The JMB585 is a bridge controller between the M.2 host and the storage devices with SATA/AHCI interface.
Its upstream port provides a M.2 which data transmission rate for PCIe Gen 3x2 specification.
Meanwhile, its downstream port can connect to SATA/AHCI storage devices, such as a solid-state drive (SSD).
The data speed of each port for the SATA port can arrive at 6Gb/s.
The M.2 Key M SATA 3.0 Expansion card used new JMB585 chip solution, high speed and stable performance, it is committed to solving user's demand for massive data space, the high-speed expansion card achieves PCI Express Gen 3x2 line bandwidth, with five SATA ports extending from the PC host to the M.2 Key M slot, each port with a transmission speed up to 6Gbps. it can be widely applied to personal computers and other big data storage devices.
