PCIe 5.0 x16 to Dual M.2 NVMe Expansion Card (READ BEFORE BUY: Motherboard MUST Support PCIe Bifurcation x8x4x4), M-Key Storage Adapter

PCIE 5.0 HIGH BANDWIDTH: Supports PCIe 5.0 and is backward compatible with PCIe 4.0 and PCIe 3.0, delivering high bandwidth for M.2 M-Key SSD arrays and professional workloads to support fast storage expansion.
PCIE 5.0 SPLIT DESIGN: With a PCIe 5.0 bifurcation design, the adapter splits a PCIe x16 slot into x8 / x4 / x4 lanes, allowing two NVMe-compatible SSDs to run at full speed when the motherboard supports PCIe signal splitting.
VERSATILE COMPATIBILITY: Accommodates up to two M.2 M-Key or Serial ATA SSDs on both sides of the card, supporting 2230, 2242, 2260, 2280, and 22110 drive sizes for flexible system configurations.
ENTERPRISE-LEVEL SUPPORT: Compatible with U.2 and NVMe adapters, and supports SFF-8639 U.2 adapter cards, making it ideal for enterprise SSD data centers and high-performance storage systems.
ROBUST PCB DESIGN: Features a stable multi-layer PCB structure offering strong anti-interference capability, precise impedance control, and stable PCIe signal transmi
