Features: M.2 NGFF interface SSD has many kinds of pin definitions, according to the Key bit can be divided into A.B.C.... until M key. According to the size, it can be divided into 2230, 2242, 2260, 2280, 22110 specifications. According to the data transmission protocol, it can be divided into B+M key SATA data transmission protocol, B+M key PCIe x2 AHCI data transmission protocol, B+M key PCIe x2 NVMe data transmission protocol, M key PCIe x4 AHCI data transmission protocol, M key PCIe x4 NVMe data transmission protocol. Again, this product only supports M.2 NGFF interface in the PCIE x4 AHCI NVMe transfer protocol of the SSD (SSD only has a gap) and PCIE x2 AHCI NVMe transport protocol SSD (this kind of SSD has two interfaces, but the transfer protocol is PCIE X2, such as Picot's M6E series, please be sure to distinguish, there are two gaps also have SATA transfer protocol. This riser card can only support SATA M.2 NGFF SSD conversion to SATA interface or NVMe M.2 NGFF SSD to SFF-8654 interface! These are two separate separate passages! Can not support SATA M.2 NGFF SSD conversion to SFF-8654 interface use or NVMe M.2 NGFF SSD to 2.5 inch SATA interface use! Specifications: Product Name:SATA M.2 SSD to SATA,NVMe M.2 NGFF SSD to SFF-8654 Adapter Chip:None Color: Black Product size:120x49mm Input Interface :SATA or SFF-8654 Output Interface:SATA M.2 or NVMe M.2 Power Supply: No additional power supply required Compatiblle SSD size: 2230, 2242, 2260, 2280 Support system: Windows XP/2003/Vista/Win7/Win8/Win10 (32/64bit) ,MAC,Linuxoperating systems Transmission sppeds:This riser card only provides interface conversion and does not affect the transfer speed, which depends on the speed of your hard disk Note: 1 This product does not support NVMe M.2 hard disk to SATA interface! 2 This riser card is generally used to connect to the following motherboard interface with SFF-8654 to SS-8654 cable! Package includes: 1 x SATA M.2 SSD to SATA,NVMe M.2 NGFF SSD to SFF-8654 Adapter
