NVMe M.2 to SATA 3 Expansion Card, NGFF M Key M2 to SATA3 Controller Port Multiplier, Internal M.2 NVMe Slot to Multiple SATA III Ports Converter for Desktop HDD & SSD Storage Expansion

This M.2 NVMe to SATA 3 expansion controller card is a practical internal storage extender designed for motherboards equipped with NGFF M-Key PCIe NVMe slots. It acts as a SATA port multiplier to turn one spare M.2 slot into multiple independent SATA III interfaces, solving the insufficient SATA port issue on new motherboards and supporting mass storage deployment for desktop PCs, home NAS and small workstations.

Built with dedicated SATA bridge control chip, every SATA port runs at full 6Gbps SATA 3.0 speed, supporting all mainstream 2.5/3.5 SATA hard drives and solid-state drives from WD, Seagate, Toshiba, Samsung, Crucial and more. Gold-plated SATA connectors effectively resist oxidation and signal interference to maintain consistent read/write performance under long-hour continuous workloads.

Adopting standard 2280 M.2 size, it installs directly into the motherboard M-Key NVMe slot without occupying PCIe bracket space. No extra driver installation required, plug and play on mainstream operating systems. Compact PCB layout optimizes internal chassis wiring and ventilation, paired with heat sink to lower chip temperature for reliable 24/7 operation.
