M.2 Key M to 5-Port SATA 3.0 Expansion Adapter Card with JMB585 Chipset, PCIe X2 NGFF NVME M-Key to SATA III 6Gbps Storage Converter

This M.2 to SATA expansion converter is built with mature JMB585 control chip, designed for motherboards equipped with spare M.2 Key M PCIe X2 slots. It turns one NGFF NVME M-key slot into five fully functional SATA 3.0 ports, solving the problem of insufficient onboard SATA ports for mini ITX small hosts, NAS and surveillance recording equipment.

Every SATA port reaches a maximum transmission speed of 6Gbps under SATA III standard, and is fully backward compatible with SATA 1.0 and SATA 2.0 hard drives. It works with all common storage brands including WD, Seagate, Samsung, Kingston, Crucial, ADATA, supporting 2.5-inch SSDs, 3.5-inch mechanical hard disks and SATA DVD optical drives. Users can assemble multi-disk RAID groups and large-capacity centralized storage systems with this adapter.

The high-performance JMB585 chip maintains balanced read-write performance when all five hard drives run at full load, avoiding common defects such as hard disk disconnection, slow speed and system unrecognition from low-grade expansion boards. The compact card structure is perfectly embedded in the M.2 slot of mini chassis, no extra PCIe slot occupation to reserve space for graphics cards and network cards.

Built-in anti-electromagnetic interference circuit reduces signal noise generated by internal power supplies and cooling fans, ensuring 24-hour stable continuous operation for storage servers and monitoring hosts. It provides complete driver support for Windows and mainstream Linux operating systems. After simple driver installation, all five SATA ports can be independently identified without bandwidth conflict.

It is an ideal space-saving storage expansion accessory for DIY mini NAS, small video editing workstations, industrial control computers and monitoring NVR devices that lack enough native SATA ports.
