1) This adapter card simply combines SATA to NGFF and PCIe to NVMe SSDs onto one card, allowing the two SSDs to be used independently.
2) The card not work for NVME M-key SSD to SATA host, Also can't work for NGFF B-key SD to PCIE host; It only can work for NVME M-key SSD to PCIE or NGFF B-key SSD to SATA.
3) Oculink 4x connectors are internal and external small form factor PCI-E connectors and cables optimized for the client and market; Supports M.2 modules in format 2280, 2260, 2242 and 2230 with key B or key B+M based on SATA
4) This U.2 M.2 converter enables two different usage applications.1. One M.2 PCIe SSD in 2280, 2260, 2242 and 2230 format can be connected and used as a replacement for a 2.5inch HDD. The converter can be installed into the system internally through the SFF-8611/8612 oculink interface.
5) 2. One M.2 SATA SSD in 2280, 2260, 2242 and 2230 format can be connected and used as a replacement for a 2.5inch HDD. The converter can be installed into the system internally through the SATA 22pin interface.
