SATA Data Cables look like really thin ribbons. They are ribbon-shaped cables that have even pin connectors that are identical in shape, running through the internal bottom surface of the cable. These pin connectors have a dimension of 1.5 x 0.4 cm and do not measure more than that, they also have distinct L-shaped notches for system connection. There are several SATA Data cables that are made with 90-degree angle-shaped connectors. These types of cables are not really important, but their unique function is that they are compatible with most motherboards and help during connection. Motherboards come with their own SATA Data Cables.
