Thank you for your inquiry. This product is for NMVe PCIe m.2 drives, such as the Trenscend drive you have mentioned, and connects via OCUlink. However, it does not allow PCIe M.2 drives to connect over SATA as they are two different protocols. The SATA connection would be specifically for the SD card.
If you have any questions or suggestions on our concept products, feel free to send us a message.
