1. Connect the KEY-B-M SATA definition of the motherboard or the MSATA hard disk to the SATA 22PIN interface. This adapter board only connects the signal from the M.2 hard disk to the SATA 22PIN connector, so the adapter card does not need a driver. 2. The riser card is suitable for 4 different SSD hard disk lengths, suitable for 3cm, 4.2cm, 6cm, 8cm and other different M2 (NGFF) SSD hard disk lengths and full-height MSATA hard disks. 3. Using ceramic filter capacitors, high-power DC-DC voltage regulator control chip, stable performance. 4. The riser card only changes the interface form of the solid state drive, and does not change any performance of your hard drive. What are the parameters of your original hard drive, with the riser card, the performance of the output interface will not change. Parameter: 1. Product interface: SATA 22PIN male 2. PCB color: black PCB 3. Product rate: 20Gbps10Gbps 4. Support protocol: MSATA or M2 NGFF SATA, cannot be used at the same time 5. Main control chip: switch with switch 6. System support: WIN7WIN8WIN10WIN11MACLINUX Precautions: 1. Support all SATA standard M.2 SSD, do not support NVME M.2 SSD, do not support PCI-E M2 SSD 2. MSATA and M2 cannot be used at the same time, and the MSATA and M2 disks must be switched through a switch.
