profile and high-profile mounting brackets are included for compatibility with various computer case configurations. The black PCB design ensures durability and reliable performance for storage expansion needs in personal computer environments.
