I think it is the standard 2.5 inch SATA interface. There is word "MB" in white cable. That means motherboard. It uses to connect motherboard and SATA interface.
hi,
I have a 850 pro 256 G with windows 10. Now I have another intel 750 1.2TB. If I run the software or games from intel 750 which is not the system disk, would it decrease the efficiency comparing to installing system in intel 750?
