Cable interface devices and mounting assemblies are provided for data storage assemblies. A data storage assembly can include media, such as a solid-state drive, a cable interface housing, and a cable interface housing locating feature. A cable interface device is mounted within the cable interface housing. The cable interface device includes a body extending in a first direction that defines an opening at the front side with a protruding connector of a solid-state drive extended through the opening. The cable interface device further includes electrically conductive contacts at least partially disposed inside the body and exposed to the opening. The cable interface device also includes a cable interface device locating feature positioned on, or defined by, the body and complementary in shape to the cable interface housing locating feature, to collectively locate the cable interface device within the cable interface housing.
