M.2 NVME dual-bay USB3.2 Gen2x2 hard disk array box, aluminum alloy material, built-in cooling fan, strengthen air circulation and heat discharge, double heat dissipation is not afraid of high temperature, so that the device runs stably, quickly dissipates heat, refuses to be hot, and has good compatibility。Support Type-C3.2 Gen2x2 high-speed and stable transmission theoretical rate of 20Gbps.Support NVME PCIe NVMe Gen 3x2 protocol, support 4 RAID modes, free combination, endless exploration, security, expansion free choice, to meet the needs of a variety of usage scenarios. Indicator signal light indicates the status of the hard drive

　　1、① TPYE-C upstream port supporting USB3.2 Gen2x2 maximum transfer rate 20Gbs (backward compatible)；

　　2、② TYPE-C port, power input, 5V/1A (MAX 4A), must be connected to power to operate;

　　3、⑨ M.2 ① HDD interface, support NVME PCIe NVMe Gen 3x2 protocol, (does not support SATA M.2)；

　　4、⑩ M.2 ② HDD interface, support NVME PCIe NVMe Gen 3x2 protocol, (does not support SATA M.2)；

　　5、③ Power LED, connect to the power supply with a blue light；

　　6、⑤ M.2  ①Hard disk status red and blue indicator, connected hard disk blue light, read and write flashing, standby solid / red light error indicates that the hard disk is not connected or the hard disk is damaged in a flashing state；

　　7、④ M.2  ②Hard disk status red and blue indicator, connected hard disk blue light, read and write flashing, standby solid / red light error indicates that the hard disk is not connected or the hard disk is damaged in a flashing state；

　　8、⑦ RAID mode DIP switch，Supports 4 RAID modes：①SPAN: Recognized as a hard disk, the size is the sum of the two hard disks。②RAID 0: The capacity identified is twice the capacity of the small hard drive in the two hard drives。③RAID 1: Recognized as a minimum capacity hard drive while backing up to another hard drive。④JBOD:Recognized as two independent hard drives (factory default mode)；

　　9、⑥ Reset/fan control buttons，a)RAID reset switch (long press for 1 second to start, the indicator flashes off and the reset is completed) 。b)Fan control switch (tap Turn fan on or off with memory)；

　　10、⑪ Reset the blue indicator light, flashing when resetting work, and off when idle；

　　11、⑧ Fan interface header, after inserting the hard disk, the fan starts to rotate, and the fan does not work without connecting the hard disk；
