1) Please ensure your motherboard has a PCIe NVMe M. 2 SSD slot. SATA M. 2 NGFF SSD slots are not supported. If the interface is not compatible, the drive will not function.; 2) This product supports installing one U. 2 SFF-8639 drive in the PCIe NVMe M. 2 SSD port on your machine. This requires an SSF-8643 to SFF-8639 cable (not included).; 3) Transfer speeds vary depending on your motherboard's interface. The adapter does not change the transfer speed. The drive signal cable passes directly into your machine's PCIe NVMe M.
2 SSD slot, eliminating the need for a chip and limiting drive performance.; 4) The adapter supports four mounting positions: 2230mm, 2242mm, 2260mm, and 2280mm (the PCB can be cut; please ensure the correct distance is measured before cutting).; 5) The adapter only supports connecting U. 2 SFF-8639 drives using an SSF-8643 to SFF-8639 cable. SSD uses. (U. 2 SFF-8639 SSD is not a SAS interface, please do not confuse it)
