1. Ultimate 2-in-1 Hybrid: Dual 10G NIC + M.2 NVMe Slot The SKN-2BT-M2 is a professional-grade hybrid expansion card that combines Dual 10Gbps Copper Ports and an M.2 NVMe SSD slot. This innovative design allows you to upgrade your network bandwidth and storage speed simultaneously while occupying only a single PCIe slot—the perfect solution for high-density NAS and workstations. 2. Cutting-Edge Marvell® AQC113C Controller Powered by the high-performance Marvell AQC113C chipset, this card delivers enterprise-class 10GbE reliability with optimized power efficiency. It supports multi-gigabit speeds and provides stable, low-latency data transmission for demanding professional environments. 3. Dual 10Gbps RJ45 Copper Connectivity Equipped with two 10G Base-T RJ45 ports, this card supports 10G/5G/2.5G/1G/100M auto-negotiation. It allows you to achieve 10Gbps speeds using standard CAT6 or CAT6A copper cables, eliminating the need for expensive fiber infrastructure while doubling your network throughput. 4. Integrated M.2 NVMe SSD Slot Boost your system performance by adding a high-speed M.2 NVMe SSD directly to the NIC. Use the SSD as a lightning-fast boot drive or a high-speed cache for your NAS (Unraid, TrueNAS, etc.), significantly reducing data access times and improving overall system responsiveness.
