1)
Note: This adapter card can support M. 2 NGFF SSDs of two protocols, but can only support the conversion of SATA M. 2 NGFF SSD to U. 2 SATA interface, or NVMe M. 2 NGFF SSD to SFF-8639 (that is, U. 2) interface! ^^ 2) The adapter card cannot support the conversion of SATA M. 2 NGFF SSD to SFF-8639 (that is, U. 2) interface or NVMe M. 2 NGFF SSD to 2.5 -inch SATA interface! ^^ 3) This product only supports the use of SFF-8643 to SFF-8639 data cable to connect to the SFF-8643 interface of U. 2 protocol. ^^ 4)
Usage method 1: NVME SSD to SFF-8639 interface, and then use the data cable to connect to the SFF-8643 interface of the motherboard. It does not support NVME to SATA or NVME to SAS! ^^ 5)
Usage 2: SATA SSD to SAS interface. The SAS interface here does not support the ordinary 2.5 -inch SATA interface and requires a matching SAS to SATA adapter card to use it (the SAS to SATA adapter card needs to be purchased separately)!
