NGFF B+M Key M.2 2280 to 5-Port SATA 3.0 6Gbps Port Multiplier Adapter, JMB575 PM Chip SATA Expansion Converter for Desktop PC & NAS Storage Upgrade

This M. 2 NGFF B+M Key to 5-port SATA 3.0 expansion adapter adopts mature JMicron JMB575 control chip with SATA Port Multiplier function, converting a single 2280-size B+M M. 2 SATA slot into five high-speed SATA 3.0 interfaces to solve insufficient native SATA port issues on motherboards. It strictly fits M. 2 slots with SATA protocol and B+M key notch, incompatible with NVMe-only M-Key M. 2 slots. Compatible with all standard 2.5 -inch SATA SSDs and 3.5 -inch SATA mechanical hard drives, and supports cascaded PM connection to maximize storage capacity for NAS, data servers and media workstations.

Equipped with an aluminum alloy heatsink, it effectively dissipates heat during continuous high-duty read-write tasks to avoid thermal throttling. Every SATA port matches a separate LED light to display real-time disk access status for easy troubleshooting. No complicated driver installation required for mainstream Windows and Linux systems. The slim 2280 PCB design saves internal chassis space, perfectly fits ATX, MATX and mini ITX PC cases.
